7/30/2023 0 Comments Define interquartile range in mathIf a value has a high enough or low enough z score, it can be considered an outlier. You can convert extreme data points into z scores that tell you how many standard deviations away they are from the mean. Statistical outlier detection involves applying statistical tests or procedures to identify extreme values. Many computer programs highlight an outlier on a chart with an asterisk, and these will lie outside the bounds of the graph. This type of chart highlights minimum and maximum values (the range), the median, and the interquartile range for your data. You can use software to visualize your data with a box plot, or a box-and-whisker plot, so you can see the data distribution at a glance. You sort the values from low to high and scan for extreme values. Example: Sorting methodYour dataset for a pilot experiment consists of 8 values. ![]() This is a simple way to check whether you need to investigate certain data points before using more sophisticated methods. You can sort quantitative variables from low to high and scan for extremely low or extremely high values. You can choose from several methods to detect outliers depending on your time and resources. ![]() While you can use calculations and statistical methods to detect outliers, classifying them as true or false is usually a subjective process. In practice, it can be difficult to tell different types of outliers apart. Your standard deviation also increases when you include the outlier, so your statistical power is lower as well. The average is much lower when you include the outlier compared to when you exclude it. Example: Distortion of results due to outliersYou calculate the average running time for all participants using your data. This type of outlier is problematic because it’s inaccurate and can distort your research results. ![]() This data point is a big outlier in your dataset because it’s much lower than all of the other times. You record this timing as their running time. Outliers that don’t represent true values can come from many possible sources:Įxample: Other outliersYou repeat your running time measurements for a new sample.įor one of the participants, you accidentally start the timer midway through their sprint. It’s important to select appropriate statistical tests or measures when you have a skewed distribution or many outliers. True outliers are also present in variables with skewed distributions where many data points are spread far from the mean in one direction. But these extreme values also represent natural variations because a variable like running time is influenced by many other factors. Most values are centered around the middle, as expected. Your data are normally distributed with a couple of outliers on either end. Example: True outlierYou measure 100-meter running times for a representative sample of 560 college students. True outliers should always be retained in your dataset because these just represent natural variations in your sample. What you should do with an outlier depends on its most likely cause. ![]() Other outliers may result from incorrect data entry, equipment malfunctions, or other measurement errors.Īn outlier isn’t always a form of dirty or incorrect data, so you have to be careful with them in data cleansing. Some outliers represent true values from natural variation in the population. Outliers are values at the extreme ends of a dataset. Frequently asked questions about outliers.Example: Using the interquartile range to find outliers.Many people argue that the interquartile range represents a more effective measurement than the median or mean because it provides insights into how the data is dispersed as opposed to giving a single number. For example, how students will typically perform on an exam or the salary levels of a set of employees working in a given industry. It is frequently calculated as a means of identifying what the range of an average performance should be. The interquartile range (IQR) is the range from the 25 th percentile to the 75 th percentile, or middle 50 percent, of a set of numbers. How to use the Interquartile Range Calculator:ġ) Enter each of the numbers in your set separated by a comma (e.g., 1,9,11,59,77), space (e.g., 1 9 11 59 77) or line break.Ģ) Click on the "Calculate" button to calculate the interquartile range. You can use this interquartile range calculator to determine the interquartile range of a set of numbers, including the first quartile, third quartile, and median.

The channel's chyron even read: "NICKI MINAJ: COUSIN'S TESTICLES BECAME SWOLLEN" - though the original tweet had claimed her cousin's friend's testicles had become swollen.ĭuring her Instagram Live appearance, Minaj did acknowledge the humor of an entire news cycle dedicated to the size of her cousin's friend's genitalia. Her vaccine skepticism did earn praise from an unlikely source: right-wing media. In an earlier Tweet that kicked off the whole news cycle, Minaj said that she had skipped the 2021 Met Gala because of the event's vaccination requirement. She also told her more than 22 million followers to "pray on it & make sure you're comfortable with ur decision, not bullied." His friend was weeks away from getting married, now the girl called off the wedding." "My cousin in Trinidad won't get the vaccine cuz his friend got it & became impotent. The "Super Bass" singer faced hefty backlash for her original Monday tweet, which read: "As we have with others, we offered a call with Nicki Minaj and one of our doctors to answer questions she has about the safety and effectiveness of the vaccine," a White House official told Bloomberg. Minaj also claimed to have received an invitation to the White House Wednesday - though the Biden Administration denied that statement as well, saying it only offered her a phone call with a doctor to explain the benefits of COVID-19 vaccines. Twitter disputed Minaj's characterization late Wednesday night, with a spokesperson telling Vulture: "Twitter did not take any enforcement action on the account referenced." ![]() "Unfortunately, we wasted so much time yesterday running down this false claim," he said. ![]() ![]() Want a daily wrap-up of all the news and commentary Salon has to offer?

"As we stand now, there is absolutely no reported side effect or adverse event of testicular swelling in Trinidad," the country's health minister, Terrence Deyalsingh, said during a press conference. "And none that we know of anywhere in the world," he added. The country's health ministry said it could not find any evidence that any patient had reported the symptoms that Minaj described - in Trinidad or elsewhere. The Trinidadian-born artist repeatedly claimed that she did not "give any facts" about the vaccine and that she was simply "asking questions" - though her claims were debunked by the government of Trinidad and Tobago earlier on Wednesday. "Twitter, a place where people say the most horrific things every day." "I have been suspended from Twitter," she said, over a shot of what appeared to be an apartment ceiling. Rapper Nicki Minaj went on a wild Instagram Live rant Wednesday night after claiming she was suspended from Twitter for a post in which she said her cousin's friend in Trinidad and Tobago became impotent and suffered swollen testicles after receiving a COVID-19 vaccine. ![]() ![]() I am usually the first to acknowledge that there is rarely any time when gossip-style news should be discussed, let alone deemed “important,” especially in relation to art, whose definitive artistic motivations shouldn’t allow for any culturally-reflexive speculation to add further meaning to. She probably enjoys the fact that she got under Cameron’s skin so much, especially if Cameron really did have a close relationship with Spike Jonze.If the above title sounds a bit too “National Enquirer”-y for you, I apologize. I have my doubts whether Sofia even cares if Cameron is mad at her. If Camy and Sofia are burying the hatchet, then good for them. But Faris has had to answer questions about it in several interviews, and Faris always denies that her performance is in any way mocking Cameron. Is it true that Cameron has never spoken about it? Probably – I can’t find anything. “And she has never publicly addressed the movie scenes in question. “Cameron still refuses to talk to Anna,” the insider says. Probably helping the situation, Coppola has since split with Jonze and is happily married to rock star Thomas Mars of Phoenix.īut despite her truce with Coppola, for Diaz, the scene still seems to sting, according to the source. Says the source, Dunst, who starred in Coppola’s Virgin Suicides and Marie Antoinette, “felt that after all these years, it was time they buried the hatchet.” ![]() Oddly enough, the source says that it was the pair’s mutual friend, Kirsten Dunst, who got them talking again. “They had drinks this summer and cleared the air, possibly even paving the way for a future collaboration.” “There has been a thaw in the relationship between Sofia and Cameron in recent months,” the insider says. I could probably name eight people that she was based on, just that bubbly, extroverted blonde that you see on talk shows…It wasn’t a slight at anyone in particular.”īut it still made things tense between her and Diaz, says the source - until now. In the movie, Faris plays a dumb blonde actress who flirts with the husband of the intellectual lead character, portrayed by Scarlett Johansson and based on Coppola herself.Ĭoppola has insisted that Diaz wasn’t her muse, telling the Daily Beast ”The actress was based on a bunch of people, just that type. “It only got worse when the film came out and it became pretty well-known that part of the movie was based on their real-life feud.” “Sofia and Cameron have had an incredibly difficult relationship since 1999, the year Sofia married Spike,” a source close to Diaz says. It’s only now, has learned, that Diaz has forgiven her former friend Coppola for the supposed slight! At the time, Anna Faris‘ ditzy blonde character in director Sofia Coppola‘s film was widely interpreted as being based on Diaz, as a kind of retaliation for her alleged flirtation with Coppola’s husband, Spike Jonze. ![]() Lost in Translation was released more than ten years ago, but the film is still having an effect on Hollywood - specifically, on Cameron Diaz. Well now Radar claims that Sofia and Cameron are close to burying the hatchet: There was said to be something like a Cold War between them, no “shots fired” per se, but there was resentment on Cameron’s part. Faris doesn’t play her as vindictive or villainous, but the character seems self-absorbed, too cutesy and annoying.Īfter that, there were stories over the years that Cameron and Sofia didn’t get along. I should say that the blonde actress character comes across as an a-hole. Jonze and Diaz had worked together on Being John Malkovich, and many people simply thought, “Wow, Sofia hates Camy Diaz.” It was almost like Sofia Coppola – who wrote and directed Lost In Translation – told Anna Faris, “Do an impression of Cameron”. Faris did such an uncanny impression of Cameron Diaz, it’s not even funny. Faris’ character is ditzy, a little crazy and all over the husband character. In the movie, the husband runs into an actress he worked with, played by Anna Faris. For those of you who haven’t seen the film, these are the basics you need to know: Scarlett Johansson’s character (based on Sofia Coppola) has traveled to Japan with her husband, played by Giovanni Ribisi (based on Sofia’s then-husband Spike Jonze). If you’ve seen Lost In Translation, you’ll not only understand this story, you’ll enjoy it too. 7/30/2023 0 Comments Joseph ducreux marie antoinette![]() ![]() In particular, the queen ordered a lot of portraits by Élisabeth Louise Vigée-LeBrun, as well as some by other artists.

I love Howl and Sophie, and I love how Sophie’s perspective on the world changes when the spell makes her old, and I love her bravery and resourcefulness and determination. Like all DWJ books the plot gets a bit twisty and you need to keep your head straight to figure everything out (she’s the queen of making tiny references to stuff early in a story which turn out to be massively significant at the end, and if you’re anything like me you’ll be flicking back and forth here to check you’ve got the right end of the stick!), but I just love this book. Thus begins an adventure which is so charming, so clever, and so downright funny that I can’t recommend it highly enough. Plus, she figures Howl is the only person she knows of whose magic is equal to the Witch of the Waste’s, and maybe he can set her right once again. ![]() ![]() ![]() What’s the worst this whipper-snapper can do to me?’ and decides to go up and let herself in. Because the spell has changed Sophie into a 90-year-old woman, she looks up at this place, which had frightened her so much as a younger woman, and thinks ‘Heck. In desperation, she sets out to try to seek her fortune and find a solution to her problem and – of course – she encounters Howl’s castle. While he is in town, Sophie meets with the Witch of the Waste, who has taken umbrage at Sophie’s attempts to work magic, and she is placed under a spell which changes her appearance utterly – and part of the spell is that she can’t tell anyone she’s under it. His castle is as frightening as he, even though nobody seems to know what he looks like or who he is. Howl is reputed to eat the hearts of young girls, and his power is said to be vast. They all do well Sophie begins, gently, to weave spells into the hats she makes, and Martha and Lettie discover how a little magic can go a long way.Īnd then the wizard Howl, in his tall black castle which never stays still, comes to town. When their father dies, the girls are apprenticed – Sophie stays at home and learns to be a milliner, Lettie is sent to the local pastry shop, and Martha to a witch to learn her trade. The girls and their parents live in the land of Ingary, you see, where magic is real and fairytales are a way of life, and these roles for the sisters seem entirely natural. Sophie, as the eldest, knows she is destined for a hard-scrabble life where she must set forth and try to make her fortune. Howl’s Moving Castle is the story of Sophie Hatter and her sisters Lettie (the pretty one, in the middle, destined never to amount to much) and Martha (the youngest, destined for an easy life and a good marriage). It’s funny how an author I love so much divides me so completely, but there you have it. These books are, for me, examples of masterful literature which just happens to be written for young readers. These are the types of books I aspire to create. Then there are books like Enchanted Glass, and Fire and Hemlock, and A Tale of Time City, and The Power of Three, and Howl’s Moving Castle. I read The Merlin Conspiracy recently and enjoyed the story, but holy heck it dragged on far too long and didn’t need all the pages upon pages of exposition and description. Eight Days of Luke is a book I thought I’d love, given that its central character is – whoops! I nearly gave it away! – but I didn’t think much of it. The Chrestomanci series, about the wizards of Caprona, for instance, delights most people but leaves me utterly unmoved.

Short, narrow concentrator nozzles provide curly and frizzy hair the opportunity for a sleek blowout, since their powerful flows are great for eliminating frizz. ![]() They come in different sizes for varying purposes: Broad, extended concentrator nozzles are meant for larger surfaces and are "useful for thick and long hair as they help it dry faster," Wizemann says. Concentrators narrow the hair dryer's airflow to blow air directly on the hair for smooth, sleek styles. ![]() Diffusers are great for curly hair because they circulate air to the ends of hair while diffusing the airstream from the hair dryer to prevent frizz, which can help to define curls and even add volume.These are the two you'll most commonly find included with your hair dryer or sold separately: ✔️ Attachments, which really make a difference on various hair textures since they affect the airflow of a hair dryer. ✔️ A djustable heat and speed settings, which allow you to customize the level of heat and power the hair dryer emits according to your hair type and preferences. When purchasing a top quality hair dryer, there are several factors to consider, GH Beauty Lab scientists say: Finally, each hair dryer's noise emission level is determined via the third-party certifier Quiet Mark, which issues a star rating based on recorded sound level tests. In addition, we rate ease of use, including comfort of hold, ease of putting on and removing attachments, location and ease of controls and buttons, and any potential irritation or damage to scalp, skin or hair. In the Lab, scientists evaluate hair dryers across price points and power ratings (ranging from 1,500 to 2,000 watts) by measuring drying speed on standardized human hair samples, airflow force, weight, air and surface temperature and cord length. These included dozens of airflow and temperature experiments and weight and cord length measurements. In the GH Beauty Lab's most recent test, our scientists evaluated 41 hair dryers over eight weeks (for a total of 320 hands-on testing hours), recording 2,244 data points to determine the winning models. The Good Housekeeping Institute Beauty Lab has been testing hair tools, including hair dryers - plus hair dryer brushes and travel hair dryers - for over a decade. Thousands of data points were then tallied to compile this list of the best hair dryers you can buy. In the most recent test of hair dryers, GH Beauty Lab analysts evaluated 41 products in the Lab and at home for ease of use, performance, drying time and more. GH Beauty Lab experts rigorously test hair dryers in our Lab on human hair samples and consumer testers to assess how well they work and whether they cause hair damage. ![]() We've got the full blow-by-blow on the best hair dryers you can buy from Good Housekeeping Institute Beauty Lab scientists and professional hairstylists. But it's tricky to know where to start, with so many models on the market and seemingly endless factors to consider, from your hair type and concerns to each blow dryer's technology and your desired features. For the best results, "you need the maximum amount of power with the best type of airflow to protect the hair, combined with the lightest weight possible," explains Michelle Cleveland, celebrity hairstylist and owner of Hair Addict Salon in Toms River, New Jersey. One of the keys to getting stunning, professional-level blowouts at home is a top-quality hair dryer. Our top picks, based on testing notes from the Good Housekeeping Institute, remain the same. We updated this article in January 2023 to ensure the information reflected current prices, features and more. |
