WebJan 5, 2024 · Make a box and whisker plot. Make a box and whisker plot for each column of x or each vector in sequence x. The box extends from the lower to upper quartile values of the data, with a line at the median. The whiskers extend from the box to show the range of the data. Flier points are those past the end of the whiskers. WebMar 3, 2024 · To install Python NumPy, go to your command prompt and type “pip install numpy”.

WebAug 1, 2024 · So a rule of thumb to determine if a data point is extreme is to compare it against the interquartile range. It makes sense to use the interquartile range (IQR) to spot outliers. The IQR is the range of values between the first and third quartiles, i.e., 25th and 75th percentiles, so it will include the majority of the data points in the dataset.
