How to interpret a boxplot graph? In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25...
Further, we can use the standard_error to calculate a confidence interval for mean_skill. This assumes that the distribution of the results is Gaussian, which you can check by looking at a Histogram, Q-Q plot, or using statistical tests on the collected scores. ...
