To explain the concepts of hypothesis testing (null and alternative hypothesis statements), I use an example of James Bond. You can also download the Boxplot guide below for future reference. Add asterisks if data outside outlier range.Calculate Interquartile Range (IQR) by taking Q3 – Q1 = 150 – 141.5 = 8.5.Determine 3rd quartile (75th percentile) = 150.Determine 1st quartile (25th percentile) = 141.5.Determine Median (50th percentile) = 146.Let’s breakdown the chart to help clarify it. Ultimately, the very next question is always “how are the box and lines calculated?” The short whiskers indicate clumps of data near the box endpoints. Blend 2 has the lowest median and greatest variability, with an interquartile range of 11.72.Blends 1 and 3 appear to have roughly similar medians and variability.The boxplot for the paint data shows that paint blend 4 has both the highest median and least variability, with an interquartile range of only 3.10.You should be able to draw some simple conclusions from the chart ![]()
