Create a box plot for the data from each variable and decide, based on that box plot, whether the distribution of values is normal, skewed to the left, or skewed to the right, and estimate the value of the mean in relation to the median. d. If you had been given 25 data points instead of 10, would you expect the mean to be greater, less than, or about the same as the mean of this sample? A boxplot illustrates the range and the interquartile range (IQR), both of which are measures of the variation in a data set. Mean, median, mode and range; Level 6-7. The elements required to construct a box and whisker plot outliers are given below. We have seen that even though the box plot does not explicitely include the mean, it is possible to get an approximate idea about it by comparing it against the median and the skewness of the box plot: if the distribution is skewed to the left, the mean … The method to summarize a set of data that is measured using an interval scale is called a box and whisker plot. Solution: Step 1: Arrange the data in ascending order. A small wooden box arrives on the doorstep of a married couple, who know that opening it will grant them a million dollars and kill someone they don't know.
