Document Summary

For numerical data, we can use frequency histogram and relative frequency histogram to get understanding of the shape of the distribution. The main difference from the box whisker plot and previous graphical display is that the box whisker plot shows some the values of descriptive statistics. To draw a box whisker plot, we need: find the five number summary of the data set, construct an appropriate horizontal scale, to form a box with q1 and q3 determining the location of the sides, the median is indicated by a line across the box; and the mean may be indicated with a + sign, to draw the whiskers, we follow, they cannot past the inner fences, they must end at a data point. Casio calculator: (if necessary, round your answers to one decimal place. Question 6 the smallest value on the left whisker (i. e. the left whisker ends at what value) is: 2. 5, 1. 9 c) d, none of the above.
