1Look at the plot of students' heights with points A, B, C, D and E. What kind of graph is it?
2What do the points A, B, C, D and E on the height plot show?
3What is the part from point A to B, and from point D to E, called?
4What is the part from point B to D called?
5What are the values of the points A, B, C, D and E in the height plot?
6The ages of eleven students, in years, are 13, 17, 16, 14, 11, 13, 10, 16, 11, 18 and 12. Find the lowest value, first quartile, median, third quartile and highest value, and show the data in a whisker box plot.
7The weights of seven children, in kilograms, are 28, 35, 31, 40, 26, 33 and 38. Find the five values needed and describe the whisker box plot.
8Why must the data be arranged in ascending order before the quartiles are found?
9Two classes have the same mean mark. Why might their whisker box plots still look very different?
10In the height plot, which quarter of the students is more spread out: the shortest quarter or the tallest quarter? Give a reason.
