    PLEASE HELP Box and Whisker Plots

    Hi, I have a question which gives me the amount of sugar content % in a range of cereals from 3 brands: A, B and C. I've determined the mean % of total sugars, sample standard deviation, five number summary and produced a box and whisker plot for each brand. I am asked to compare the results of the three companies and comment on the measures of centre and measures of spread. It suggested I get a screen shot from my TI84 calc of all three boxplots on one screen to compare. PLEASE PLEASE PLEASE help me understand what I'm being asked to discuss and explain to me how I discuss the "measures of centre and spread". Thanks so much!
