A composite bar chart showing ice cream sales. The horizonal axis is labelled with days of the week from Monday to Sunday. The vertical axis shows the frequency of sales. Each composite bar is made up of orange and blue bars which are joined together to make longer bars. A key shows that blue represents beach front sales and orange represents sales in the town centre. The frequencies for each bar are as follows: Monday: total = 41, blue bar = 12 Tuesday: total = 40, blue = 15 Wednesday: total = 30, blue = 11 Thursday: total = 24, blue = 9 Friday: total = 40, blue = 18 Saturday: total = 78, blue = 49 Sunday: total = 72, blue = 43 The orange bars can be calculated from these values.
