• Misreads which bar/category a legend refers to on a bar chart

  Misread which bar belonged to which shop in the legend, naming the wrong shop as having sold more.

• Gives a correctly summed total as the final answer instead of dividing by the number of values to find the mean

  Correctly added the North branch's four daily values (26) but didn't divide by the number of days (4) to find the mean.

• Misreads which bar/series in a chart corresponds to which category, leading to an incorrect comparison or total

  Misread which bar belonged to which team in Match 2, naming the wrong team as having scored more - or, in part (c), added the totals incorrectly and picked the wrong team (Reds scored 2+0+4+1=7 in total, Blues scored 1+3+4+2=10, so Blues scored more overall even though the two teams were tied in Match 3).
