A shop sells shoes in sizes 5, 5, 6, 6, 6 and 7 during one morning. What is the modal shoe size? Enter the shoe size.

الشرح

Size 6 is sold three times while size 5 is sold twice and size 7 once, so size 6 reaches the highest frequency and is the modal size. Answering 3 gives the number of pairs sold in that size, which is the frequency attached to the mode rather than the size the question asks for.
