Question

1.

Chloe made a list of her homework marks.
4 5 5 5 4 3 2 1 4 5
(a) Write down the mode of her homework marks.
(B) Work out her mean homework mark.

Answer 1

mode = 5, mean = 3.8

Explanation:

mode is the number that occurs most. there are four 5s, three 4s, one 3, one 2, one 1.

so the mode is 5 since there are more of them than any other number.

mean = (sum of the numbers) / how many there are.

mean = (4 + 5 + 5 + 5 + 4 + 3 + 2 + 1 + 4 + 5) / 10

= 38/10

= 3.8
