Find the mean of the data in the pictograph below.

Irina-Kira [14]

Final Answer:

mean = 4 sundaes

Solution:

each bowl of sundaes contains 3 sundaes.

two scoops = 4 sundae bowls
I scream = 6 sundae bowls
dream scream = 2 sundae bowls

Sundays = 4 sundae bowls

(plus 3, the number three represents how many sundae's there are in a bowl)

(divide it by 12, since there are 12 numbers in the data set)

Mean = (4 + 4 + 4 + 6 + 6 + 6 + 2 + 2 + 2 + 4 + 4 + 4) ÷ 12

= 48 ÷ 12 = 4
