Question

A researcher observes the level of aggression of six 5-year-old boys over the course of a school day. The number of incidents for the group of boys was 2, 4, 6, 12, 8, 10. What is the mean number of aggressive acts for this group of children

Answer 1

7

Explanation:

Mean number = Sum of all the numbers/ Total number of old boys

Given the data

2, 4, 6, 12, 8, 10

Sum = 2+4+6+12+8+10

Sum = 42

Total number of old boys = 6

Substitute into the formula

Mean number of aggressive acts = 42/6

Mean number of aggressive acts = 7

Hence the mean number of aggressive acts for this group of children is 7
