Find the mean of the numbers: 12, 15, 18, 21, 24
The heights of 5 students are 140 cm, 142 cm, 145 cm, 148 cm, and 150 cm. What is their mean height?

If the mean of 6 numbers is 15, what is the sum of all 6 numbers?
Sample Questions
Find the median of the even numbers: 2, 8, 4, 6, 10, 12
Show answer
7
Arrange in order: 2, 4, 6, 8, 10, 12. Since n=6 (even), median = (3rd term + 4th term) ÷ 2 = (6 + 8) ÷ 2 = 14 ÷ 2 = 7
Which of the following are correct about the mean? (Select all that apply)
Show answer
Mean is also called arithmetic mean, Mean = Sum ÷ Number of observations, Mean can be a decimal number
Mean is the arithmetic mean, calculated as sum divided by count, and can be decimal. It's not always equal to median, and median (not mean) is the middle value.
The mean of 4, 6, 8, and x is 7. Find the value of x.
Show answer
10
Mean = (4 + 6 + 8 + x) ÷ 4 = 7. So (18 + x) ÷ 4 = 7. Therefore 18 + x = 28, so x = 28 - 18 = 10
If each observation in a dataset is increased by 5, how does the mean change?
Show answer
Mean increases by 5
This is a property of mean: if each observation is increased by a constant 'a', then the mean also increases by the same constant 'a'.
