Question

What is the mean of 8,5,9,5,5,7,3

Answer 1

Our answer is: 6

`\Large\textsf{\textbf{Explanation}}`

We are asked to find the mean of the following dataset:

8, 5, 9, 5, 5, 7, 3

To find the mean of a dataset, add all the data values, and then divide by how many there are, like this.

S T E P 1 -

8 + 5 + 9 + 5 + 5 + 7 + 3 = 42

S T E P 2 -

(there are 7 numbers in the set)

42/7 = 6

`\therefore` our answer is 6.

Answer 2

Answer: 6

Step-by-step explanation

Add up the values to get 8+5+9+5+5+7+3 = 42

Then divide over the sample size (aka number of values). There are 7 values in this set.

42/7 = 6 is the mean
