Question

What is the mean of the data set : {2, 3, 2, 4, 5, 5, 8, 1, 3, 1}?

Answer 1

3.4

Explanation:

Mean is the average. Add all the numbers together and divide by 10 since there are a total of 10 numbers in the set.

2 + 3 + 2 + 4 + 5 + 5 + 8 + 1 + 3 + 1 = 34

34/10 = 3.4

Answer 2

Answer: 3.4

Explanation:

The mean (also known as the average) can be found by adding the numbers together and dividing by the number of values in the data set.

`\displaystyle (2+3+ 2+4+5+5+ 8+ 1+ 3+1)/(10)`

`\displaystyle (34)/(10)`

3.4
