4.2, 1.4, 2.1, 0.4, 1.3, 2.0, 1.8, 3.2*

Answer 1

1.93

Explanation:

1.To find the mean you need to add all the numbers

2. Next divide by how many numbers they are

Example:

1,2,3,4

1. Add the numbers together

(1+2+3+4=10)

2. Divide by how many numbers they are

(There are only 4 numbers)

So..... 10 ÷4 =2.5

So 2.5 is the mean
