Find the Mean 1.1 , 4.3 , 5.6 , 7.3 , 7.3 , 4.1 , 2.1 , 4.1

$1.1$ , $4.3$ , $5.6$ , $7.3$ , $7.3$ , $4.1$ , $2.1$ , $4.1$

Step 1

The mean of a set of numbers is the sum divided by the number of terms.

$\frac{1.1 + 4.3 + 5.6 + 7.3 + 7.3 + 4.1 + 2.1 + 4.1}{8}$

Step 2

Simplify the numerator.

Add $1.1$ and $4.3$ .

$\frac{5.4 + 5.6 + 7.3 + 7.3 + 4.1 + 2.1 + 4.1}{8}$

Add $5.4$ and $5.6$ .

$\frac{11 + 7.3 + 7.3 + 4.1 + 2.1 + 4.1}{8}$

Add $11$ and $7.3$ .

$\frac{18.3 + 7.3 + 4.1 + 2.1 + 4.1}{8}$

Add $18.3$ and $7.3$ .

$\frac{25.6 + 4.1 + 2.1 + 4.1}{8}$

Add $25.6$ and $4.1$ .

$\frac{29.7 + 2.1 + 4.1}{8}$

Add $29.7$ and $2.1$ .

$\frac{31.8 + 4.1}{8}$

Add $31.8$ and $4.1$ .

$\frac{35.9}{8}$

Step 3

Divide $35.9$ by $8$ .

$4.4875$

Step 4

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.
