Studdy Solution

STEP 1

1. The data set consists of the numbers: 2,3,4,5,8,8,122, 3, 4, 5, 8, 8, 12.
2. The mean (average) is calculated by dividing the sum of all data points by the number of data points.

STEP 2

1. Sum all the data points.
2. Count the number of data points.
3. Divide the sum by the number of data points to find the mean.

STEP 3

List the data points and calculate their sum:
2+3+4+5+8+8+12 2 + 3 + 4 + 5 + 8 + 8 + 12
Calculate the sum:
2+3+4+5+8+8+12=42 2 + 3 + 4 + 5 + 8 + 8 + 12 = 42

STEP 4

Count the number of data points:
There are 7 data points.

STEP 5

Calculate the mean by dividing the sum by the number of data points:
xˉ=427 \bar{x} = \frac{42}{7}
xˉ=6 \bar{x} = 6
The mean of the data set is:
6 \boxed{6}
