Question

Calculate the mean for the following data points 25.4, 19.5, 17.28 19.06, 22.3. 23.9

Answer 1

To calculate the mean (average) of the given data points, you need to follow these steps:

1. **Sum the data points**:
\[
25.4 + 19.5 + 17.28 + 19.06 + 22.3 + 23.9
\]

2. **Calculate the sum**:
\[
25.4 + 19.5 = 44.9
\]
\[
44.9 + 17.28 = 62.18
\]
\[
62.18 + 19.06 = 81.24
\]
\[
81.24 + 22.3 = 103.54
\]
\[
103.54 + 23.9 = 127.44
\]

3. **Count the number of data points**:
There are 6 data points.

4. **Divide the sum by the number of data points**:
\[
\text{Mean} = \frac{127.44}{6} \approx 21.24
\]

So, the mean of the data points 25.4, 19.5, 17.28, 19.06, 22.3, 23.9 is approximately **21.24**.
