fine the mean of the data set if necessary round to the nearest tenth
To find the mean of a data set, you need to sum up all the values in the data set and divide it by the total number of values.
Here are the steps to find the mean of a data set:
1. Start by adding up all the values in the data set.
2. Count the total number of values in the data set.
3. Divide the sum by the total number of values.
4. Round the result to the nearest tenth, if necessary.
Let's say we have the following data set: 5, 10, 15, 20, and 25.
1. Add up all the values: 5 + 10 + 15 + 20 + 25 = 75.
2. Count the total number of values: There are 5 values in the data set.
3. Divide the sum by the total number of values: 75 ÷ 5 = 15.
4. Since the result is already rounded to the nearest whole number, we don't need to make any additional rounding.
Therefore, the mean of the given data set is 15.
