Find the mean of the data set, if necessary, round to the nearest tenth
To find the mean of a data set, you need to follow these steps:
1. Add up all the values in the data set.
2. Count the number of values in the data set.
3. Divide the sum of the values by the number of values.
Let's say you have the following data set: 5, 7, 8, 9, 10.
1. Add up all the values: 5 + 7 + 8 + 9 + 10 = 39.
2. Count the number of values: There are 5 values in the data set.
3. Divide the sum of the values by the number of values: 39 / 5 = 7.8.
Therefore, the mean of the data set is 7.8 when rounded to the nearest tenth.
