The mean of the set of data is <u>65</u>.
<em><u>Given the following </u></em><em><u>data set:</u></em><em><u> </u></em>
34, 48, 52, 61, 76, 76, 61, 84, 61, 39, 83, 61, 79, 81, 56, and 88
<em><u>Recall</u></em>:
- The mean of any set of data is the average of all the data values in the given data set.
- It is calculated by summing all the data values in the data set divided by the number of data values in the data set
<em>Let's solve for the </em><em>mean</em>:
- Mean = sum of all data set / number of data set
<em>Thus</em>:
- sum of all data set =
- Number of data set = 16
Therefore, the mean of the data set given is 65.
