Based on the calculations, the mean for this data set is equal to 129.5.
A mean is also known as average and it simply refers to a ratio of the sum of the total number in a data set to the frequency of the data set.
Mathematically, the mean for this data set would be calculated by using the following formula:
Mean = [F(x)]/n
For the total number of data, we have:
F(x) = 138 + 142 + 105 + 112 + 108 + 134 + 106 + 181 + 164 + 105
F(x) = 1,295.
Substituting the parameters into the formula, we have:
Mean = [F(x)]/n
Mean = [1,295]/10
Mean = 129.5.
