Question

a survey asked a group of people the size of their households. the results are shown in the frequency distribution. what is the mean of the frequency distribution?

Answer 1

we have the following:

`m=(f_1+f_2+f_3+f_4+f_5)/(5)`

replacing:

`\begin{gathered} m=(4+12+6+2+1)/(5) \\ m=(25)/(5) \\ m=5 \end{gathered}`

therefore, the mean is 5
