Question

Table 2 shows frequency distribution for variable p.Table 2: Frequency distribution for pa) Calculate the mean value for p.b) Calculate the median value for p.c) Find out the mode value for p.

Answer 1

The mean of a distribution is given by

Consider the table below

Then the mean of p is

The median is the middle value after arrangement in ascending or descending order

The the median is

`\begin{gathered} \text{Meadian=}(\sum f)/(2)=(32)/(2)=16th\text{ position } \\ \end{gathered}`

The locating the 16th position, we have two values
