Question

We have provided simple data set for you to practices the basics of finding measures of center. For each data set determine the:

a) Mean

b)Median

c) Mode.

The given data set is:$4,2,0,2,2$.

Short answer

a) Mean$=2$

b) Median$=2$

c) Mode$=2$

Step-by-step solution

Step 1. Given information.  

The given data is$4,2,0,2,2.$

Step 2. Mean of the data.  

Mean$=\frac{Sumofobservation}{Numberofobservation}$

$$\begin{gathered} =\frac{4+2+0+2+2}{5} \\ =\frac{10}{5} \\ =2 \end{gathered}$$

Step 3. Median of the data.  

Arrange the data in increasing order $0,2,2,2,4$.

The number of observation is $5$.

The median is the observation exactly in the middle of the ordered list.

Thus, the median is$2$.

Step 4. Mode of the data. 

The entry occurring with the greatest frequency is$2$.
