Question

The data set shows the results of a survey conducted on a video game usage. The Average time each student surveyed spent per day playing video games in minutes. Help the analyst find the mean,median and mode of the set show all work .

Answer 1

Given data:

85, 75, 90, 10, 130, 78, 162.

To find mean, median and mode:

First, let us write the given data in the ascending order.

So, we have

10, 75, 78, 85, 90, 130, 162.

Mean:

We know that,

Mean = Sum of the observations/ total number of observations.

So that,

`\begin{gathered} \text{Mean}=(10+75+78+85+90+130+162)/(7) \\ =(630)/(7) \\ =90 \end{gathered}`

Thus, Mean is 90.

Median:

Median is nothing but the middle value of the data set.

So, here the median is 85.

Mode:

The mode is the number that is repeated most often in the given set of data.

But here, all the numbers in this list appear only once.

So, there is no mode.
