Question:

Jin Ya take the bus across town to school each morning last week he timed his trips and found that the time varies day today the time in minutes or listed below:

10 15 11 13 11

If you had to use one number to tell someone how long it took Jin Ya to get to school, what would you say?

Answer:

11 minutes or 12 minutes

Explanation:

Given:

10 15 11 13 11

Required

Determine one number that summarizes the 5 numbers

First, one can use the mean to get the summary of the numbers.

The mean is calculated as:

`Mean = (Sum\ of\ observation)/(Number\ of\ observation)`

`Mean = (10 + 15 + 11 + 13 + 11)/(5)`

`Mean = (60)/(5)`

`Mean = 12`

Another number that summarizes the numbers is the mode of the distribution.

`Mode = Highest\ Occurring\ Value`

So, in this case:

`Mode = 11`

Hence, you can either use 11 minutes or 12 minutes.
