Step-by-step explanation:

We are given a set of the data as:

922161216    102216178    2018102025  6141014    20

on arranging this data in ascending order we have:

6    8     9    10    10    10    12    14   14    16    16    16    17     18      20    20    20   22   22    25

Hence, the lowest value is: 6

The highest value is: 25.

Now the data is divided into 3 quartiles.

Median () is defined as the central tendency of a data i.e. the middle value of the data.

Hence the median here will lie between: 16 and 16.

Hence the median () is 16.

Now the lower set of data is:

6    8     9    10    10   10    12    14   14  

Hence, the lower quartile() is the median of the lower set of data i.e. the middle term in the following lower set of data.

Hence, the lower quartile () is: 10

Similarly the upper set of data is given as:

16    17     18      20    20    20   22   22    25

Hence, the third quartile () is the median of the lower set of data i.e. the middle term in the following lower set of data.

Hence, the third quartile () is: 20
