Answer 2

Frequency Distribution:

• Frequency distribution is a graphical or tabular form of representing the number of observations in a given data.
• It can be represented as an individual observation or observation within a given interval.
• It is used to keep a count of the occurrence of each observation.
• There are three types of frequency distribution: cumulative frequency, relative frequency, and relative cumulative frequency.

Step-by-step explanation:

The data given is as follows:

22, 24, 20, 18, 13, 15, 15, 18, 18, 20, 24, 22, 24, 25, 25, 21, 19, 19, 18, 24

Arranging the given data in ascending order:

13, 15, 15, 18, 18, 18, 18, 19, 19, 20, 20, 21, 22, 22, 24, 24, 24, 24, 25, 25

The frequency distribution table for the data is as follows:

Data   Frequency

13              1

15             2

18             4

19             2

20            2

21              1

22            2

24            4

25            2
