Question

The following frequency distribution, X: 12 17 24 36 45 48 52 F : 4 0 7 8 9 6 3 Is classified as what?​

Answer 1

Answer:

The frequency of occurrence of each class is given by the values in the F column, corresponding to the respective classes in the X column. For example, the frequency of Class 1 is 4, which means that there are 4 data points in the X column that fall in the interval 10.5 - 19.5.

Explanation:

The given frequency distribution is classified as a grouped frequency distribution.

In a grouped frequency distribution, the data is divided into intervals or classes, and the frequency of occurrence of each class is recorded. In this case, the classes are:

Class 1: 10.5 - 19.5

Class 2: 19.5 - 28.5

Class 3: 28.5 - 37.5

Class 4: 37.5 - 46.5

Class 5: 46.5 - 55.5

The class boundaries are chosen such that each data point falls into exactly one class, and there are no gaps or overlaps between the classes.

The frequency of occurrence of each class is given by the values in the F column, corresponding to the respective classes in the X column. For example, the frequency of Class 1 is 4, which means that there are 4 data points in the X column that fall in the interval 10.5 - 19.5.
