# Relative Frequency Distribution Table

TopFrequency can be defined as how many times something occurs or in other words it can also be defined as summation of happening of values within a special Set and frequencies can be used to make a frequency table by counting them. Frequency distribution can also be defined as an arrangement of parameters (values or number etc.) which are used in a sample by one or more than one variables. Relative frequency distribution can be defined as Ratio of frequency of a particular group to total number of frequencies of that group. Relative frequency distribution is normally expressed in form of Percentage. In relative Frequency Distribution Table frequencies are expressed in form of table. How many times an item is repeated? It can only be decided by using the concept of frequency distribution table.

Let’s take an example to understand relative frequency distribution table.
Marks of 100 students are shown below:
Marks No. of students (an)
55 – 60 8
61 – 65 12
66 – 72 15
73 – 80 9
81 – 90 5

Relative frequency distribution table can be drawn as shown below:

Marks No. of students (an) Relative frequency
55 – 60 8 (8/100) * 8% = 0.08
61 – 65 61 (61/100) * 61% = 0.61
66 – 72 15 (15/100) * 15% = 0.15
73 – 80 11 (11/100) * 9% = 0.11
81 – 90 5 (5/100) * 5% = 0.05
Here total ∑an = 100.
Above table is representing the relative frequency distribution table and it can be concluded from above table that frequency of a group describes the number of times group is repeated in total number of items. Here in the above example, total number of students is 100.
