PERCENTAGE FREQUENCY OF A CLASS INTERVAL

Percent frequency of a class interval may be defined as the ratio of class frequency to the total frequency, expressed as a percentage.

To have better understanding on percentage frequency of a class interval, let us consider the frequency distribution given below.

In the above frequency distribution of weights of 36 students, the percentage frequencies for the first two class intervals are 300/36 and 400/36 respectively.

Apart from percent frequency of a class interval, let us look at some other important terms associated with a frequency distribution.

Relative Frequency

Relative frequency of a class interval may be defined as the ratio of the class frequency to the total frequency.

In the above frequency distribution of weights of 36 students, the relative frequencies for the first two class intervals are 3/36 and 4/36 respectively.

It is quite obvious that whereas the relative frequencies add up to unity, the percentage frequencies add up to one hundred.
