The relative frequency for the third class, 60 - 69 is equal to 12%.
<h3>What is a class width?</h3>In a frequency distribution table, a class width can be defined as the difference between the upper (maximum) and lower (minimum) boundaries of any class in a data set. This ultimately implies that, all classes must all have the same width in a frequency distribution table.
<h3>What is a frequency table?</h3>A frequency table can be used to graphically represent the frequencies or relative frequencies that are associated with a categorical variable.
<h3>How to calculate the relative frequency for the third class, 60 - 69?</h3>First of all, we would determine the total number of frequency as follows:
Total frequency = 12 + 11 + 6 + 10 + 11
Total frequency = 50.
Mathematically, relative frequency can be calculated by using this formula:
Relative frequency = class frequency/total frequency × 100
Relative frequency = 6/50 × 100
Relative frequency = 0.12 × 100
Relative frequency = 12%.
