Question

Construct a frequency distribution and a relative frequency histogram for the data set using five classes. Which class has the greatest relative frequency and which has the least relative​ frequency?

Answer 1

Answer:

Class 3rd has the highest relative frequency and class 4th has the lowest relative frequency.

Step-by-step explanation:

To calculate class width we use the formula given below;

Class Width = Maximum Value - Minimum Value

                                 Number of Classes

Class Width :  $\frac{10 - 1}{5}$ = 2 approximately.

Relative frequency is obtained by counting each class frequency.

Class            Frequency                 Relative Frequency

1 - 2                     7                                     0.1944

3 - 4                    8                                     0.2223

5 - 6                   10                                    0.2778

7 - 8                    4                                     0.1111

9 - 10                  7                                      0.1944

Class 3rd has the highest relative frequency and class 4th has the lowest relative frequency.
