Answer

Following steps are involved in construction of a discrete frequency distribution:

Arrange the series in ascending or descending order: First of all, arrange the raw data in ascending or descending order.
Make as many classes as many are values of variable: Place all values of the variable in the first column of the series beginning with the lowest and giving to the highest.
Determine Frequency of each value: To determine frequency of a class, count, how many times a value is repeating itself. For counting, also make a column of tally bars before frequency. A vertical line is put for each repetition and after for five four lines are intersected like this.
Place Frequencies: Count the bars. Write it in front of each class in frequency column.
Check Mathematical Accuracy: Total the frequency column to verify if sum total of frequencies is equal to number of total observations.
