Step 1

Frequency distribution:

The number of times each value of X repeats is the frequency of that particular event. Frequencies will be calculated by using the tally mark.

Discrete random variable:

If the variable X takes finite or countable values, then the variable X is said to be discrete.

Conditions to construct a discrete frequency distribution:

  • The number times a specified value of X repeats is the frequency of that particular value of
  • The sum of frequencies of all the values of X must be equal to total number of observations.
  • The probabilities of all the values of the variable X must lie between 0 and 1.
Step 2

Construct the frequency distribution for the data of patient’s blood type.

Consider that the variable X represents the patient’s blood type.

Here, the variable X takes the values A, B, AB and O.

Here, A is a blood type , and A is repeated 7 times in the dataset.

Therefore, the frequency of the blood type A is 3.

Similarly, the frequencies of all the remaining blood types have to be calculated.

The frequency distribution table for the data of patient’s blood type is obtained below:

Step 3

Construct a pie chat for the data of patient’s blood type.

Here, EXCEL software is used to construct pie chart.

Software procedure:

Step-by-step procedure to draw the pie chart using EXCEL software:

  • In Excel sheet, enter X = Patient’s blood type in one column and Percentage in another column.
  • Select the data and then choose Insert > Cha...
