Blood Group Distribution Among Nursing Students at LMMU

Nursing students at LMMU were asked to state their blood groups as being O, A, B, or AB. The responses provided by a sample of 20 students are: O AB O B AB O A O B O B A O AB A B O AB O AB Illustrate the above data on a (i) Frequency table (ii) Bar chart (iii) Pie chart

To illustrate the blood group data provided by the nursing students at LMMU, we will first create a frequency table, then a bar chart, and finally a pie chart.

(i) Frequency Table

Let's first count the occurrences of each blood group from the provided data:

• Blood Group O: 7
• Blood Group A: 3
• Blood Group B: 5
• Blood Group AB: 5

Now, we can create the frequency table:

(ii) Bar Chart

To create a bar chart, we can represent the frequency of each blood group visually. Below is a textual representation of how the bar chart would look:

Blood Group Frequency
O   | ███████
A   | ███
B   | █████
AB  | █████

In a graphical representation, each bar would be proportional to the frequency of each blood group.

(iii) Pie Chart

To create a pie chart, we need to calculate the percentage of each blood group based on the total number of students (20).

• Percentage of O = (7/20) * 100 = 35%
• Percentage of A = (3/20) * 100 = 15%
• Percentage of B = (5/20) * 100 = 25%
• Percentage of AB = (5/20) * 100 = 25%

Now, we can represent this data in a pie chart format. In a graphical representation, the pie chart would be divided into sections based on these percentages:

• O: 35%
• A: 15%
• B: 25%
• AB: 25%

Summary

1. Frequency Table:

   • O: 7
   • A: 3
   • B: 5
   • AB: 5

2. Bar Chart: (Textual representation)

   O   | ███████
   A   | ███
   B   | █████
   AB  | █████
   

3. Pie Chart: (Descriptive)

   • O: 35%
   • A: 15%
   • B: 25%
   • AB: 25%

For actual graphical representations of the bar chart and pie chart, you would typically use software like Excel, Google Sheets, or any data visualization tool to create them visually.
