Comparing Mean and Range of Two Classes

What are the mean and range for each class?

Class A: Mean- 422/5= 84.4. Range: 94-74=20

Class B: Mean- 418/5= 83.6. Range: 88-80 = 8

The mean and range for class A are 84.4 and 20 while the mean and range for class B are 83.6 and 8.

Reflecting on the comparison of mean and range between Class A and Class B highlights some interesting insights into the performance of the students in each class. While both classes have similar mean scores, Class A has a wider range of scores compared to Class B. It raises questions about the consistency of performance within each class.

How to calculate the mean?

It should be noted that mean simply means average. It's the addition of the numbers divided by the total numbers.

In this case, the computation will be:

Class A: Mean = 422/5= 84.4.

Range: 94-74 = 20

Class B: Mean = 418/5 = 83.6.

Range= 88-80 = 8

Calculating the mean is essential in understanding the central tendency of a set of data, providing a useful summary of the data points.
