Following are the marks obtained (out of 10) by the students in a test: 8, 9, 3, 2, 3. Determine the range of the above data.

• A. 5
• B. 3
• C. 9
• D. 7

Hint:

The range is a measure of dispersion, showing the spread of data values.

Range = Maximum Value − Minimum Value

In this case:
Range = 9 − 2 = 7
