Sample Questions

1multiple choice

If the class interval is 15-25, what is the class mark?

Show answer

20

Class mark = (Lower limit + Upper limit) ÷ 2 = (15 + 25) ÷ 2 = 40 ÷ 2 = 20. Common mistake: Taking one of the limits instead of average.

2multiple correct

Which of the following are measures of central tendency? (Select all correct options)

Show answer

Mean, Median, Mode

Mean, Median, and Mode are the three main measures of central tendency that represent the center of data. Range measures spread, not center. Frequency shows occurrence count.

3multiple choice

Calculate the range of the data: 15, 8, 22, 11, 19, 6, 25

Show answer

19

Range = Highest value - Lowest value = 25 - 6 = 19. First identify highest (25) and lowest (6) values, then subtract. Common mistake: Adding instead of subtracting.

4multiple choice

In a class of 30 students, if 12 students scored 80 marks, 10 students scored 85 marks, and 8 students scored 90 marks, what is the mean score?

Show answer

84

Total marks = (12×80) + (10×85) + (8×90) = 960 + 850 + 720 = 2530. Mean = 2530 ÷ 30 = 84.33 ≈ 84. Common mistake: Taking simple average of scores without considering frequencies.
