Find the mean of the following scores: 8, 12, 15, 10, 20, 18, 14
What is the median of the data set: 7, 3, 9, 12, 5, 8, 11?
In a frequency table, if the frequency of class 10-20 is 8 and class 20-30 is 12, what is the cumulative frequency for class 20-30?
Find the mode of the following data: 4, 6, 4, 8, 4, 9, 6, 4
Sample Questions
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.
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.
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.
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.
