Sample Questions

1multiple correct

Which methods can be used to calculate mean for grouped data?

Show answer

Direct method, Short-cut method, Step-deviation method

The three methods for calculating mean of grouped data are: 1) Direct method using Σfx/Σf, 2) Short-cut method using assumed mean, 3) Step-deviation method using class interval.

2multiple choice

In short-cut method for mean, if A = 25 and Σfd/Σf = 3, what is the mean?

Show answer

28

Using short-cut method: Mean = A + (Σfd/Σf) = 25 + 3 = 28, where A is assumed mean and d = x - A.

3multiple choice

Calculate the mean of: 12, 15, 18, 21, 24

Show answer

18

Mean = (12 + 15 + 18 + 21 + 24)/5 = 90/5 = 18.

4multiple choice

Find the median of: 1, 3, 5, 7, 9, 11

Show answer

6

For 6 observations (even), median = (3rd term + 4th term)/2 = (5 + 7)/2 = 12/2 = 6.
