Sample Questions

1multiple correct
3 marks

A dataset has values 12, 15, 15, 18, and 20. Find the median and the mode together.

Show answer

Median = 15, Mode = 15

The data are already in numerical order. The middle value is 15, so the median is 15. The value 15 occurs most frequently, so the mode is also 15.

2multiple correct
3 marks

A dataset has values 3, 3, 3, 3, and 3. Find the variance condition and the standard deviation condition.

Show answer

Variance is zero, Standard deviation shows no dispersion from the mean

A variance of zero means all values are identical. When all values are the same, there is no variation from the average mean, so standard deviation is also zero.

3multiple correct
3 marks

A class has data values 2, 4, 6, 8, and 10. Find the mean and the median.

Show answer

Mean = 6, Median = 6

Mean = (2 + 4 + 6 + 8 + 10) / 5 = 30 / 5 = 6. The ordered data have 6 as the middle value, so the median is 6.

4multiple correct
3 marks

A dataset has values 1, 2, 2, 3, 3, 3. Identify all correct statements about its mode.

Show answer

The mode is 3, The dataset has one mode

The value 3 appears most frequently. Since only one value appears most often, the dataset has one mode.
