1.Arithmetic mean

2.Median

3.Range

4.Mode

5.Second decile

A1, 2, 3

B1, 2, 4 ✓ Correct

C1, 2, 4, 5

D1, 2, 3, 4, 5

Correct answer: (B) 1, 2, 4

Explanation

The measures of central tendency are Statement 1, 2 and 4.

Central tendency describes a typical central value of a data set.

Arithmetic mean (1), median (2) and mode (4) each locate such a centre.

Range (3) measures spread, not a central value.

The second decile (5) is a positional partition value, not a central measure.
