Index Numbers and Time Based Data

Question:

For the given five values 13, 24, 17, 31, 45, the three years moving averages are.

Options:

18, 21, 33

18, 24, 31

15, 27, 31

17, 24, 32

Correct Answer:

18, 24, 31

Explanation:

The correct answer is Option (2) → 18, 24, 31

$\text{Data: } 13, 24, 17, 31, 45$

$\text{First average} = \frac{13+24+17}{3} = \frac{54}{3} = 18$

$\text{Second average} = \frac{24+17+31}{3} = \frac{72}{3} = 24$

$\text{Third average} = \frac{17+31+45}{3} = \frac{93}{3} = 31$

The three-year moving averages are $18, 24, 31$.
