Question

Medians of following data sets are:

Set I -- {3, 7, 2, 11, 8}

Set II -- {-1, 0, 1, 7, 11, 4}

• A. 7
• B. 2.5
• C. 7.5
• D. 2

Answer 1

Answer: (A), (B)

The correct options are
A 7
B 2.5

Arranging both sets in ascending order, we get:

Set I - {2, 3, 7, 8, 11} - Middle term = 7

Set II - {-1, 0, 1, 4, 7, 11} - Middle terms = 1, 4

∴ Median of set - I = Middle term = 7

Median of set - II = $\frac{\text{Sum of middle terms}}{2}$ = $\frac{1+4}{2}$ = 2.5
