Question

The median of 11 observations is 10. The number of possible observations in the data which are less than 10 is

(a) 5 (b) 6 (c) 3 (d) 10

Answer 1

Median divides the data into two equal parts. Since, the number of observations is 11, so
after arranging in increasing or decreasing order, the number of observations to the left
of the median is five.
Thus, the required number of observations is 5.
Hence, the correct option is (a).
