Question

A die was thrown 15 times and the outcomes recorded were 5, 3, 4, 1, 2, 6, 4, 2, 2, 3, 1, 5, 6, 1, 2 Find the mean, median and mode of the data.

Answer 1

Arranging the data in ascending order, we get
1, 1, 1, 2, 2, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6

Since, observations are odd in number,

∴ Median = Middle most observation i.e., 8th observation = 3

Since, 2 occurs most frequently i.e., 4 times

∴ Mode = 2
