Question:
The mode of given data 15, 14, 19, 20, 14, 15, 16, 14, 15, 18, 14, 19, 15,17 and 15 is
(a) 14
(b) 15
(c) 16
(d) 17
Thinking Process
Find the maximum number of repeated observation to get the value of mode.
Solution:
(b) We first arrange the given data in ascending order as follows 14, 14, 14, 14, 15, 15, 15, 15, 15, 16, 17, 18, 19, 19, 20 From above, we see that
15 occurs most frequently i.e., 5 times.
Hence, the mode of the given data is 15.
