Question

Nine people in a class participated in a survey on their shoe sizes. The sizes obtained by them were recorded as follows. 8, 10, 9, 10, 6.5, 6.5, 7.5, 9, 6.5. Find the mode and median of the data. *

Answer 1

Answer:

mode= 6.5

median= 8

Step-by-step explanation:

Mode can be identified easily by repeating observations. In a set of observations, the observation repeated more number of times is mode. In the above observations, 6.5 is repeated more times. So it is the mode.

Median depends on number of observations. Let no.of observations is 'n'. If 'n' is odd, then median= (n+1/2)th observation. If 'n' is even, then median= arithmetic mean of (n/2)th and (n/2+1)th term.
