As per the given data,
9, 5, 8, 9, 9, 7, 8, 9, 8
Arranging the numbers in numerical order
5, 7, 8, 8, 8, 9, 9, 9, 9
Since there is odd number of numbers, middle number is the median of the given data
⇒ Median = 8
The value which appear mostly is considered as mode, as 9 is repeated 4 times.
⇒ Mode = 9
Mean = (9 + 5 + 8 + 9 + 9 + 7 + 8 + 9 + 8)/9 = 8
∴ Median, mode and mean = (8, 9, 8)
9, 5, 8, 9, 9, 7, 8, 9, 8
