8) Find the mean, median, mode to the
the given dalle
25, 31, 15, 20, 22, 12. Also find the range
Answers
Answer:MEAN:115
MEDIAN:17.5
MODE:31
RANGE:19
Answer:
Mean: 20.83
Median: 21
Mode: All numbers
Range: 19
Step-by-step explanation:
First of all we would arrange these numbers in ascending order - 12, 15, 20, 22, 25, 31.
Mean = sum of all observations/total no of observations
= 125/6
= 20.83
Median
As total no. of observations is even so median would be the mean of (n/2)th term and (n/2+1)th term. Here n = 6.
n/2 = 6/2 = 3
n/2+1 = 6/2+1 = 6+2/2 = 8/2 = 4
So the median would be the mean of 3rd and 4th term.
= 20+22/2
= 42/2
= 21
Mode = The observation occuring most no. of times. As here all the observations are occuring equal no. of times, so all numbers are mode.
Range = Difference of largest and smallest value
= 31-12
= 19
