Answer:
Mean = 24.3
Median = 23.5
Step-by-step explanation:
The data given here is an ungrouped data.
Mean(Average) of the given data = Sum of the observations / Number of
observations
= (14 + 15 + 18 + 21 + 22 + 25 + 27 + 31 + 34 + 36)/ 10
= 243/10
Mean = 24.3
To find the median of the date,
Arrange the data in ascending order.
14, 15, 18, 21, 22, 25, 27, 31, 34, 36
Median = Average of (n/2)th term and (n/2 + 1) th term.
n/2 th term = 10/2 = 5th term = 22
n/2 +1 th term = 10/2 + 1 = 5+1 = 6th term = 25
Now, median = average of the 2 terms = (22+25)/2 = 47/2 = 23.5
Median = 23.5
