Answer:
(a) Mean = 42.64
(b) Median= 37
(d)Midrange =39
Step-by-step explanation:
Given data,
60,31,19,55,21,37,94,62,41,15,34
(a)
Mean: Mean is the ratio of all observation to the total number of observation.
=42.64
(b)
To find the mean of given data,first we have to arrange the date in ascending order or descending order.
Median: Median is middle term of the observation.
15,19,21,31,34,37,41,55,60,62,94
n = Total number of observation=11
= 6th term
=37
(c)
Mode is a observation which repeat maximum time.
Here all observations have only one one frequency, so it is multimodel data.
(d)
Midrange: The substraction of first quartile from third quartile.
First quartile: The mid-value of lower half.
Lower portion :15,19,21,31,34
Third quartile: The middle value of upper half.
upper half: 41,55,60,62,94
Mid range =
=60-21
=39
