Answer:
(a) Mean = 55.9
(b) Median = 59
(c) Mode = No mode
(d) Midrange = 93
Explanation:
(a) Mean
The formula for finding mean of an ungrouped data = Σx/n
Where
Σ is the sum of all the data
n is the number of data in the set
Therefore,
Σx=615
n = 11
Mean = 615/11
=55.9
(b) Median
Median is the middle number after arranging the set of data in either ascending or descending order.
By arranging the numbers, the middle is 59 which is the Median
(c) mode
Mode is the number that occurs most in a set of data.
From the given set of numbers, all the numbers appear once. Therefore, there is no mode
(d) Midrange
This is the difference between the biggest and the smallest number in a set of data.
Therefore,
the midrange = 97-4
=93
