Answer:
mean = 85.5
median = 90
mode = 95
range = 35
Step-by-step explanation:
First arrange the data in ascending order:
60 75 75 90 90 95 95 95 95
Mean is the average number found by adding all of the numbers together and dividing by the number of terms in the set.
[tex] = \frac{60 + 75 + 75 + 90 + 90 + 95 + 95 + 95 + 95}{9} [/tex]
[tex] = \frac{770}{9} [/tex]
=85.5
Median is the middle number of the set: (9+1) ÷2 = 5th term.
60 75 75 90 90 95 95 95 95
therefore the median is 90
The mode is the number that is repeated more often than any other, so 95 is the mode.
The range = the largest value - the smallest value
= L-S = 95-50
= 35
Therefore the range is 35.
