Question

Identify outlier in following list. Then find mean/median of list with/without outlier. 10, 4, 20, 5, 11, 150, 7
a.Outlier = 10
Mean with outlier = 29.6
Median with outlier = 10
Mean without outlier = 44.1
Median without outlier = 10.5
b.Outlier = 10
Mean with outlier = 10
Median with outlier = 29.6
Mean without outlier = 8.5
Median without outlier = 9.5
c.Outlier = 150
Mean with outlier = 9.5
Median with outlier = 8.5
Mean without outlier = 29.6
Median without outlier = 10
d.Outlier = 150
Mean with outlier = 29.6
Median with outlier = 10
Mean without outlier = 9.5
Median without outlier = 8.5

Answer 1

Which one do you think is the outlier?

Answer 2

150

Answer 3

So, it's C or D. Median is easiest to figure out of the remaining things. C says the median without outlier = 10. D says median without outlier = 8.5. Do you know how to find the median? What do you do first to find the median?

Answer 4

Put Them In Order..?

Answer 5

Yes!

Answer 6

4 5 7 10 11 20

Answer 7

Dont You Add 7 And 10 Now...?

Yes. Add 7 and 10 and divide what you get by 2....(to average them)

Answer 9
