Question

Does anyone know how to solve this ?

Answer 1

Amit 88
Traci 76
Lee 54
Barry 83
Amy 92
Ling 95
Rachael 80
When calculating the average score for the class, the teacher claims that she should exclude Lee's test score because he was absent the entire week before the test.

Evaluate this claim by selecting the statement that best reflects why the reasoning is either correct or flawed. (1 point)

Question
options:
1) The reasoning is flawed. Lee's test score is not an outlier and removing it would decrease the mean.
2) The reasoning is correct. Lee's test score is an outlier and excluding it would increase the mean.
3) The reasoning is flawed. Lee's test score is an outlier, but there is no evidence that this test score is not typical.
4) The reasoning is correct. Lee's test score is not an outlier, but the value should not be included anyway due to the fact that he was absent.

Answer 2

Ling 95
Amy 92 - Higher Quartile
Amit 88
Barry 83 - Median
Rachael 80
Traci 76 - Lower Quartile
Lee 54

InterQuartile Range 92-76 = 26
Distance to Lee 76-54 = 22

Is Lee an outlier?

Answer 4

You must decide if it's REALLY an "outlier". What is the definition?

Answer 5

Def of outlier a person or thing situated away or detached from the main body or system.
"less accessible islands and outliers"

Too vague. With numerical data, there is a much more objective definition.
