Anyone know this?
The data set shows the test scores for 7 students in a math class.
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.
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.
