Data are collected about the amount of time, in minutes, each member of the lacrosse team spends practicing. How does a single outlier change the mean of the collected data? A single outlier causes the value of the mean to move slightly toward the outlier. A single outlier causes the value of the mean to move slightly away from the outlier. A single outlier does not affect the value of the mean. A single outlier doubles the value of the mean.
Question
Answer:
the mean is affected by an outlier...lets find out how...example : (2,3,4,5,30)
the outlier is 30
the mean is :(2 + 3 + 4 + 5 + 30) / 5 = 44/5 = 8.8
now lets take out the outlier of 30...and find the mean
(2 + 3 + 4 + 5) / 4 = 14/4 = 3.5
therefore, a single outlier can cause the value of the mean to move slightly towards the outlier
