Question

Data are collected about the amount of time, in minutes, each member of a dance troupe spend practicing. How does a single outlier change the median of the collected data? (4 points)


A single outlier doubles the value of the median.

A single outlier does not affect the median.

A single outlier causes the value of the median to move slightly toward the outlier.

A single outlier causes the value of the median to move slightly away from the outlier.

Answer 1

The median is the 'middle' number when the data is arranged in ascending order. if there are an even number of data the median is the mean of the middle 2 numbers.
Adding an outlier will alter the total of numbers and will alter the value of the median.
