Ivan was given two data sets, one without an outlier and one with an outlier. data without an outlier: 108, 113, 105, 118, 124, 121, 109 data with an outlier: 108, 113, 105, 118, 124, 121, 109, 61 how is the median affected by the outlier?

Median is decreased by the outlier or Outlier made median lower.

Step-by-step explanation:

First we calculate median of the data without an outlier:

Data in Ascending or increasing order ,

105 , 108 , 109 , 113 , 118 , 121 , 124

Now there are 7 terms so

Median = = 4th term = 113

Now we find median of the data with outlier:

Data in ascending or descending order,

61 , 105 , 108 , 109 , 113 , 118 , 121 , 124

here no of terms are 8.

So, Median =

                   =

                   = 111

So, Median is decreased by the outlier or Outlier made median lower.
