Zahra was given two data sets, one without an outlier and one with an outlier. Data without an outlier: 15, 19, 22, 26, 29 Data with an outlier: 15, 19, 22, 26, 29, 81 How is the median affected by the outlier?

Without the outlier, the middle value of 15, 19, 22, 26, 29 is 22. With 81 added, there are six values, so the median is the average of the two middle values: (22 + 26) ÷ 2 = 24. The median rises by only 2, so the outlier slightly affected it; it did not make the median much higher.
