How are measures of central tendency affected by outliers?
Look below :)
When a outlier is present it can effect the shape of the graph, if we have outliers to the right of the graph. These outliers are causing the mean to increase, but if we have outliers to the left of the graph these outliers are dragging down the mean. This causes a conflict because the mean no longer provides a good representation of the data, alternatively we would much rather use the median. The median on the other hand is less likely to be affect by outliers.
