The table below shows the number of messages exchanged on the smart phones of 14 students over a single month. The data has also been plotted on a dot plot. Are there any outliers in this data set? If so, specify the value or values of these outliers.

If we’re just given a table of data, the outlier isn’t always apparent. One benefit of a graph like this is we’re able to see the data points in relation to each other. We can very quickly see that we have one data point that is far away from most of the others. The data points here primarily fall between 2800 and 5500 with only one point falling outside this range. On the graph, we can identify this as the data point 9754. In this data, there is one outlier, and it’s 9754.
