dentify the outlier in the data set 6, 9, 3, 2, 10, 138, 13. Then find the mean and median with and without the outlier. Explain how the outlier affects the data set. If necessary, round your answers to the nearest tenth.
2. The range is most useful when you need to show the spread of the data. In complete sentences, explain whether this statement is true or false, and why.
3. The table shows the number of students who entered the science fair in the last seven years. Identify the outlier of the data set. Compare the mean and median of the data sets with and without the outlier. Explain how the outlier affects the data set.

4. The monthly rents for five apartments advertised in a newspaper were $670, $670, $790, $1550, and $810. Use the mean, median, mode, and range of the rents to answer the following question: Which measure of central tendency best described the advertised rents? Calculate the four measures of central tendency and provide two to four sentences supporting the answer.
5. The mode is the number or numbers that occur most frequently in a set of data.
In complete sentences, explain whether this statement is true or false, and why. Provide an example of a data set with a mode and a data set without a mode.
