5-68.

Remember that the mean is the average, the median is the middle number, and the mode is the most repeated number. It helps to put the data in order from least to greatest!

Here, there are no changes to any of the measures of central tendency.

Using the information from part (a), do you notice any changes in the data?

Everything changes in part (b). The mean becomes 9.2 and the median is now 10. Did you find the new mode?

Do you see any patterns in parts (a) and (b)? Do you think adding data will always change the measures of central tendency (mean, median, and mode)?
