The measures of center can summarize a set of data and help you to understand the data set.
Using a visual display of data to extract information such as mean, median and mode is an important skill and one that will provide a foundation for upcoming statistical concepts. Students should recognize that the very shape of the distribution in a box plot, histogram or a dot plot can also show patterns and trends as well as any outliers.
