What this printable includes
Find four summaries for six small data sets: mean, median, mode and range. The carefully chosen sets have whole-number means and a single mode, keeping the first practice focused. Each item has room for labeled answers, with a separate key for checking.
How to use the page
Sort the values before finding the median, and remember that repeated values still count as separate observations. Add all values and divide by the number of values for the mean. The mode is the most frequent value. Subtract the smallest value from the largest to find the range.
Review and adapt
Label each result rather than writing four unexplained numbers. For an even number of values, the median is the mean of the two middle values. Other data sets can have no mode or multiple modes, but those cases are not included here. These summaries describe the supplied numbers and do not explain their cause.
