Data Data is information that has been collected to represent real life situations, usually in number form.
Mean The mean of a data set is the average of the data set. The mean is found by calculating the sum of the values in the data set and then dividing by the number of values in the data set.
Median The median of a data set is the middle value of an organized data set.
Mode The mode of a data set is the value or values with greatest frequency in the data set.
Stem-and-leaf plot A stem-and-leaf plot is a way of organizing data values from least to greatest using place value. Usually, the last digit of each data value becomes the "leaf" and the other digits become the "stem".
