- 4. / the middle number of a set of numbers when the numbers are arranged from least to greatest, or the mean of two middle numbers when the set has two middle numbers.
- 5. / a variability or spread in a variable or a probability distribution. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range.
- 8. / the difference between the greatest number and the least number in a set of numbers.
- 9. / the sum of a set of numbers divided by the number of elements in the set. (A type of average)

- 1. / a bar graph in which the labels for the bars are numerical intervals.
- 2. / In statistics, the absolute deviation of an element of a data set is the absolute difference between that element and a given point.
- 3. / a measure of how much a collection of data is spread out. Commonly used types include range and quartiles. (Also known as spread or dispersion).
- 4. / an average; a single value that is used to represent a collection of data. Three commonly used types of averages are mode, median, and mean. (Also called measures of central tendency)
- 5. / the science of collecting, organizing, representing, and interpreting data.
