Numerical Data Distribution

For a numerical or categorical data set, this tells you how many of each value or each category there are in the data set.

• distribution

• shape

• data

• bell-shaped

This consists of the minimum, the three quartiles, and the maximum. It is often indicated by a box plot.

• five-number summary

• statistical question

• data

• geogebra

A distribution whose dot plot or histogram takes the form of a bell with most of the data clustered near the center and fewer points farther from the center.

A distribution with two very common data values seen in a dot plot or histogram as distinct peaks.

A distribution where one side of the distribution has more values farther from the bulk of the data than the other side, so that the mean is not equal to the median.

A distribution with a vertical line of symmetry in the center of the graphical representation, so that the mean is equal to the median.

A distribution which has the data values evenly distributed throughout the range of the data.

A quantity that is calculated from sample data, such as the mean, median, or MAD (mean absolute deviation).

• statistic

• measure of variation

• standard deviation

• hand sanitizer

A measure of the variability, or spread, of a distribution calculated by a method similar to the method for calculating the MAD (mean absolute deviation).

• standard deviation

• MAD

• mean

• mode

A summary statistic that represents the amount of dispersion in a data set. It defines how far away the data points tend to fall from the center. Examples: IQR (interquartile range), MAD (mean absolute deviation), and standard deviation.

• measure of center
