Data where the values are categories.

• categorical data

• statistical data

• numerical data

• non-statistical data

A question which can be answered by a specific measurement or procedure where no variability is anticipated. For example, "How high is that building?" or "What period is this?"

• non-statistical question

• statistical question

• numerical data

• distribution

• shape

• data

• bell-shaped

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.
