A table that lists all of the classes and the number of data values that belong to each of the classes. A distribution in which most of the data values are located to the right of the mean is called a left-skewed distribution, while a distribution in which most of the data values are located to the left of the mean is called a right-skewed distribution.
A bar graph is a plot made of bars whose heights (vertical bars) or lengths (horizontal bars) represent the frequencies of each category, with space between each bar.
The vertical axis of a histogram is labelled frequency density.
A frequency table is a table that summarizes a data set by stating the number of times each value occurs within the data set.
A histogram is a display that indicates the frequency of specified ranges of continuous data values on a graph in the form of immediately adjacent bars.
An interval is a range of data in a data set.
The range of a data set is the difference between the smallest value and the greatest value in the data set.
A right-skewed distribution has a peak to the left of the distribution and data values that taper off to the right.
If a data set has only 1 value that occurs most often, the set is called unimodal.
