Guidelines for Plotting Frequency Distributions
The frequency distribution of events is the number of times each event occurred in an experiment or study.
Outliers
In statistics, an outlier is an observation that is numerically distant from the rest of the data.
Relative Frequency Distributions
A relative frequency is the fraction or proportion of times a value occurs in a data set.
Cumulative Frequency Distributions
A cumulative frequency distribution displays a running total of all the preceding frequencies in a frequency distribution.
