relative frequency

• the frequency of a specific data value divided by the total number of data values in the set

• the ratio of a joint relative frequency to a related marginal relative frequency in a two-way table

• the ratio of the frequency in a particular category divided by the total number of data values

• the sum of the joint relative frequencies in a row or column of a two-way table

frequency

• the number of times the value appears in the data set

• a table that displays two-variable data by organizing it into rows and columns

• a two-way table that displays relative frequencies

• the frequency of a specific data value divided by the total number of data values in the set
