Example. The correlation between proba-bility of producing the same meaning across four associ­ ations and primary meaning strength was .84. A relative frequency table is a table that records counts of data in percentage form, aka relative frequency. To compute relative frequency, one obtains a frequency count for the total population and a frequency count for a subgroup of the population. A straightforward calculation determines the relative frequency from the frequency by adding up all the classes' frequencies and dividing the count by each class by the sum of these frequencies. Thus, a relative frequency of 0.50 The ratio of the number of times an event occurs in a series of trials of a chance experiment to the number of trials of the experiment performed.

Evidence suggests that the processing of homonyms, or words with multiple unrelated meanings (e.g., “money/river bank”), varies depending on the relative frequencies of their meanings [e.g., 1, 2, 3, 4].Here, we provide the first meaning-frequency ratings in British English that were collected online using the eDom norming procedure []. b. the proportion of the range of a random variable taking a given value or lying in a given interval. The statistical process has absolute frequencies and relative frequencies. Imagine sampling 10 numbers and computing the mean over and over again, say about 1,000 times, and then constructing a relative frequency distribution of those 1,000 means.
