Relative Frequency Histogram Example

A relative frequency histogram divides every bin count by the number of valid observations, so the bar heights represent shares of the sample rather than raw counts. Vizvero formats the Y axis and value labels as percentages while preserving the underlying observations.

How to structure the data

  • 01Enter the same raw numeric observations you would use for a frequency histogram.
  • 02Choose Relative frequency; Vizvero calculates every bin percentage from the valid observation count.
  • 03Keep bin boundaries consistent when comparing two separately created histograms so percentage differences remain interpretable.

What this example shows

Express each bin as a percentage of all observations instead of an absolute count.

Frequency vs relative frequency

Frequency is the number of observations in a bin. Relative frequency is that count divided by the total number of valid observations, usually shown as a proportion or percentage.
