Frequency chart
A frequency chart, or bar chart, displays the most and least frequent values of a column along with their number of occurrences. It shows how many times a value is present in the column.
A frequency chart is available only if Categorical Data = true.
If available, this chart is shown in the Frequency tab of the Descriptive Statistics.
Distribution chart
The data distribution chart, or histogram, displays how data is distributed.
A distribution chart is available only if the data type is Whole Number or Decimal Number.
If available, this chart is shown in the Distribution tab of the Descriptive Statistics.
In this chart, you can receive extra information such as the mean, standard deviation and so on, by clicking the Expand icon and selecting the options at the right of the chart.
