used when the range is large and classes several units in width are needed ungrouped frequency distribution used for numerical data and when range of data is small; each class is only one unit
The relative frequency histogram gives the fraction of times the data occur in the particular group or interval. Relative frequency distribution of a class is the ratio of the frequency of the class to the total number of the items.A uniform distribution often means that the number of classes is too small, each class has about the same number of elements. It may describe a distribution which has several peaks.he relative frequency table is a compact numerical way to present how the data is distributed. If the frequencies are plotted as columns, the resulting plot is called a histogram. A frequency distribution shows the number of items in each of several overlapping classes.
