Relative Frequency Distribution in Statistics

Relative frequency distribution in statistics is a graphical representation of the frequencies of occurrence of values in a data set. It is created by plotting the relative frequencies of the data values on a vertical axis and the corresponding data values on a horizontal axis. The height of each bar in the graph represents the relative frequency of the corresponding data value. This type of distribution is most commonly used to visualize the distribution of a small data set.

Relative frequency distribution in statistics can help identify outliers in a data set and determine the distribution’s shape. By comparing the height of the bars in the graph to one another, you can get a sense of which values are more common, and which values are less common. If the bars are all approximately the same height, the distribution is symmetrical. If the bars are not all approximately the same height, the distribution is skewed. You can also use a relative frequency distribution to compare two or more data sets.

Joint Relative Frequency Distribution

A joint relative frequency distribution is a graphical representation of the frequencies of occurrence of values in two or more data sets. It is created by plotting the joint relative frequencies of the data values on a vertical axis and the corresponding values on a horizontal axis. The height of each bar in the graph represents the joint relative frequency of the corresponding data value. This type of distribution is most commonly used to visualize the distribution of two or more data sets.

A joint relative frequency distribution can help identify outliers in two or more data sets and determine the distributions’ shape. By comparing the height of the bars in the graph to one another, you can see which values are more common and which values are less common. If the bars are all approximately the same height, the distributions are symmetrical. If the bars are not all approximately the same height, the distributions are skewed.
