How to find mean from a grouped frequency table. 3 marks Modal class. Hence the observation with the highest frequency will be the mode of the given data. To find the mode for ungrouped data it would be better to arrange the data values either in ascending or descending order so that we can easily find the repeated values and their frequency.

The limiting points of each class are called the lower class limit and the upper class limit and the class width is the distance between the lower or higher limits of successive classes. Grouped column plot with asterisk bracket to show significant differences. Here we must find the class which has the highest frequency this is the modal class.

Alternatively we can form a frequency distribution table to get the. Options for customization include flexible spacing between subgroups placement of asterisk brackets to highlight comparisons and patterns for each column. Tick labels can be shown as a second row table.

The frequency f of each class is just the number of data points it has. A frequency distribution is a table that includes intervals of data points called classes and the total number of entries in each class.
