To find the class mark frequency, first determine the midpoint of each class interval by averaging the lower and upper boundaries. Then, tally the number of data points that fall within each class interval to establish the frequency. The class mark is typically used to represent the data points for that interval in further calculations, such as finding the mean. Finally, you can summarize the results in a frequency table for clarity.
To calculate the frequency density we will simply divide the frequency by the class width.
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
