On your IGCSE GCSE Maths exam you will probably get a question about Histograms and Frequency Density. The total area of the histogram is equal to the number of data. To calculate frequency density we use the formula.
The frequency density goes up the y-axis and the area of each bar will represent the frequency.
This allows for a meaningful comparison of different classes where the class widths may not be equal. Introduction Frequency density is a way of presenting the frequency in a compacted way. Examples of Histogram Formula with Excel Template. If frequency is 90 to 100 for the plant species of interest reduce the quadrat size.
