WebThe frequency density formula is a calculation that involves dividing the frequency by the class width. We use frequency density to plot histograms which show frequency distribution. The larger the area of the bar on a histogram, the higher the frequency. We can calculate the frequency density by using the formula WebHere's a quick preview of the steps we're about to follow: Step 1: Find the mean. Step 2: For each data point, find the square of its distance to the mean. Step 3: Sum the values from Step 2. Step 4: Divide by the number of data points. Step 5: …
