WebApr 6, 2024 · In this first step, calculate the difference between the upper class limit of one class interval and the lower limit of the next class interval. The next step is to divide the difference by two, and then add the resulting value to the upper limit of every class interval and subtract it from the lower limit of every class interval. Example: WebFeb 6, 2024 · The class width is the difference between class boundaries (may or may not be the same as class limits). For example, 10 − 19 3 20 … WebTherefore the modal class intervals are 50 up to 55 and 55 up to 60. So as you can see working out the modal class interval is very quick and easy to do. However, working out the mean and median can be harder to work out (see below for help on finding the mean and median from a frequency table). Questions & Answers michael therriault actor
