Mean of class interval

WebApr 3, 2024 · We can see that the lower boundary of the previous class interval is equal to the upper boundary of the next class interval, which makes the given distribution table continuous. Let us first find the mean of the given frequency distribution. WebJun 21, 2024 · Exclusive series is the most common one, where we have class intervals like; 0-10, 10-20, etc. Inclusive series is the one where the class intervals are like; 0-9, 10-19, 20-29, etc. We can find the arithmetic mean using inclusive series directly, but sometimes it is asked to convert it into exclusive series and then find the arithmetic mean.
