Equal averages

That's fine. The mode is simply the number that occurs most frequently in a data set that contains repeated numbers. Thus, our answer is 77.

Here are my initial results followed by my thoughts. I wanted to express what I found as an single elegant formula but couldn't manage it, so here is a description instead.

Mean, Median, and Mode

I haven't produced a method for calculation at 7 variables yet. First, we add them, and get 88. I dislike the idea that the range is an average; it is surely a measure of dispersion, not of central tendency. Mark favorite. For example, most teachers give their students percentage grades, ranging from 0 to 100.

Solving Math Problems : How to Find the Median of a Series of Numbers

Then, you would divide that number by 4, because you are averaging 4 numbers together. With this in mind let's continue to the second example:. The tally chart below shows the results of a survey in which students identified the type of apple they like to have for a snack.
