This means that over the long term of doing an experiment over and over, you would expect this average. This “long-term average” is known as the mean or expected value of the experiment and is denoted by the Greek letter μμ . In other words, after conducting many trials of an experiment, you would expect this average value.

There are three types of distributions. A right (or positive) skewed distribution, a left (or negative) skewed distribution and a symmetrical distribution.

There is different work to be done to calculate each of them, and they have different uses, strengths, and weaknesses.

There are three measures of the “center” of the data. They are the mode, median, and mean. Any of the values can be referred to as the “average.”
