Find the distance of each value from that mean subtract the mean from each value ignore minus signs 3. An equals sign two or more variables x y etc example. 21 2 3.

Calculate the sample mean and the sample standard deviation s. Then find the mean of those distances. A rule or fact written with mathematical symbols.

The mean of a probability distribution is the long run arithmetic average value of a random variable having that distribution. In our routine life you can check the best route to your school you can check where more discounted products are available in the market and you can check which bank can offer the superior interests.
