Squaring the difference between the observed and the expected outcome does two things?
Homework Answers
Squaring the difference between the observed and the expected outcome does as making the significant of mean deviation otherwise sum of deviation is zero (0).
Step of squaring the deviations overcome the problem of signs in mean deviation.it is also suitable for further mathematical treatment. also it is affected least by fluctions of sampling.
Mean deviation = difference between the observed and the expected outcome.
Mean deviation = Xi - E(Xi)
