Social Studies

Molodets [167]2 years ago

The confidence interval methods for the mean are resilient against deviations from normality, which means they can be used with non-normal distributions as long as the deviations are moderate.

<h3>Explain Non-normal distribution?</h3>

Non-normal Data is clumped up on one side or the other of distributions, with decreasing amounts trailing-off to the left or right.

You have a variety of alternatives for dealing with your non normal data. The assumption of normality is made by several tests, including the one sample Z test, T test, and ANOVA. If your sample size is large enough, you might still be able to perform these experiments (usually over 20 items). You can also decide to apply a function to the data to alter it and make it fit a standard model. However, you might wish to perform a non parametric test if your sample is very tiny, skewed, or naturally fits another type of distribution.
