Document Summary

These are the parts that we will be talking about. In here the group of interest is children. This question is not specific to ethic, age groups etc. Instead it is referring to all the children in the world. If you are making a study from a small group to a large then you are not able to prove this as right. I am looking at the relationship between the variables: leptokurtic curve is where everything is kinds shifted to the middle. If you have a higher sample size, then this can actually pull the mean down. Inferential statistics: the more people you have the less sampling errors you have and less variability. When you are looking at mean difference you may have some differences in both end. If there is no difference, then you would refer to this as a null hypothesis.
