Question

• What is more useful for computing and understanding a measure of something, the average or the standard deviation? Why?
• Why would you use a nonparametric statistic?
• If two things are correlated, does that mean one thing is causing the other to happen?

Answer 1

1) What is more useful for computing and understanding a measure of something, the average or the standard deviation? Why?

• Average and Standard Deviation are extent of center and spread independently. In any case ordinary is definitely not hard to figure and adequately understandable to a layman in addition

2) Why would you use a non parametric statistic?

• Frequently, everything considered, condition we find the use of parametric estimations is limited as they make a couple of necessity and assumptions about the allocation of the data, etc. On the other hand we find that non parametric estimation are fundamentally increasingly versatile in this situation. In like manner their application diminishes the complexcity parametric bits of knowledge incorporates. To the exclusion of everything else non parametric estimation is useful for ordinal data as well.

3) If two things are correlated, does that mean one thing is causing the other to happen?

• If two thing are related, that does not continually suggest that one is causing the other. For example the rising advancement of paddy in a field and the amount of understudies going in a test may show a positive association anyway they no spot have a causal relationship .
