Discuss the difference between parametric and nonparametric statistics

Discuss the difference between parametric and nonparametric statistics.

Description

Discuss the difference between parametric and nonparametric statistics and make sure to cover all of the following points: 1) When are each appropriate to use and under what circumstances? 2) Provide a real-world example where each is appropriate to use. What would the outcomes of these statistical tests administered within your real-world context be (in other words: what would you expect to find when using your recommended statistical test in your real-world example situations)?
