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)?
