Be sure to explain how significance is determined in simple terms as well.

2. What is an interaction? Describe an example; what are the variables within your population (work, social, academic, etc.) for which you might expect interactions?

Define a statistical interaction and how it affects your results. Give an example. List the variables that are interacting and why.

3.What is an example in the world around you for which you would use a Chi-square analysis? Be specific. Describe what chi square tests and how your example is relevant. You may describe a Chi Square test, but you must also include a real-world example of a study that could use Chi Square. Do not copy and paste an example from the internet. Create your own.

4.Now that you are familiar with the basic concepts of statistics, what are some examples of when you have seen or heard statistics used inappropriately? Use the knowledge that you have obtained to be specific with this question.
