Question

1. What is p-hacking? What is HARKing? Search these terms and read about them using more than one source. Why might these practices be questionable in terms of research ethics?

2. Come up with two unique examples of a study in which it would make sense to use each of the following type of analysis (one example for each): 1. Two Way ANOVA

Example:

2. Regression analysis

Answer 1

2) We are asked to give an example for each of the following type of analysis.

1) Two Way ANOVA: Two Way ANOVA is used when we want to estimate how the mean of a quantitative variable is affected by the levels of two categorical variables. It is also used when we want to how two independent variables in combination affect a dependent variable.

Example: Is there a difference in mean life of the batteries for differing material types and operating temperature levels at levels (1,2,3) for differing material types and low(-10 degrees celsius), medium(20 degrees celsius) and high(45 degrees celsius) for temperature levels.

In this case battery life is a continuous variable whose mean is affected by the two categorical variables(differing material types) and temperature levels.

2) Regression analysis: Regression analysis is used when we want to model or analyze data It is also used to describe the relationship between the independent variable and the dependent variable.

Example: You want to know if there is a relationship between food consumption and body mass.
