Description
1) Specify two hypotheses in which one variable is the independent variable in one hypothesis and the dependent variable in the other. Don't just reverse the variables (making the dependent variable the independent variable and vice versa). ONE variable should be the independent variable in one hypothesis and the dependent variable in the other hypothesis. Operationally define the independent variable and dependent variable in both hypotheses. Try to hypothesize one positive relationship and one negative relationship.
2) Explain the difference between mediating and moderating variables. Come up with yet another hypothesis that includes: independent variable, dependent variable, mediating variable, and moderating variable.
3) Explain what a spurious causal relationship is and come up with an example. Explain what the extraneous variable is that made the relationship between the independent variable and the dependent variable spurious. Finally, explain the difference between an extraneous variable and a control variable.

Question 1
Dependent and independent variables are the two main variables in a research
experiment. A dependent variable is a variable that is being measured or tested in a trial.
Independent variable, on the other hand, is a variable being controlled or changed to check its
effects on the dependent variable (Losh, 2017). My two interrelated hypotheses are:
a. Eating more vegetables helps someone lose weight faster,
b. Losing weight too fast leads to health issues including muscle cramps, dizziness,
reduced metabolism, and fatigue, among others.
In the first hypothesis, vegetables are the independent variables, and losing weight is the
depen...
