blood is thicker than water Start by operationally defining your proverb (what is the definition you give it), then identify your Predictor and Criterion variables (measured variables) and their definition for making a correlation. Assuming the correlation is high, we can then transform the correlation into an actual experiment (causal claim). For this we need to have an IV (with 2 levels), and a DV (measured/outcome variable) defined. For each type of research you will provide the information (what type of correlation, what type of effect) for your research. At the end of the 2nd part, please list 3 variables that may confound this experiment (like the examples in the tutorial)
