a) What would be 3 main variables of interest that you think would help to predict level of enjoyment? Explain your reasoning.
b) What would the relationship that you would expect between each variable you chose and level of enjoyment (i.e. would they be positive or negative)? Explain briefly why you posit this relationship for each variable with level of enjoyment.
