It has been traditional for the man rather than the woman to receive the check when a couple dines out. a researcher wondered whether this would be true if the woman was clearly in charge, asking for the wine list, questioning the waiter about dishes on the menu, etc. a large random sample of restaurants was selected. one couple was used in all restaurants, but in half the man assumed the traditional in-charge role, and in the other half the woman was in charge. at each restaurant, the couple recorded whether the check was presented to the man or to the woman. the researcher hypothesized that the check will be presented to the person showing in-charge behavior. identify the independent and dependent variables

Check being presented to the gender is the dependent variable

Which gender takes charge is the independent variable

Explanation:

The relationship between two variables is found observing which variable changes the other.

When a variable changes irrespective of the other variable it is the independent variable.

When a variable changes with respect to the independent variable it is the dependent variable.

Here, the effect of who takes charge during dinner is being observed and whether this effect causes a change in who the check is presented to is noted.

Hence the check being presented to the gender is the dependent variable and which gender takes charge is the independent variable.

"choosing is refusing" means individuals face an opportunity cost with each decision they make. economists state that every decision involves trade-offs. opportunity cost is the least desirable alternative given up as a result of a decision.
