Question

Gueguen and Jacob asked waitresses to wear different colored T-shirts on different days for a six-week period and recorded the tips left by male customers. The results show that male customers significantly bigger tips to waitresses when they were wearing red. For this study, identify the independent variable and the dependent variable

Answer 1

Dependent Variable = tips left by male customers

Independent Variable = T-Shirt color worn by waitresses

Explanation:

Dependent variable is the variable that changes when the independent variable changes.

In other words, when the independent variable is varied, the dependent variable changes. The dependent variable is the effect or outcome of the manipulation of the independent variable.

In the study referred to in the question above, the amount of tips given to waitresses is dependent on the color of the T-shirt the waitresses wear.

Therefore, the dependent variable is T-Shirt color, while the independent variable is the amount of tips given.
