You decide to design an experiment to test whether the volume of water in a cup affects the rate at which alka-seltzer tablets dissolve. You set up 5 cups filled with different amounts of water, but all with the same temperature water. You then measure the amount of time it takes to dissolve one alka-seltzer tablet in each of the cups. In this experiment, water temperature is a variable. Are you collecting qualitative or quantitative data?
A) Qualitative
B) Quantitative
