You are designing an experiment in which you play different types of music to see if it helps with memory. You have decided to try three different types of music (Hard rock, Classical, Pop), as well as no music at all. Subjects will read a story, and be given a short quiz afterwards, which will be scored by counting the number of questions correct. What type of data is the dependent variable?

Consider an experiment where we're trying to determine how much water is needed to grow tomatoes. We have 16 pots with one tomato plant in each. We decide to try four different amounts of water (2 oz., 4, 6, 8). Our garden borders an ally, which may affect yield, so we tracked which row the plant was in as well.At the end of the study, the yield of tomatoes will be measured. Given no other information, what type of design is this?
