Consider the following experiments, identify the independent variable (IV), dependent variable (DV), and constant variable. Please answer parts 1,2,3,4 and 5 given. 1. David wanted to see if eating chocolates would help him do better on his classwork. The first day, he didn’t eat any chocolate. On day 2, he ate one bar of chocolate; on day 3, he ate 2 bars of chocolate; and on day 4, he ate 3 bars of chocolate. Each day, she recorded the grades she got on his science work. Independent Variable (IV): _____________________________________ Dependent Variable (DV): _____________________________________ Constant Variable (CV): _______________________________________ 2. Charles wanted to see if listening to music would make the basketball players make more baskets. On day one, he didn’t play any music and counted how many baskets they could make in 10 minutes. On day 2, he played rap music and counted the baskets, and on day 3, he played classical music and counted the baskets. Independent Variable (IV): _____________________________________ Dependent Variable (DV): _____________________________________ Constant Variable (CV): _______________________________________ 3. Michael wanted to see what kitchen cleaner could work best for cleaning his counter.He used Lysol, Clorox, Pinesol, and just water. For each cleaner, he put 5 milliliters of calamansi extract on the counter, sprayed the cleaner, and wiped it with one paper towel. Independent Variable (IV): _____________________________________ Dependent Variable (DV): _____________________________________ Constant Variable (CV): _______________________________________
