Testable Question: How well does each basketball player perform after drinking water, Gatorade, or Powerade?
Hypothesis: If a player drinks water to stay hydrated during a game, then that player will perform better than the players who drank Gatorade or Powerade because water is a natural resource and will keep the body hydrated best.
Control Group: players not drinking water, Gatorade or Powerade to stay hydrated.
Experimental Group: players drinking water, Gatorade, or Powerade to stay hydrated.
Independent Variable: water, Gatorade, and Powerade.
Dependent Variable: how well the players preform.
Constant: the amount of liquid each player consumes during the game (such as one-half liter every quarter).

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
