What is a response variable in statistics?
This can refer to different things. A response variable is a variable in a statistical model that corresponds to the outcome of an experiment that you’re trying to measure.
This is typically when you test something like drugs or workouts and the statistic determines whether they help, whether they are safe, how they affect the body, etc.
Many estimates of requirements for foods and minerals come from this type of experimentation, analysis of what happens when a certain lab animal (such as a mouse) is fed with certain amounts of various substances (such as protein) for so many days on average (say 100). Some responses are average weight gained in grams per day while other responses can be more complicated measurements such as number of tumors on each side where one group is given substances A and B versus another group that receives substance B alone.
