Megan wants to see if mice that are fed food a or b grow at a faster rate. she measures the mass of the mice on day 1, then divides them into two groups based on the type of food they will be given. she feeds each group the same amount of food at the same time each day. does megan have a control group in this experiment? no, there is no control group because she changes more than one variable. no, there is no control group because each group is treated under test conditions. yes, the mice that are fed food a are the control group, and those that are fed food b are the test group. yes, the mice that are fed food b are the control group, and those that are fed food a are the test group.
