Question

Felisha wants to determine if the amount of time stretching allows gymnast to do a back flips
correctly. She has 5 students stretch for zero minutes, another 5 students stretch for 5 minutes
and the other 5 students the normal stretching time of 15 minutes. Can you determine the
independent variable, dependent variable, control, and 2 constants in this experiment?

Answer 1

Answer:

An independent variable can be described as a variable which is changed in a scientific experiment to determine its effect on the dependent variable. In the following experiment amount of the time stretching is the independent variable.

A dependent variable can be described as the variable which depends on other factors. In the following experiment, back flips are the dependent variable.

A control experiment is the experiment which is used to compare the experimental groups. In the following experiment, five students which stretch for zero minutes is the control group.

A constant is the part that doesn't change in the experiment. In the following experiment the number of students  and the type of exercise or gymnast remains constant.
