Split in three groups to see who can answer the same number of problems the fastest. One group gets no answers and no calculator. The next group gets can use a calculator. The third group was given the answers. Each group had the same amount of problems and a quiet room to work in.What is the independent, dependent, and controlled variable in this situation. ?
Group with answers = Controlled
*because it is what you would compare other results too.
Group with calc. = independent
and group with no answers or no calc = Dependent, because their results are constant
What is the independent, dependent, and controlled variable in this situation. ?
Independent variables are variables that can be controlled, but if another variable changes, this one doesn't change. In this case, it would be the number of problems and a quiet room.
Dependent variables are those that change when you alter another variable. For example, if you take away the answers, their speed to solve the problems will slow down. That is a dependent variable.
Controlled variables are those that you're using to experiment on the kids that can be changed by the person running the experiments. In this case, it would be the answers and the calculators.
depedent variable= thing that changes based on independent
number of problems answered the fastest
independent variable= calculator given to one group vs no calculator
control=the group that was given the answers
Independent-People in each group
Dependent-Intellegence of each student
Controlled-Whether or not they have a calculator
