b) No, you do not have any variables to test
c) No, there needs to be a control group that does not receive any shampoo
d) Yes, the variable being tested is the shampoo type and you are seeing how effective those shampoos are

In an experiment, the group that does not receive the variable is known as the
a) test group
b) responding variable
c) manipulated variable
d) control group

What is the correct order for the scientific method ?
a) Question, Data, Analysis, Conclusion
b) Question, Hypothesis, Procedure, Data, Analysis , Conclusion
c) Purpose, Hypothesis, Observations, Data, Conclusion
