In this situation, Lisa would need to at least test two of her family members. Where one group would grow their hair naturally, this would be labeled or referred to as "Control Group."
On the other hand, the second group would use Rogooti, this group would be labeled or referred to as "Independent variable."
Finally, she would need to estimate the length of hair grown over a given period of time which will be termed as "Dependent variable".
Answer: the control group is one of her family members who will grow there hair out naturally
The independent variable is the other family member who uses Rogooti then the dependent variable is she needs to estimate the length grown over a given period of time
