Experiment: three types of antibacterial soap, and a sample sized people, lets say 100 people wash their hands per soap. and c how many bacterias are left on their hands after washing. Please give me examples of the questions asked if you do not mind. thank u
Scientific Question, Independent variable, Dependent variable, control group, how to improve accuracy?|||The independent variable is type of soap because you can control that. The dependent variable is number of bacteria because that (possibly) changes due to the soap.
A control group would be people who washed their hands using no soap or possibly a non-anti-bacterial type.
