Question

Quizplus · Accepted Answer

The concentration of disinfectant is the experimental variable, as it is the variable being manipulated in the experiment to determine its effect on the bacteria. The control would be a group that does not receive any disinfectant. The response variable would be the measure of bacterial growth or survival after exposure to various concentrations of disinfectant. The data collected would be the numerical values or measurements of bacterial growth/survival in each group. The hypothesis would be the proposed explanation or prediction for the results of the experiment.
