Question

Khanyisile Khumalo · Accepted Answer

Final Answer : B, Explanation :  A representative sample is one that is selected to match the population on important characteristics such as age and sex, in order to minimize bias and increase the generalizability of the findings. Volunteer bias refers to a type of bias that occurs when individuals who choose to participate in a study are different from those who choose not to participate, and can limit the generalizability of the findings. Experimental and control groups refer to specific groups in an experimental study, but do not necessarily reflect how the sample was selected.
