A statistical question must have variable answers because it seeks to understand the variability or differences within a population or sample. The question should not have a single, fixed answer, but instead should allow for a range of possible responses. By examining the variation in the data, statisticians can draw conclusions and make inferences about the population being studied.
For example, a statistical question could be "What is the average height of students in a particular school?" In this case, the answers (heights) can vary from student to student, making it a statistical question.
