Use the situation below for Part A, Part B, and Part C.

Question

A teacher is interested in determining the effect the amount of time spent studying has on mathematics test scores. The teacher surveys twenty students in her first-period class.

Part A: Identify the type of sampling being used.

Part B: Is the method of sampling used appropriate or inappropriate for drawing valid conclusions?

Part C: Explain your answer to Part B with a complete sentence.

Answer 1

A) Convenience Sampling

B) This method is innappropriate for drawing valid conclusions

C) Convenience sampling relies on choosing people who are easily accessible or readily available, which could introduce bias and result in an inaccurate representation of the entire population. It is inappropriate for reaching valid conclusions. The sample might not be representative of all students, and the findings might not be transferable to different populations or situations. As a result, the validity of the conclusions reached using this sampling technique may be constrained.
