Question

A researcher wants to determine the average height of students in a university using convenience sampling. They measure the height of 15 students selected based on their availability and accessibility. The mean height of these students is 170 cm with a standard deviation of 5 cm. Can the researcher use this sample to make inferences about the population of all students at the university?

Expert Solution

Step 1

No, the researcher cannot use this sample to make inferences about the population of all students at the university. The sample was selected using convenience sampling, which is a non-probability sampling method and may not be representative of the population. The sample size is also small, making it difficult to generalize the results to the larger population of students at the university. To make inferences about the population, a more rigorous and representative sampling method such as simple random sampling should be used.
