Question

A nurse practitioner (NP) in a primary care clinic decides to study the health promotion practices of her patients. The NP makes a list of all adult patients seen in the clinic for the past 6 months. There are 475 patients on the list. By assigning a number to each name and using a table of random numbers, the NP selects 100 patients to be invited to participate in the study. What type of sample has been selected? Convenience Sample Stratified Random Sample Simple Random Sample Purposive Sample

Answer 1

it is not convenience sampling because the nurse practitioner has not used any medium for sampling which was convenient for her. So, option A is incorrct

option B is incorrect because we know that the nurse practitioner has not divided the population sub parts and for stratified sampling, there must be sub grouping for population.

option C is incorrect because using a random number table provides equal chances for each one of the 475 patients. So, option C is answer

option D is incorrect because it is not based on non probabilistic samping method and with the use of random number table, probability of selecting an individual patient is equal for all patients.

answer is option C (simple random sampling)
