Math 231 1-3 Data Collection and Experimental Design Baldwin Ex 4: You are doing a study to determine the opinion of students at your school regarding stem cell research. Identify the sampling technique used. 1. You divide the student population with respect to majors and randomly select and question some students in each major. Students Selected are it so , is strata into divided stratified a and (majors) a sample is sample 2. You assign each student a number and generate random numbers. You then question each student whose number is randomly selected. Each equal has Selected so , size same has an being selected ↓ each equal chance of being of chance Student the of sample an this is simple a random Sample . 3. You select students who are in your biology class. The sample is taken available students . sample biology with This students so sample students stem , cell and from it may readily convenience is be biased as may be more familiar research than other may have stronger . opinions 6
