Suppose the school board wished to see whether the age of the student affecis test achievement. The Lesting coordinator separated the raster of high school students into freshmen, sophomores, juniors, and seniors and randomly selected 20 students from each classification. She then flipped a coin to determine which test format each student would receive and then compared the results as follows: • Freshmen who took the multiple choice test compared to freshmen who took the fill-in-the blank exam • Multiple chaice sophomares compared to fill-in-the blank sophomares • Multiple chaice juniors compared to fill-in-the blank juniars • Multiple chaice seniors compared to fill-in-the blank seniors.

Question 2
Suppose the school board wished to see whether the age of the student affecis test achievement. The Lesting caordinator separated the raster of high school
Students into freshmen, sophomores, juniors, and seniors and randomly selected 20 students from each classification. She then flipped a coin to determine which
test format each student would receive and then compared the results as follows:
• Freshmen who took the multiple-choice test compared to freshmen who took the fill-in-the blank exam
• Muliple chaice saphomares compared to fill-in-the-blank saphomares
• Muliple-chaice juniors compared ta fill-in-the blank juniors
• Muliple chaice seniors compared to fill-in-the-blank seniors.
Randomization still occurred because the testing coordinator flipped the coin to assign the test format to each student. This approach is an example of what type
of sampling technique?
Your answer:
O Simple random sampling
O Stratified random sampling
O Systematic sampling
O Cluster sampling
o Convenience sampling
