In your study to determine the best method to teach current

events to freshmen college students at your college, what would constitute your population and sample, and how would your sample be chosen and why? After obtaining your results, if you find that the new method produced higher scores than the old method of instruction, how will you determine if this difference was a "real difference" or occurred by chance?
What will be an ideal response?

ANSWER: Answer will include that your population would be all the college students at your college, while the sample would be the students from the college that took part in your experiment. In order to make the sample representative of the entire student body at the college, your sample should be chosen randomly (random selection) to ensure that every member of the population has an equal chance of being in the sample. If a difference is found in favor of the new method, then tests of statistical significance would be used to determine how often these results could have occurred by chance alone. If your results could only have occurred by chance five times or less out of 100, then the difference between the two groups was significant, and you have data to support using the new method of instruction.
