A list of all registered UCF students could serve as a _____________ if
we were interested in taking a sample of our population, defined as UCF
students. - ANSWERS-Sampling Frame
We need that list of all registered students if we want to do a Probability,
or random, sample. - ANSWERS-True
Larger samples are preferable to representative samples - ANSWERS-
False
_____________ refers to the differences between what you collect from
your sample and what actually exists in your population - ANSWERS-
Sampling Error
Non-Probability samples have error, whereas Probability, or Random

What goes into calculating the sample size needed for a study? -
ANSWERS-Confidence level, confidence interval, population, types of
questions/analyses.
Sampling Application - ANSWERS-Population: 2500 NSC majors
Preliminary Confidence Level: 95% Preliminary Confidence Interval:
3% Question: Favorable/Unfavorable Attitude toward moving to
downtown campus
What type of sample is this set up as? - ANSWERS-Probability, or
random sample
Researchers get a list of the 2500 NSC majors at UCF. What is this? -
ANSWERS-Sampling Frame
Given these parameters, the necessary sample size indicated is too great
to get responses from on a practical level. What can be done about this,
in terms of
A. The Confidence Level? B. The Confidence Interval? C. The sample
of students being used? - ANSWERS-A. Lower it (maybe 90%?) B.
Raise it (maybe up to 5%), C. Nothing - you can't get people who aren't
representative of your population
