SOCI 301 SOCIAL STATISTICS- FINAL EXAM
PRACTICE-with 100% verified solutions-2023-2024


1. If an exercise psychologist hypothesizes that there will be no difference between a
new conditioning program and the current conditioning used by a team, the
psychologist is stating the
a) comparison hypothesis.
b) research hypothesis.
c) null hypothesis.
d) functional differential.

2. Place the five steps of the hypothesis-testing process in the correct order.
1. Determine the characteristics of the comparison distribution.
2. Decide whether to reject the null hypothesis.
3. Restate the question as a research hypothesis and a null hypothesis about the
populations.
4. Determine your sample’s score on the comparison distribution.
5. Determine the cutoff sample score on the comparison distribution at which
the null hypothesis should be rejected.
a) 2, 4, 1, 5, 3
b) 3, 4, 1, 5, 2
c) 1, 3, 5, 4, 2
d) 3, 1, 5, 4, 2
e)
1. Which of the following statements is the MOST accurate description of
hypothesis testing??
a) It is a central theme in the statistical analysis of virtually all social
science research.
b) It is a simple part of statistics that applies to approximately three statistical
procedures.
c) It is a fairly uncommon way of using statistics.
d) It is a kind of statistical procedure that is used mainly as part of descriptive
statistics.
a.
1. A researcher tests whether there is any difference between how fast people work
in the morning versus how fast they work in the evening. What is the NULL
hypothesis?
a) People who work in the morning work faster.
b) People who work at night work faster.
c) There is some difference, but which is faster is not predicted.
d) There is no difference in the speed at which people work.
e) The difference between how fast people work in the morning and
how fast they work at night.

, 1. You determine the characteristics of the comparison distribution to answer which
of the following questions?
a) Given a particular sample value, what is the probability of
obtaining that value if the research hypothesis is true?
b) Given a particular sample value, what is the probability of
obtaining that value if the null hypothesis is true?
c) Given a particular population value, what is the probability of
obtaining that value if the research hypothesis is true?
d) Given a particular population value, what is the probability of
obtaining that value if the null hypothesis is false?
e) Given a particular population value, what is the probability of
obtaining that value if the research hypothesis is false?

1. The first step in the hypothesis-testing process is to:
a) Determine the characteristics of the comparison distribution
b) Decide whether to reject the null hypothesis
c) Restate the question as a research hypothesis and a null
hypothesis about populations
d) Determine your sample’s score on the comparison distribution
e) Determine the cutoff sample on the comparison distribution at
which the null hypothesis should be rejected.

1. The cutoff sample score is also known as the:
a) significance level
b) sampling distribution.
c) null value.
d) sample Z score.
e) critical value


1. Suppose the cutoff Z score on the comparison distribution is +2.31. You reject the
null hypothesis if the sample value’s Z score on this distribution was:
a) -2.16
b) -1.41
c) 2.16
d) 2.83
e) 2.30


1. A one-tailed test is associated with
a) the research hypothesis.
b) the null hypothesis.
