Unit 1
2 pages

Any one
Correlational,
descriptive and historical research are classified under one category known as
nonexperimental
research. Explain how these types of research are the same and how they are
different.
2. Discuss the
characteristics of a good research hypothesis. What distinguishes a null
hypothesis
from a research
hypothesis? How would you explain the difference between nondirectional
research and
directional research hypotheses?
3. Discuss the
different types of sources (i.e. general, primary, and secondary). What are the

differences among
these sources? Why is it important that researchers utilize primary sources
when conducting a thorough review of the
literature?

1. Summarize the
four levels of measurement first proposed by Stevens in 1951. Explain how
knowing the level of
measurement for variables helps a researcher examine outcomes in a study.
Diagram the
relationship of precision and levels of measurement.
2. Propose the
reason that tests are so popular in the field of assessment and social
research.
Consider the type of
information they provide and how they could be misused.
3. Outline the fours
steps in the data collection process. Explain why it is so important to be
systematic in collecting data.

Unit 3
Any one
Explain how the
results of a study can be statistically significant but not meaningful. Propose
an
example of when this
might occur.
2. Illustrate what a
visual inspection of your data through the use of a scatter plot can help you
determine. Summarize
the relationship between data points on a scatter plot and a correlation
coefficient.
3. Distinguish
qualitative research methods from those categorized as quantitative methods.
Outline what types
of questions qualitative research addresses that cannot be addressed by
quantitative research.

Unit 4
Any one
Explain how the
presence of a control group accounts for threats to internal validity.
Summarize
the types of threats
to internal validity that can be avoided by utilizing random assignment to
control and
experimental groups.
2. Consider the
tasks that every researcher should address when preparing for data collection
and
analyses. Illustrate
their importance.
3. Outline the basic
“rule of thumb” that researchers follow when formatting a manuscript for
publication.
