MHA 705 UPDATED TEST EVALUATION QUESTIONS AND
SOLUTIONS RATED A+
✔✔What is a pilot study? - ✔✔A pilot study is a "trial run." It shows that it is logistically
feasible for the research study to be conducted on a
larger scale.
✔✔Why are survey researchers concerned about their response rates? -
✔✔Researchers are concerned about their response rates
because low response rates could breach both internal
and external validity of a study. A low response rate
could represent bias, introduce inaccuracy, or make generalization to the population
impossible.
✔✔What common mistake do researchers make in data collection? - ✔✔Two common
mistakes that researchers make in data
collection are lack of planning and deviation from the
original plan.
✔✔How do descriptive and inferential statistics differ? - ✔✔Descriptive (summary)
statistics describe the data
through techniques such as means, frequency distributions, and variations. Inferential
statistics allow the
researchers to make inferences about the population
characteristics (parameters) based on the characteristics
of the sample.
✔✔How many variables do bivariate statistical techniques involve? - ✔✔Bivariate
statistical techniques involve two variables.
✔✔What inferential statistical techniques emphasize differences in groups? - ✔✔Paired
t-test and analysis of variance (ANOVA) are
inferential statistical techniques that emphasize differences in groups.
✔✔What are two types of continuous data? - ✔✔Researchers must know the type of
data that they are
collecting because certain statistical techniques require
data of a particular kind.
✔✔Why must researchers know the type of data they are collecting? - ✔✔Researchers
might use Epi-Info because it is especially
designed for their type of study, epidemiological. It
makes conducting the research easier by calculating the
proper sample size and setting up the entry of data from
, questionnaires. In addition, Epi-Info is a dedicated statistical package. This means that
Epi-Info requires less
manipulation of the data and performs many statistical
procedures. Finally, the software is free from the Centers for Disease Control and
Prevention.
✔✔Why might a researcher use Epi-Info as his or her statistical package? - ✔✔The
research findings and discussion sections differ in
content and tone. The research findings section contains only the findings of the
analysis of the data. No
commentary about the findings is included. In the discussion section, researchers
interpret and explain their
findings and compare them to other researchers' findings. The researchers also
comment on the significance
of their study in terms of expanding the field's body of
knowledge or of adding to a theory. The discussion section is more creative than the
research findings section.
✔✔How do the research findings and discussion sections differ? - ✔✔First, they should
consider that they should present the
element in only one mode (narrative, table, or figure).
Second, they should consider which mode would be most
meaningful and understandable to the reader.
✔✔What two factors should researchers consider when determining how to present a
particular data element? - ✔✔A researcher should answer any three of the following
questions when writing the discussion section:
● What theoretical significance or practical worth do
the findings have?
● How do the findings link explicitly to the larger body
of knowledge?
● How have the findings improved the field's research
model?
● How have the findings expanded the body of
knowledge?
● What new definitions have the findings added to the
field's area of practice?
● How do the findings support practitioners in the
workplace?
● What problems do the findings solve?
● What valid conclusions can the researchers and the
readers draw from the findings?
● How can other researchers expand or improve this
research study?
