Question 2
In a meta-analysis, the ES for the experimental versus control groups
was 0.68, which represents a percentile equivalent of 75. This means
that
the control group's average performance was 68 out of 100 compared
with 75 out of 100 for the experimental group
the average score of the experimental group was better than 75% of
the control group's scores
the probability is 75% that the use of the experimental treatment will
improve the average student's score from the 50th to the 68th
percentile
the control group's mean was only 75% as high as that of the
experimental group

Question 5
The fact that a meta-analysis quanties ndings from many studies is
a frequently mentioned advantage. Another strong advantage of the
meta-analysis over the normal review paper is
the use of the computer in the literature search

for excluding studies
the inclusion of theses and dissertations as well as journals

measurements

Quiz: Meta-Analysis and Survey Research: EXSC525: Research Methods in Exercise Science (B02)
The practice of selecting a small random sample of a survey's
nonrespondents is primarily intended to
try to raise the percentage of returns to at least 50%
identify outliers
determine whether the nonrespondents are a different population
from the respondents
ensure anonymity of responses

Question 19
A major difference in the purpose of a meta-analysis and a review of
literature for a research paper is that the meta-analysis uses the
literature
for empirical and theoretical conclusions
to document a need for a particular study
to determine what methods to use to conduct the meta-analysis
to formulate the research hypothesis for the meta-analysis

Question 21
Your Answer:
Contrast the electronic questionnaire with the personal interview in
terms of advantages or disadvantages in sampling, validity of
responses, and administrative considerations (time, expense, helpers)
(10pts).
In the electronic questionnaire it may be less exible during the data
collection process because the questions may not be changed. Conversely
the personal interviews will be more exible because of the type of data and
information provided by the data collectors methods used to acquire them.
The electronic questionnaire enables the collection of information from many
people at a time while personal interviews allow the collection of data from a
small number of persons. Personal interviews require a lot less amount of
resources to collect data while electronic questionnaire is more expensive
because of technology used. The time required to complete the process of
data collection depends on the participants as they respond to the electronic
questionnaire while the validity of response in the personal interviews
depends on the interviewer who controls the process.

Question 22
Your Answer:
In a paragraph or two, explain the purpose and procedures of a meta-
analysis to someone who has never heard of the research technique
(10pts).
The procedure of meta-analysis research is to follow a systematic research
process. The researcher applies systematic and reproducible methods in
9/24/23, 4:59 PM
Quiz: Meta-Analysis and Survey Research: EXSC525: Research Methods in Exercise Science (B02)
identifying, selecting, and critical appraisal of relevant studies. The researcher
integrates the results from the relevant studies creating a more precise
estimate for the outcomes. The purpose of meta-analysis research is that it
summarizes the many medical researches. According to Field and Gillet
(2010), meta-analysis creates statistical signicance on articles with
conicting ndings. This allows the researcher to attain a correct estimate.
Another purpose of meta-analysis is to increase information accessibility due
to the vast medical researches. The method introduces a precise estimate of
the average or overall effect. Lastly, the research method addresses research
problems that require the use of a large sample size. It also synthesizes
secondary sources through systematic analysis of articles. Unlike individual
studies, meta-analysis increases the ability to generalize a larger population
and statistical power. Besides, it is evidence-based research. However, the
drawback of the method it is time-consuming.
