d. a subset of individuals drawn from the entire group of individuals relevant to your research.
What differentiates a representative sample from a non-representative sample? a. Representative samples are always larger.
b. Representative samples shares the essential characteristics of the population from which it was drawn whereas non-representative samples do not.
c. Non-representative samples are drawn from broader populations compared to representative populations and produce

large.

Which of the following is not a reason why labeling populations require some thought and consideration? a. Some journal editors may request particular labels when you submit work for publications.
b. You may end up using a label that is not
appropriate or even disrespectful for certain populations.
c. Once you choose a label, all future researchers must adhere to that same label because labels do not change.
d. You may end up revealing confidential information about the participants.
Which of the following best defines random sampling? a. Researchers stationing themselves at a particular location with access to parts
of the population and randomly selecting those who pass by.
b. Each member having the same opportunity and probability as other members of the population to be selected for participation in a study.
c. Each member having a random probability of being selected. Not all members of the population have the same probability of being selected.
d. Researchers have more than one population of interest and sample
randomly across these different populations not knowing which population they are sampling from. This helps reduce bias.
What is the main benefit of using random sampling? a. It is the most straightforward way to obtain a representative sample.
b. It is the most straightforward way to obtain a statistically powerful sample.

from which the results of the study will be applicable to other populations.

What is the biggest barrier to using random sampling? a. It is often unethical. You should not have all participants have equal chances of being selected because some might not want to participate.
b. It is only usable when
the population is large. Thus, it is not useful for most research.
c. It is often impractical as researchers usually do not have access to the entire population of interest to recruit them randomly.
d. It is biased because the randomness makes it difficult to analyze the data that you collect.
What do alternatives to random sampling accomplish? a. They make the sample less
biased.
b. They are ways to deal with lack of accessibility to some members of the population.
c. They are non-probability samples.
d. They are ways to deal with randomness in the data that random sampling produces.
What distinguishes stratified sampling from oversampling? a. Stratified sampling is when a researcher intentionally over-recruits
members of underrepresented groups whereas oversampling is a non-probability sample.
b. Stratified sampling does not aim for a generalizable sample while oversampling does.
c. Oversampling does not aim for a generalizable sample while stratified sampling does.
d. Stratified sampling divides the population into homogeneous groups along some dimension whereas oversampling is when a researcher intentionally
over-recruit underrepresented groups.
How or why does stratified sampling help with representativeness of your sample? a. Stratified sampling produces a non-probability sample.
b. Stratified sampling divides the population into homogeneous groups and you can ensure you sample enough along that dimension of interest.
c. Stratified sampling over-recruits samples in the most
inaccessible category.
d. Stratified sampling samples via participant networks. Participants help recruit and therefore you gain a representative sample.
When is non-probability sample appropriate to be used? a. When the population is too diverse.
b. When representativeness of your sample is not important to your research.
c. When you hope to use
oversampling techniques.
d. When you only need a relatively small sample.
The use of college undergraduates from introductory psychology courses in psychological research is an example of a… a. random sample.
b. stratified sample.
c. convenience sample.
d. snowball sample.
Which of the
following is not an advantage of using an online sample? a. Collecting data is usually fast.
b. Collecting data is often cheap.
c. Collecting data is often in direct contact (i.e., in person) with the participant in a laboratory setting.
d. There is often a large pool of participant pool from which you may sample.
With regards to representing the
larger population, which of the following is true? a. Researchers initially had doubts about the representativeness of samples recruited from Mturk, but recent evidence provided by Buhrmester, Kwang, and Gosling (2011) suggest that Mturk samples surpass other internet samples and many U.S. college samples.
b. Researchers have had doubts about the representativeness of samples recruited from Mturk, and recent evidence provided by Buhrmester,
Kwang, and Gosling (2011) supports the validity of that concern.
c. Researchers initially had very little, if any, doubts about the representativeness of samples recruited from Mturk, but recent evidence provided by Buhrmester, Kwang, but Gosling (2011) suggest that Mturk are not representative of the population at large.
d. Researchers initially had very little, if any, doubts about the representativeness of samples recruited from
Mturk, but recent evidence provided by Buhrmester, Kwang, and Gosling (2011) suggest that Mturk samples surpass other internet samples and many U.S. college samples.

b. Parametric tests make fewer assumptions than non-parametric scales, and can only be used on interval and ratio tests.
c. Non-parametric tests are preferred over parametric tests, particularly because they can be applied to a wider range of measurement scales.
d.
Parametric and non-parametric tests can be used on the same types of measurement scales. Which you use depends entirely on your research question.

Which of the following reasons below is not one that describes the importance of formulating an
analysis plan before you collect data? a. It helps you limit potential false positives to a minimum.
b. It limits the potential accusations of p-hacking in your research.

d. It helps you think through whether the measures you used are logical.
What is the difference between target and accessible population?
The interest of the researcher in selecting members of the target population is to reach candidates who can describe their experiences to address the research goal. The accessible population is composed of members of the target population who are willing to participate and will be available at the time of the study.
What is the difference between target population and sample population?
The target population of a survey is the population you wish to study. The sampled population is the population which you are able to observe in a sample.
What is the difference between target population?
The difference between Target population and Survey population can be summarised as follows: A Target population is the population outlined in the survey objectives about which information is to be sought. A Survey population is the population from which information can be obtained in the survey.
What do you mean by accessible population?
Accessible population. the portion of the population to which the researcher has reasonable access; may be a subset of the target population. May be limited to region, state, city, county, or institution. Examples.
