Question 1

Which of the following is not one of the types of probability sampling procedures?
A)cluster
B)simple
C)convenient
D)stratified

Accepted Answer

Cluster, simple, and stratified sampling are all types of probability sampling, whereas convenient sampling is a type of non-probability sampling. Therefore, choice C is not one of the types of probability sampling procedures.

Question 2

Random sampling in which every k^th person is selected for participation in a study is called ________sampling. A)simple B)systematic C)stratified D)snowball

Accepted Answer

The described sampling method is systematic sampling, as it involves selecting every kth person from a population in a consistent and pre-determined manner. Simple random sampling involves randomly selecting individuals from a population without any predetermined pattern, stratified sampling involves dividing a population into subgroups and selecting individuals from each subgroup, and snowball sampling involves asking participants to refer others they know who may fit the study criteria. None of these methods match the description given in the question.

Question 3

Which of the following is not one of the types of probability sampling procedures?
A)simple
B)snowballing
C)systematic
D)stratified

Accepted Answer

Simple, systematic, and stratified sampling are all types of probability sampling procedures commonly used in research. Snowballing is a type of non-probability sampling where participants are recruited through referrals from other participants.

Question 4

In a ________sampling procedure, each individual in a population has a known probability or chance) of being selected for a study.
A)nonprobability
B)quota
C)probability
D)population

Accepted Answer

In probability sampling, every member of the population has a known chance of selection. This type of sampling is considered to be more representative of the population compared to non-probability or quota sampling. Population refers to the entire group of individuals that the researcher is interested in studying, and is not a type of sampling procedure.

Question 5

Samantha is conducting a survey to evaluate the eating habits of customers at fast food restaurants.She select the first 50 customers during the day as her participants.Samantha is using an) ________sample.
A)cluster
B)probability
C)biased
D)simple

Accepted Answer

Samantha's method of selecting the first 50 customers of the day introduces a bias, as this group may not be representative of all customers throughout the day, leading to a biased sample.

Question 6

While selecting participants for her study, Jamie draws names from a hat to place participants in groups.Once the participant's name has been selected, she does not put it back in the hat.Jamie is using________ .
A)sampling with replacement.
B)sampling with duplication.
C)sampling without replacement.
D)sampling without duplication.

Accepted Answer

Sampling without replacement means that once a participant's name is selected, it is not put back in the pool of potential participants. This is exactly what Jamie is doing, so her sampling method is without replacement.

Question 7

An) ________is a group of people representative of the population who are selected to participate in the research.
A)participant pool
B)experimental group
C)data group
D)sample

Accepted Answer

A sample is a group of people who are selected from the population to take part in a research study. The sample is chosen to represent the population as accurately as possible, and the data collected from the sample can be used to draw conclusions about the larger population. The other options are not accurate: a participant pool is a group of individuals who have indicated a willingness to participate in research studies; an experimental group is a group of participants who receive a specific manipulation in a research study; and a data group is not a commonly used term in research.

Question 8

Since it is not always possible to study an entire population of individuals, researchers will typically use an)________ .
A)participant pool.
B)experimental group.
C)data group.
D)sample.

Accepted Answer

Researchers will typically use a sample, which is a subset of the population, in order to make inferences about the larger population. This is often more practical and feasible than studying every individual in the population.

Question 9

In a ________probability sampling procedure, all individuals in a population have an equal probability of being selected.
A)cluster
B)convenient
C)simple
D)stratified

Accepted Answer

In a simple probability sampling procedure, all individuals in the population have an equal chance of being selected, which ensures the sample is representative of the population. Cluster, stratified, and convenient sampling may not guarantee equal probability of selection for all individuals in the population.

Question 10

By using ________, each selection in a study has exactly the same probability of being selected for participation.
A)sampling without duplication
B)sampling with replacement
C)sampling without replacement
D)sampling with duplication

Accepted Answer

Sampling with replacement ensures that each selection in a study has exactly the same probability of being selected for participation, as each member of the population is replaced after being selected, maintaining the probabilities for each draw.

Question 11

A sample in which not everyone in the population has an equal or known chance of being selected is called an)________ sample.
A)cluster
B)probability
C)biased
D)simple

Accepted Answer

In a biased sample, certain individuals or groups in the population are more likely to be selected than others, resulting in a non-representative sample. This can lead to inaccurate conclusions about the population as a whole. Cluster and simple samples are types of probability samples, which aim to give everyone in the population an equal chance of being selected. Therefore, they are not the best choices for a sample in which not everyone has an equal or known chance of being selected.

Question 12

In a study, Chris selected individuals by drawing names from a hat.Chris chooses one at a time and with each individual selected, he replaces the individual's name back in the hat before selecting the next individual.Chris is using ________.
A)sampling with replacement.
B)sampling with duplication.
C)sampling without replacement.
D)sampling without duplication.

Accepted Answer

Chris is replacing the name back in the hat before selecting the next individual, which means that each individual has the same chance of being selected in each draw. This is an example of sampling with replacement.

Question 13

Which of the following methods could be used in a simple probability sampling procedure?
A)pulling names of potential participants from a hat
B)placing people into groups as they enter an experiment
C)systematically separating the males from the females
D)identifying participants before the experiment starts

Accepted Answer

Simple random sampling is achieved when each member of the population has an equal chance of being selected. Pulling names from a hat is a common example of simple random sampling. The other methods listed do not offer equal chances of selection for each member of the population.

Question 14

In order to secure participants for his study, Jason uses class rosters from instructors.Jason selects every 5^th person on the instructor's class rosters for participation in his experiment.Jason is using________ sampling. A)simple B)snowballing C)systematic D)stratified

Accepted Answer

Jason is using systematic sampling, which involves selecting every kth individual from a list or population. In this case, he is selecting every 5th person on the class roster, making it a systematic sampling method. Simple random sampling would involve randomly selecting individuals from the roster without any set pattern, stratified sampling would involve dividing the population into subgroups and selecting individuals from each subgroup, and snowball sampling involves using referrals from existing participants to recruit new participants.

Question 15

The entire group of individuals in which you are interested in studying is called the________ .
A)sample.
B)population.
C)participant pool.
D)experimental group.

Accepted Answer

The entire group of individuals that the researcher is interested in studying is called the population. The sample is a subset of the population that is selected for the study. The participant pool refers to the individuals who have volunteered to participate in the study, and the experimental group is a group within the sample that receives a particular treatment or intervention in the study.

Question 16

Which of the following methods could be used in a simple probability sampling procedure?
A)placing people into groups as they enter an experiment
B)systematically separating the males from the females
C)using a random number table to put participants in groups
D)identifying participants before the experiment starts

Accepted Answer

Using a random number table to put participants in groups would be a valid method for a simple probability sampling procedure, as it involves randomly selecting individuals from the population of interest. Options A, B, and D do not involve a truly random selection process.

Question 17

Which of the following is a type of probability sampling procedure?
A)quota
B)stratified
C)convenience
D)snowballing

Accepted Answer

Stratified sampling is a type of probability sampling procedure where the population is divided into subgroups or strata based on certain characteristics, and a random sample is selected from each stratum. This ensures that the sample is representative of the entire population and reduces sampling error.

The other choices (quota, convenience, snowballing) are non-probability sampling procedures where the sample is selected based on availability or specific criteria, and may not be representative of the population.

Question 18

A researcher who places all potential participants for a study in a hat and randomly draws names for inclusion in their study is using a ________probability sampling procedure.
A)cluster
B)convenient
C)stratified
D)simple

Accepted Answer

The randomly drawing names from a hat is an example of a simple probability sampling procedure.

Question 19

When using________ , the probability of being selected for participation changes with each selection of a participant.
A)sampling without duplication
B)sampling with replacement
C)sampling without replacement
D)sampling with duplication

Accepted Answer

In sampling without replacement, once a participant is selected, they are not returned to the pool, changing the probability for subsequent selections.

Question 20

The two main sampling techniques that researchers use are ________sampling and ________sampling.
A)probability, population
B)population, quota
C)probability, nonprobability
D)quota, nonprobability

Accepted Answer

Probability sampling involves selecting participants randomly from the population, while nonprobability sampling does not involve random selection. Probability sampling is often considered more reliable and representative of the population, while nonprobability sampling may introduce bias into the sample. Therefore, the best choice is C, which includes both probability and nonprobability sampling techniques, acknowledging their respective strengths and weaknesses.
