B) values
C) variables
D) central tendencies

Question 6

The extent to which the results of an experiment can be generalized from the sample that participated in it to a larger group of individuals, or population is known as ______.

A) sample reliability
B) population validity
C) population reliability
D) population reliability and validity

Question 7

Generally selecting a subset of individuals from the accessible population so that every single individual has an equal chance of being chosen and each selection is independent of the other selection is referred to as ______.

A) systematic random sampling
B) stratified sampling
C) convenience sampling
D) simple random sampling

Question 8

When the researcher can ensure that all in the population will be considered as part of the sample, based on the concrete list of the population then the researcher is using ______.

A) cluster sampling
B) stratified sampling
C) systematic random sampling
D) simple random sampling

Question 9

This type of sampling consists of selecting individuals from the population who represent subgroups, this is referred to as ______.

A) cluster sampling
B) stratified sampling
C) systematic random sampling
D) convenience sampling

Question 10

This type of sampling is used when groups of the target population may not be separated, this is referred to as ______.

A) stratified sampling
B) systematic random sampling
C) nonproportional sampling
D) cluster sampling

Question 11

A common approach used by researchers because many of the methods are more difficult to implement is known as ______.

A) simple random sampling
B) equal size sampling
C) cluster sampling
D) convenience sampling

Question 12

A suggested number of subjects per variable for correlational research is ______.

A) 25
B) 30
C) 35
D) 20

Question 13

According to Berg (2004), ______ sampling methods may be used in qualitative Research.

A) cluster
B) simple random
C) stratified sampling
D) all of these

Question 14

What specific number of subjects is suggested for conducting qualitative research?

A) 0
B) 15
C) 25
D) 25

Question 15

The best solution to the problem of sampling bias is the use of ______.

A) convenience sampling
B) random selection from the accessible population
C) cluster sampling
D) the use of stratified sampling

Question 16

To understand what a sample is, we must start with concepts defining the population.

Question 17

Most research involves populations that are quite small.

Question 18

Researchers have raised the issues of whether it is truly possible to select a sample that truly mirrors the population of interest.

Question 19

The extent to which a sample represents a population is critical in determining how easily and validly the researcher can generalize the result back to the entire target population.

Question 20

One of the advantages of simple random sampling is the results cannot readily be generalized back to the population.

Question 21

An important issue for researchers, regardless of the type of selection method used, is the use of volunteers.

Question 22

Almost all current researchers never use volunteers in their research.

Question 23

Typically researchers' propose 25 subjects per group in a research design.

Question 24

The stricter the level of significance, the more statistical power the researcher loses.

Question 25

Sampling error and sampling bias do not affect the validity of sample selection.

Question 26

Discuss the reasons the scientific community requires researchers to provide detailed descriptions of their methods in a journal article.

Question 27

Gall differentiated between two types of populations. They are ______.

Question 28

Discuss why it is practically impossible to include all members of a population in a study.

Question 29

Key in deciding which demographic characteristics to identify in a study are ______.

Question 30

Once a researcher identifies the population of interest, the next step is ______.

Question 31

Survey researchers should typically use a minimum of ______ per major subgroup.

Question 32

"The probability that a particular test of statistical significance will lead to rejection of a false null hypothesis" according to Gall et al. is known as ______.

Question 33

This type of sampling involves first identifying several people with relevant characteristics and interviewing them or having them answer a questionnaire. These subjects are then asked for the names of other people who possess the same attributes as they do. This type of sampling is known as ______.

Question 34

Define quota sampling.
