Question 1

Causal-Comparative Study

Answer 1

Research that seeks to determine the cause of differences between two groups based on an independent variable that has already happened or cannot be manipulated.

Question 2

Cluster Sampling

Answer 2

A sampling technique where the entire population is divided into groups and a random sample of these groups is selected

Question 3

Answer 3

The type of research that seeks to determine the degree to which a relationship exists between two variables

Question 4

Dependent Variable

Answer 4

The “outcome” variable—the variable through which a change or difference is measured

Question 5

Experimental Research

Answer 5

Research in which at least one independent variable is manipulated, other variables are controlled, and the effect of the independent variable on a dependent variable is observed

Question 6

Generalizability

Answer 6

The extent to which a sample represents the population from which it was selected

Question 7

Independent Variable

Answer 7

The variable believed to make a difference with respect to some behavior or condition

Question 8

Nominal Data

Answer 8

Classifies persons or objects into two or more categories

Question 9

Answer 9

Classifies participants by ranking them in terms of how much (or little) they possess a certain characteristic

Question 10

Population for a Study

Answer 10

The group to which a researcher would like the results of a study to be generalizable

Question 11

Qualitative Research

Answer 11

Research in which the investigator attempts to study naturally occurring phenomena, through means not involving traditional numerical data

Question 12

Quantitative Research

Answer 12

Research in which the investigator attempts to clarify phenomena through carefully designed and controlled data collection, generally involving numbers.

Question 13

Random Selecting

Answer 13

Selecting a group of individuals for a study in such a way that all possible participants have an equal and independent chance of being selected

Question 14

Reliability

Answer 14

The extent to which an instrument consistently measures what it is intended to measure

Question 15

Sample for a Study

Answer 15

A number of individuals selected for a study, preferably in such a way that they represent the larger group from which they were selected

Question 16

Sampling Bias

Answer 16

A bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others.

Question 17

Sampling Error

Answer 17

Chance variations that occur when a sample is selected from a population (not the fault of the researcher)

Question 18

Stratified Sampling

Answer 18

Selecting a sample in such a way that identified subgroups in the population are represented in the population in the same proportion they exist in the population.

Question 19

Systematic Sampling

Answer 19

Sampling in which individuals are selected from a list by taking every ___th name.

Question 20

Validity

Answer 20

The extent to which a test measures what it claims to measure
