A subset of the population that is intended to represent, or stand in for the population.

Front (Question)

Representative sample

Back (Answer)

Accurately reflects the individuals, behaviors, and scores found in the population.

Front (Question)

Random sample

Back (Answer)

Each member of the population has an equal chance of being included. Best way to ensure fairness

Statistical procedures used to summarize, organize, and simplify data

Back (Answer)

Descriptive statistics

#12

Front (Question)

Techniques that allow us to study samples and then make generalizations about the populations from with they are selected

Back (Answer)

Inferential Statistics

#13

Front (Question)

Back (Answer)

Population size

#14

Front (Question)

The naturally occurring discrepancy, or error, that exists between a sample statistic and the corresponding population parameter

Back (Answer)

Sampling Error

#15

Front (Question)

How do you control for sampling error?

Back (Answer)

• Random Assignment • Increase Sample Size • Keep variability in each sample relatively small

#16

Front (Question)

A simple measurement of participants’ scored on two variables to determine if a relationship is present

Back (Answer)

Correlation method

#17

Front (Question)

The researcher actively changes or manipulates one variable to see if a relationship is produced

Back (Answer)

Experimental Method

#18

Front (Question)

Contestant

Back (Answer)

Is a characteristic that does not vary regardless of the constraints

#19

Front (Question)

Variable

Back (Answer)

Is a characteristic or condition that changes or has different values for different individuals

#20

Front (Question)

Independent Variable (X)

Back (Answer)

Changed or manipulated, the one who causes a change by the researcher or variable its self.

#21

Front (Question)

Dependent Variable (Y)
