What is the difference between a population and a sample in research?

There is no difference between them

A population refers to a specific group, while a sample is a subset of that group

#14

In a factorial design, how many independent variables are manipulated?

One

Two or more

None

It depends on the specific design

1 answered

#15

What is the purpose of counterbalancing in experimental research?

To ensure that each participant receives the same treatment

To minimize the effects of extraneous variables

To control for order effects

To increase the generalizability of the results

1 answered

#16

What is the difference between internal validity and external validity in research?

Internal validity refers to the generalizability of findings, while external validity refers to the accuracy of measurements.

Internal validity refers to the accuracy of measurements, while external validity refers to the generalizability of findings.

Internal validity refers to the accuracy of measurements within the study, while external validity refers to the generalizability of findings beyond the study.

Internal validity refers to the generalizability of findings beyond the study, while external validity refers to the accuracy of measurements within the study.
