Introducing Experiments (Unit 1; Lesson 3) Research Methodology

Question 1

Quantitative Data

Answer 1

numerical data

Question 2

Experiment

Answer 2

A method of determining whether a cause-and-effect relationship occurs between two variables

Question 3

Independent Variable (IV)

Answer 3

the variable the researcher deliberately manipulates

Question 4

Dependent Variable (DV)

Answer 4

The variable measured after the manipulation of the IV

Question 5

Operationalized

Answer 5

Variables must be written in a way that is clear what is being measured.

Question 6

Standardized

Answer 6

Procedures must have enough detail to be replicated

Question 7

True Experiment

Answer 7

A random selection of participants to the chosen conditions

Question 8

Hypothesis

Answer 8

A prediction of how the IV affects the DV

Question 9

Null Hypothesis

Answer 9

States that there will be no relationship between the two variables being studied and any change is based on chance

Question 10

Field Experiment

Answer 10

an experiment done outside of the lab, in the “real world:” they cannot be easily replicated, nor can they control for extraneous variables

Question 11

Lab Experiment

Answer 11

an experiment done under highly controlled conditions

Question 12

Quasi Experiment

Answer 12

participants are not randomly assigned, but grouped based on a trait or behavior. This type of experiment is used to study a specific variable.

Question 13

Natural Experiment

Answer 13

An IV that is environmental in nature and outside of the researcher’s control. Behavior is often measured before and after.

Question 14

Control Condition/Group

Answer 14

lacks any treatment or manipulation of the IV. People assigned to the control group serve as a comparison for tested group

Question 15

Random Allocation to Conditions

Answer 15

Participants are divided into specific groups at random
