Operational definition

Definition of an abstract concept used by a researcher to measure or manipulate the concept in a research study

Intuition

Common sense

Authority

Media

Empiricism

Knowledge through observation and experiment

Determinism

All behavior has an identifiable cause

Parsimony

Simple explanation is most accurate and concise

Testability

Ideas only tested through observation through scientific method

Basic research

Understand fundamental behaviors

Applied research

Helps solve real world problems

Randomization

Participants are randomly assigned to levels of the independent variable in an experiment to control for individual differences as an extraneous variable

Types of Manipulation

Presence/ absence


Bivalent independent variable


Presence/ absence

Presence or absence of treatment or gender

Bivalent independent variable

Simplest type of independent variable. Independent variable with two levels.

Comparison/ control

Control group

Manipulation

Variable that operate in an experiment

Reliability

Consistency, ability, and repeatability

Independent variable

What's manipulated or what's causing the change

Dependent variable

Measured or observed

Data collection techniques

Survey/ questionnaire


Interview


Archival data


Systematic observation

systematic observation

Observing behavior cognitive and biological

NOIR

Nominal

Interval


Ratio

Nominal

Ordinal

Ordered categories/ order of rank not equally spaced

Interval

Numerical response/ equally spaced/ likert scale

Ratio

Have absolute zero

Beneficence

Reduction of risk of harm to the participants and compared with the benefit of the study

Respect

Provides information about the study before it begins. Obtain voluntary consent from participant after they are informed

Justice

Selection of participants must be fair. All participant groups must have opportunity to receive benefits of research.

Stanford prison study

1973/ zimbardo wanted to know how roles are given and how they affect our behavior. Planned for two weeks ended earlier

Milgrams 1963 study

Electric shocker. Most people did highest voltage

IRB

Institution review board

Debriefing

Answer questions and risks/ reduce harm/ protect after they have left

Qualitative

Non numerical/ varies by class

Quantitative

Numerical varies about amount

Construct validity

Accurate measurement

Validity

Choice of measurement/ accuracy/ high construct validity

Cofounding variables

Other explanation besides what being measured

Experimental

Randomization/ Manipulation/ comparison and control/ cause and affect

Quasiexperimental

Type of research design where a comparison is made, as in an experiment but no random assignment of subject to groups occurs/ relationships between pre-existing variables

Nonexperimental

Describes and predicts/ no Manipulation/ no control

Internal validity

How well study demonstrates cause

External validity

How well it applies outside the study
