Aim

The goal or objective of an experiment, what you want to find out.

Procedure

The method or process used to investigate the aim of an experiment.

IV (Independent Variable)

The variable that is changed or manipulated in an experiment, or the variable that is measured.

Operationalize

To clearly define and specify how a variable is measured or observed in an experiment.

Hypothesis

The predicted outcome or statement about the relationship between variables in an experiment.

Experimental/Alternative Hypothesis

The hypothesis that predicts a specific change or effect of the independent variable on the dependent variable.

Null Hypothesis

The hypothesis that states there is no impact or relationship between the independent variable and the dependent variable.

Control condition

A condition in an experiment that serves as a standard or comparison to which other conditions can be compared.

Lab

a controlled experiment conducted in an artificial setting with high control over variables.

Confounding Variables

Variables that may distort or hide the effects of another variable in an experiment, and cannot be controlled.

Demand characteristics

Clues or cues in an experiment that may lead participants to infer the researchers' expectations or purpose.

Single blind

An experimental design where participants do not know which experimental condition they will be assigned to.

Double blind

An experimental design where both researchers and participants do not know which experimental condition participants are in.

Artificiality

The extent to which experimental settings and conditions do not replicate real-world conditions.

Participant variability

Differences among participants in an experiment that may influence the results.

Researcher Bias

Errors or prejudices of researchers in the research process that may lead to potential inaccurate results.
