AP Psych AAQ

Experimental

Controlled environment (experimental and control groups) a treatment is given (IV) to see effects (DV)

Correlation

Measures a relationship between two variables, no cause and effect, measured through observation, survey, case study, and meta analysis

Observation

Gathering information by watching participants and quantifying a factor (usually wanting to be naturalistic)

Case Study

Longitudinal and cross sectional in depth study of individuals

Meta Analysis

Combining information from multiple studies that already existed

What are the options for point 1, research method?

Experimental, observational, case study, and meta analysis

Operational Definition

A measurement of your variable (find how they quantify the variable in the study- use evidence, don't "make one up")

Independent Variable

The treatment given to the experimental group

Dependent variable

How the participants responds to the IV

Confounding Variable

Other factors that affect the dependent variable other than the initial treatment

Third variable

A third factor that is affecting both variables (a confounding variables that is attributed to the rise or decline of both)

Graphs

Find evidence in the frequency distribution, scatter plot, bar chart, or normal curve

Mean

The average

Mode

The most frequent score

Median

The middle number

Range

Smallest number subtracted from the largest number (big-small)

Standard Deviation

A measure of variance in scores

Skewness

Asymmetry of scores, follow negative or positive tail

Statistical Significance

P value, cut off 5% (.05)

Correlation Coefficients

Pearson r, closest to 1 is cut off

Effect Size

Strength of the relationship between its variables

IRB

A reviewed and approved study

Informed consent

Told about the experiment prior to agreeing to participate

Informed assent

Parental authorization for those 12-18

Confidentiality

Nothing traced back to participants

Debriefing

Told about the true nature of the study after it is completed

What are the options for point D, ethical guidelines?

Informed consent, informed assent, protection from harm, confidentiality, debriefing

Protection from harm

Humans come before science
