Types of Research

Case Study, Meta Analysis, Naturalistic Observation, Correlation, Experimental

Generalizability

Ability to apple the outcome from the sample to the broad population

Case Study

In depth study, many tests, a single subject

Naturalistic Study

Observing the subject in its natural state

Meta Analysis

Researching existing research; combination of data, multiple studies.

Correlation

Relationship between variables, positive and negative correlation

Correlation Coefficient

Experimental

Cause and effect, causal relationship, control group and experimental group

Ethics

I Do Care About Research Participants

Informed consent

Participants know what will be happening; they can leave at any time

Assent

Not legal agreement because the subject is not 18

Debriefing

Summarizing of what was done after the experiment; offers the outcome after the research

Deception

You must provide a lot of debriefing after research; done under very specific circumstances

Confidentiality

Asks for little information; hides individual identity, but you could somehow figure out the identity of the subject

Anonymity

There is no way to figure out the identity of the subject

Institutional Review Board

Permission should be given before research start

Protection from Harm

Participants are protected physically and psychologically as much as possible

Central Tendency

Mean, Median, Mode

Measures of variance

Range and standard deviation

standard deviation

The average difference a point and the mean

Percentile Rank

statistical measure that indicates distribution

Line Graphs

Skewed, Normal, bimodal

Skewed left

negative

skewed right

positive

Average IQ

100

Average Standard deviation IQ

15

+1SD or -1SD percentage

34.1%

+2SD or -2SD percentage

13.6%

+3SD or -3SD percentage

2.1%

Regression to the mean

as more data is added average levels out; the closer to the ‘correct answer’ with more data

Statistical Significance

Proof that the independent variable MOST LIKELY caused the change in the dependent variable and not chance

The chance in statistical Significance

Confounding variable

Effect Size

Measures of the magnitude or meaningfulness of a relationship between two variables.
