Survey Method- it's the most common type of study in psychology. It measures correlation. It's cheap and fast, it requires a variety of ransom samples, and it has a low-response rate.

Naturalistic Observation- it's basically watching subjects in their natural environment. You do not manipulate the environment.

Correlation Coefficient- it measures the amount of a relationship. It has a range from -1 to 1. The relationship gets weaker the closer you get to zero.

Case Studies- a detailed picture of one or a few subjects. Tells a story, and is only descriptive research. Doesn't give us correlation data.
Statistics- the recorded results from a study.
Mean, median, and mode
Mean- average
Median- middle number
Mode- most common number
Descriptive Statistics- describes sets of data
Other Measures of Liability
Range- distance from highest to lowest number
Standard Deviation- the variance of scores around the mean

Hypothesis- explains the relationship between two variables
Independent variable- whatever is being manipulated
Dependent variable- whatever is being measured in the experiment
Operational definitions- explain what you mean in your hypothesis, how will the variables be measured in "real life" terms
Sampling- identify  the population you want to study, the sample must be representative of the population you want to study
Experimental method- looking to prove casual relationships, cause=effect 
Beware of confounding variables- a confounding variable is anything that could cause a change in B that is not A.
Hawthorne effect- just the fact that you know you are in an experiment can cause change.
Correlation method- expresses a relationship between two variables, does not show causation.
Survey method- most common type of study in psychology, measures correlation, cheap and fast, good random sample, low response rate.
Naturalistic Observation- watch subjects in their natural environment, do not manipulate the environment.
Correlation coefficient- a number that measures the strength of a relationship, range from +1 to -1, the relationship gets weaker the closer you get to zero.
Case studies- a detailed picture of one or a few subjects, tells us a great story, does not give us correlation data.
Mean- average the results
Median- subtract the lowest from the highest
Mode- occurs the most in a set of data
Single blind- the subject does not know of the experiment being conducted.
Double-blind- the subject and the researcher do not know of the study being conduced.
Longitudinal- observing a study of the course of years
Cross-sectional- looking over a variety of groups

Research Methods

Research Methods
Psychology is a science, it's based on research.
Hindsight Bias- the tendency to believe after learning the outcome, that you knew it all along.
Overconfidence- when people tend to think they know more than they do.
The Barnum Effect- the tendency for people to accept very general or vague characterizations of themselves and take them to be accurate.
Applied vs. Basic Research
Applied Research has clear, practical applications.
Basic Research explores questions that you may be curious about, but is not intended to be immediately used.
