measures used to describe and summarize research
39
mean

41
mode
a statistic that represents the most commonly occurring score or value
42

Another word for normal distribution?
Bell curve
45
ethics
the rules governing the conduct of a person or group in general or in a specific situation—or more simply, standards of right and wrong
46
debriefing
the explanation of the purposes of a study following data collection
47
institutional review boards (IRBs)
organizations that evaluate research proposals to make sure research involving humans does not cause undue harm or distress.
48
quasi-experimental design
research method similar to an experimental design except that it makes use of naturally occurring groups rather than randomly assigning subjects to groups
49
Psychology comes in what 3 shapes scientifically?
Physical (chemistry) Biological (body, life) Social (interaction w. environment)
50
Psychology is considered a social science, but in 30 years it is predicted to be considered

Questions authority, open skepticism, intellectual honesty
52
Science is cumulative in what way?
Overtime you know more, its a process
53
What are some good examples of self reports?
Questionaries', interviews
54
What are some descriptive methods (observe/describe behavior)?
Self reports, quizological (psychological), behavioral (watch something like a tv for experiment)
55
What are the advantages of naturalistic observation?
You can watch events as how they really unfold
56
What are the advantages of laboratory observation?
You can manipulate experiment in labs
57
What is an example of a case study?
Studying a case that is rare, such as a photophobia (Fear of light), or studying a case specific to a particular group of people. A unique, in depth study overall
58
What are some cons with surveys?
People could lie
59
What is an example of correlational designs?
The correlation between the relationship of SAT scores and college GPA. (Remember, not intended to show 'causation' meaning that high sat does not mean high college gpa, just examining a correlation)
60
Why does correlation not mean causation?
Because while a might cause b, or b might cause a, a third variable not mentioned in the correlation may cause both a and b. example: more people die when ice cream sales are high. variable c: because in the summer more ice cream is sold.
61
How is correlation measured and what is its meaning?
Correlation is measured from -1 to 1. The Further away from zero, positive or negative, the stronger the correlation. If its zero, neither strong or positive, there's no correlation
62
What are the 5 provisions of the APA ethical guidelines that is regulated when psychologists research with humans?
Informed consent & voluntary participation Respect for persons Beneficence Privacy and confidentiality Information about the study and debriefing (explanation of purposes)
63
What is the state of ethical research with animals?
Very controversial. strict laws and stand standards govern treatment
