Q

What are the Cons of Experimental Research?

A

It is expensive & hard to set up, you have to ask for consent, it can look artificial, and can unintentionally overstep personal barriers such as personal space, other trauma, etc.

Q

What is Sampling Bias?

A

A bias where a sample is collected in a way that didn’t give everybody an equal chance of being selected.

20
Q

What is a Single Blind Experiment?

A

The experimenters know who is getting the treatment & not the subjects.

21
Q

What is a Double Blind Experiment?

A

Neither the experimenter nor the subject know who is getting the treatment.

22
Q

What is Placebo?

A

The belief that something is real or can affect you in some way but actually does not. Is most commonly used for medicinal testing.

23
Q

What is the Placebo Effect?

A

When somebody believes that they are being affected in some way because of a placebo treatment, when their false belief is enough to make them truly believe it’s real.

24
Q

What is Experimenter Bias?

A

When researchers treat members of the groups differently to increase the chance of confirming their hypothesis.

25
Q

What is the Hawthorne Effect?

A

An unnoticed bias, such as trying harder when the coach walks by.

26
Q

What are the advantages of Descriptive Correlational Research?

A

It is useful when experimentation is not possible, and has no ethical concerns.

27
Q

What are the disadvantages of Descriptive Correlational Research?

A

The Hawthorne Effect, Social Desirability Bias, Response Set, and the Halo Effect.

28
Q

What is a Case Study?

A

An in-depth study of a unique individual or extremely specific group.

29
Q

What is Naturalistic Observation?

A

The study of realistic behavior but has a major problem with the Hawthorne Effect.

30
Q

What is a Survey?

A

A collecting of opinions or attitudes

31
Q

What is Social Desirability Bias?

A

When a subject does not answer correctly to seem more socially desirable.

32

33

What is the Median?

A

The middle.

34
Q

What is the Mode?

A

The most abundant piece of data/info.

35
Q

What is Regression toward the mean?

A

If one sample of a random variable is extreme, the next sampling of the same random variable is likely to be closer to its mean.

36
Q

What is the Range?

A

The range of data points.

37
Q

What is Standard Deviation?

A

A measure of how dispersed the data is in relations to the mean.

38
Q

What is Positive Skew (Skew right)?

A

When the data lumps to the left and drops off to the right.

39
Q

What is Negative Skew (Skew left)?

A

When the data lumps to the right and drops off at the left.

40
Q

What is Correlation Coefficient?

A

A statistic ranging from 0 to 1 indicating the strength of the relationship. The farther the number is from 0, the stronger the relationship.

41
Q

What is Effect Size?

A

How meaningful the relationship between variables or the difference between groups is.

42
Q

What is Normal Distribution?

A

It helps to calculate percentile ranks on standardized tests.

43
Q

What is Statistical Significance?

A

When the results gained would very rarely occur by chance alone.

44
Q

What is the T-test?

A

An inferential statistic used to determine if there is a statistically significant difference between the means of two variables.

45
Q

What are the main flaws in research?

A

Ethics, Deception/Debriefing, Informed Consent, Animal Research, Confidential Information, Harm to the subject, Peer Review, and Replication.
