2
Q

Dependent variable

A

The item being measured

3
Q

Population

A

Group of interest to be started

4
Q

Representative sample

A

The degree to which a simple reflects the diverse characteristics of the population that is being studied

5
Q

Random sampling

A

Wave ensuring maximum representativeness

6
Q

Randomly assigned

A

Used to a sure that each group has minimal differences

7
Q

Single-blind design

A

So just do not know whether they are in the control or experiment group

8
Q

Double-blind design

A

Neither the subjects nor the researcher know who is in which group

9
Q

Placebo

A

Therapeutic object or procedure that causes the control group to believe they are in the experimental group actually contains none of the test material

10
Q

Correlation research

A

Assessing the degree of association between two or more variables which naturally for

11
Q

Confounding third variable

A

An unknown factor that is playing a role

12
Q

Clinical research

A

Often takes the form of Case studies

13
Q

Case studies

A

Intensive studies of a single individual in aims to unlock universal principles

14
Q

Generalization

A

Applicable to similar circumstances because of the predictable outcomes of repeated to tests

15
Q

Internal validity

A

Certainty with which the results of an experiment can be attribute it to the manipulation of the independent variable

16
Q

External validity

A

The extent of findings of the study that can be generalized to the real world

17
Q

Reliability

A

When the same results appear if the experiment is repeated

18
Q

Descriptive statistics

A

Summarize data

19
Q

Inferential statistics

A

Allows researchers to test offices about data and turn them how accurate they are

20
Q

Central tendency in statistics

A

Characterize the typical value in a set of data

21
Q

Normal curve

A

The bell shaped curve,

22
Q

Negative skew and statistics

A

When there are more exponentially small values and exponentially larger values

23
Q

Positive skew

A

Opposite, more exponentially larger values

24
Q

Standard deviation

A

Average dispersion of numbers around the mean

25
Q

Percentile

A

Express the standing of one score relative to all others and a set of data

26
Q

Correlation coefficient

A

Tributes how studies relate to one another

27
Q

Pearson correlation efficient

A

Descriptive statistics that describes linear relationship between two attributes

28
Q

Negative correlation

A

When scores decrease

29
Q

Positive correlation

A

When scores increased

30
Q

Inferential statistics

A

Determine our level of confidence and claiming that the set of data would be unlikely to occur at chance

31
Q

Null hypothesis

A

States that a treatment in no effect in an experiment

32
Q

Alternative hypothesis

A

States that a treatment did have an effect

33
Q

Alpha in statistics

A

Except the probability that the result of an experiment can be attributed to chance

34
Q

Type one error in statistics

A

He refers to an age difference exist when in reality there is no difference

35
Q

Type to error in statistics

A

Conclusion states that there is no difference when in reality there is a difference

36
Q

Type one error in statistics

A

Also referred to as p-value

37
Q

Ethics and research

A

Stanley Milgram’s obedience experiment was viewed as an ethical, since then APA as set forth standards for ethicality in experiments

38
Q

Informed consent

A

Participants in the study agree to participate after they’ve been told what the participation entails

39
Q

Debriefing

A

After experiment is concluded participants must be told the exact purpose of their participation in the research
