25
Operational Definitions
Definition of what is being measured & how to be on the same page
26
Validity
Measures the goal for the measuring, accuracy
27
Reliability
Measured results can be repeated, or consistent each time
28
Sample
A smaller subpart of a population
29
Population
A group of objects/organisms belonging to a particular category
30
Representative Sample
A small random portion of a population that reflects the demographics of the whole one
31
Random Sampling
A random sample group with an equal chance of each person being selected
32
Experiment
A study in manipulating at least one variable while measuring at least one other variable
33
Confounding Variables
A variable that accidentally manipulates/interferes with the data
34
Random Assignment
Use of chance to place subjects in experiments & control groups
35
Controls
Altering conditions that influence behavior
36
Experimenter Bias
A researcher unconsciously affects results, data, or a participant in an experiment due to subjective influence
37
Double-Blind Procedure
Researchers & subjects don't know the status of the subject
38
Single-Blind Procedure
Only the subject doesn't know their group placement
39
Demand Characteristics
Cues that might indicate the study aims to the participants
40
Response or Participant Bias
Changes in behavior of the study participants that are caused by the unintended influence of their own expectations
41
Social Desirability
Tendency for people to present themselves in a generally favorable fashion
42
Hawthorne Effect
A participant's behavior changes as a result of being observed rather than as a result of an intervention
43
Placebo Method
A person's physical or mental health appears to improve after taking a placebo
44
Negative Correlation
Mathematical relationships in which increases are matched with decreases between ledgers
45
Positive Correlation
Either increase matches w/ increase or decrease matches w/ decrease in ledgers
46
Survey Method
Data collection tools used to gather information about individuals
47
Response Rate
Number of responses per minute, or some other time unit
48
Naturalistic Observation
A research method in which the researcher studies behavior in its natural setting without intervention of manipulation
49
Case Study Method
An in-depth investigation of a rare event of a single individual, family, event, or other entity
50
Mean (Measure of Central Tendency)
Average, calculated by adding all the scores and dividing by the number of scores
51
Median (Measure of Central Tendency)
Middle score between the higher & lower values
52
Mode (Measure of Central Tendency)
The most frequently occuring score
53
Extreme Scores/Outliers
Scores on the end of the data range that mess with the mean
54
Positive v. Negative Skew
Positive: both x & y increase or decrease, Negative: if x increases then y decreases & the opposite as well
55
Range (Measure of Variability)
Difference between highest & lowest values in a group
56
Standard Deviation (Measure of Variability)
How much a typical score differs from the mean score
57
Variance (Measure of Variability)
A measure of the spread, or dispersion of scores within a sample or population
58
Z Score
A raw score expressed in term of its position relative to the mean and in terms of standard deviation
59
Normal Curve
A perfect bell-curve that is symmetric about the mean
60
Correlation Coefficient
Index ranging from -1 to 1 indicating the direction & degree of correlation
61
Scatter Plot
A graph plotting random (x,y) measures
62
Line of Best Fit/Regression Line
A straight line that best illustrates the overall picture of what the collected data is showing
63
Inferential Statistics
Involves mathematical procedures that allow psychologists to make inferences about collected data
64
Sampling Error
Differences between what is present in a population and what's present in a sample
65
P Value
Probability under the assumption of no effect or no difference, of obtaining a result equal to or more extreme than what was observed
66
Statistical Significance
A measure of the probability of the null hypothesis being true compared to the acceptable level of uncertainty regarding the true answer

Process of sharing information & obtaining permission by subjects to perform an experiment
70

Process of disclosing information after an experiment in order to inform a subject of the purpose & results of the experiment
72
Null Hypothesis
Any observable differences in treatments or variables is likely due to chance
73
Type 1 Error
Reject the null hypothesis when it's true
74
Type 2 Error
Accept the null hypothesis when it's false
75
Nominal Data
Qualitative data grouping variables into categories, not quantitative or orderly, EX: license numbers
76
Ordinal Data
Categorical data with a set order or scale to it, EX: grades
77
Interval Data
Data measured in fixed units with equal distance between points on the scale, no true 0, EX: clock time
78
Ratio Data
Numerical values where the difference between points is standardized & meaningful where 0 is absolute, EX: heights
