25
Naturalistic Observation
Observing a subject's behavior's w/in a scenario w/o interfering with them to obtain objective results
26
Operational Definitions
A statement/ term used to define research variables ( may include the procedure of a study
27
Placebo
A false treatment meant to determine if the actual treatment truly works or if the expectations are impacting the results. ( typically a s sugar pill)
28
Placebo Effect
The occurrence of people experiencing the effects of a treatment without truly recieving the treatment.
29
Professional Ethics
The set of moral principles applied to standard research, practice, and teaching conducted by pyschologists. Ensures resonable behavior and ethics when working with subjects and clients.
30
Qualitative Research/ Measures
Studies done while measuring behaivior without numbers and instead qualities. ( Ex; dialogue, body language, etc.)
31
Random Assignment
The randomization of placing subjects in an experimetnal group or a control (placebo group).
32
Replication
The process of repeating a study/ experiment to find if original results from an initial study repeatable and therefore reliable.
33
Single- Blind Study
A study where only participants are ignorant to the details of a study/ experiment
34
Social Desirability Bias
Bias occuring w/in a sudy when subject respond to survey's according to societal/ experimenter expectations rather than being truthful.
35
Structured Interviews
A research method where each particpant is asked the same questions in the same order. -> ensures consistency & reliable comparisons.
36
Survey
Research method where participants answer a set of questions to provide data regarding attitude, behaviors, and opinions.
37
Theory
A well sustained explanation of an aspect of the natural world or of humanity. Uses principles to organize/predict an event.
38
Validity
Determines how well a test measures what it was designed to measure
39
Bimodal Distribution
A data set with two distict modes ( reoccurring values of the highest quantitity)
40
Central Tendency
A statistical measure indicating a middle point in a data set. Mean, Median, and Mode are all measures of central tendency
41
Correlation
A statistical relationship between two variables. Does not indicate direct causation, but when one variable changes so does the other.
42
Convenience Sampling
Obtaining subjects for a study by asking for peoples participation based on easy accessibility & availabilty
43
Correlational Research
A type of research design done to assess a relationship between two variables. Typically lacks manipulation of the variables and doesn't establish a cause-and-effect relationship.
44
Correlational Coefficient
A statistical measure indicating the strength & direction of a relationship between two variables. Will be on a scale of -1 (neg correlation) to 1 Positive correlation
45
Directionality Problem
A limitation w/in correlational research where within a correlational relationship between two variables it is indgistinguishable which variable impacts the other.
46
Effect Size
Statistical measure indicating the magnitude/strength of the relationship between variables in a study.
47
Mean
Arithmetic Average ( overall avg)
48
Median
The middle value w/in a set of numbers.
49
Meta-Analysis
Statistical method where researchers combine results of multiple studies ( regarding the same topic) to draw clearer understanding and a reliable conclusion
50
Mode
Most frequently occurring value in a data set
51
Negative Correlation
A relationship where as one variable increases the other will decrease. A negative slope
52
Negative Skew
A distribution with more data points at the lower extreme causing the tail of the graph to lift on the left
53
Normal Curve
NORMAL CURVE= BELL CURVE Bell shaped distribution of data with scores clustered around the mean with less data to the extremes
54
Percentile Rank
The precentage of individuals w/in a group who scored at or below a certain score/individual on a test
55
Population
The individuals w/in a group of study
56
Positive Correlation
When one variable goes up so does the other ( positive slope)
57
Positive Skew
Data distribution where some extremely high values pull the data tail up towards the right.
58
Random Sample
A sampling where each member of the population of study is equally likely to be included in the study.
59
Range
The difference between the highest score in a data set and the lowest score in a data set.
60
Regression Toward The Mean
The statistical tendency where extreme scores/ outliers will become less extreme/ move towards the mean when re-measured.
61
Representative Sample
A group of subjects w/in a study that closely matches the population of study as a whole.
62
Sample
A group of individuals examined for a study/research
63
Sampling Bias
A flaw in a study where a research sample isn't representative of the larger population of the study.
64
Scatterplot
A graphed cluster of dots indicating data results.
65
Skew
The asymmetry of a data distribution. -> showing the data is not evenly spread around a central point/ the mean.
66
Standard Deviation
THE BELL CURVE; the overall difference from the mean in a set of data. Def; Statistical procedure done to determine the variation w/in results/ data set.
67
Statistical Significance
The measure indicating whether the results of a study are unlikely to be caused by chance.
68
Third Variable Problem
The tendency for a third variable outside the two being studied leads to a correlation/relationship between the initial two which is not genuine.
69
Variation
The degree to which individuals w/in a population are different from each other. ( diversity)
