Research method in which the psychologist observes the subject in a natural setting without interfering.
What is Naturalistic Observation
100
An educated guess about the relationship between two variables.
What is Hypothesis
100
A situation in which a researcher’s expectations influence that person’s own behavior, and thereby influence the participant’s behavior.
What is Self Fulfilling Prophecy
100
The branch of mathematics concerned with summarizing and making meaningful inferences from collections of data.
What is Statistics
100
A number that describes something about the “average” score of a distribution.
What is Central Tendency
200
Research method that involves an intensive investigation of one or more participants
What is a Case Study
200
The measure of a relationship between two variables or sets of data
What is Corelation
200
an experiment in which the participants are unaware of which participants received the treatment.
What is Single Blind
200
The listing and summarizing of data in a practical, efficient way
What is Descriptive Statistics
200
is the most frequent score. It a graphed frequency distribution, the mode is the peak of the graph.
What is Mode
300
A Research method in which information is obtained by asking many individuals a fixed set of questions.
What is a Survey
300
Any factor that is capable of change.
There are two types of
What is Variables
300
an experiment in which neither the experimenter nor the participants know which participants received which treatment.
What is a Double Blind
300
An arrangement of data that indicates how often a particular score or observation occurs.
What is Frequency Distribution
300
is what most people think of as an average and is most commonly used to measure central tendency
What is Median
400
Research method in which data are collected about a group of participants over a number of years to assess how certain characteristics change or remain the same during development
What is Longitudinal Study
400
The group that is treated in the same way as the experimental group except that the experimental treatment (the independent variable) is not applied.
What is control group
400
a change in a participant’s illness or behavior that results from a belief that the treatment will have an effect rather than from the actual treatment.
What is a Placebo Effect
400
___________ are very similar to bar graphs except that _________ show frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportionate to the corresponding frequencies.
What is Histograms
400
A measure of difference, or spread of data that provides an index of how spread out the scores of a distribution are.
What is Variability
500
Research method in which data care collected from groups of participants of different ages and compared so that conclusions can be drawn about differences due to age.
What is Cross - Sectional study
500
The group to which an independent variable is applied.
What is the experimental group
500
prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
What is Bias
500
are useful because they provide a clear picture of the shape of the data distribution and more than one set of data can be graphed at the same time.
What is Frequency Polygon/Curve
500
A measure of variability that describes an average distance of every score from the mean.
