The goal is to establish the existence of a cause-and-effect relationship between two variables |
Experimental research strategy |
|
Must demonstrate that changes in one variable are directly responsible for causing changes in the second variable |
Experiment or true experiment |
|
Typically the independent variable is manipulated by creating a set of |
Treatment conditions |
|
The specific conditions that are used in the experiment are called the ————-of the independent variable. |
Levels |
|
All other variables in the city other than the independent and dependent variables |
Extraneous variable’s |
|
The possibility that two variables appear to be related when in fact they are both influence by a third variable that causes them to vary together |
Third variable problem |
|
Demonstrating the changes in one variable tend to be accompanied by changes in another variable simply establishes of the two variables are related the remaining problem is to determine which variable is the cause and which is the effect |
Directionality problem |
|
Consist of identifying the specific values of the independent variable to be examined and then creating a set of train and conditions corresponding to the set of identified values |
Manipulation |
|
An extraneous variable that is allowed to change systematically along with the two variables being studied. In the context of an experiment and extraneous variable that changes systematically along with the independent variable and has the potential to influence the deep and variable. It is an alternative explanation for the observed Relationship and therefore is a threat to internal validity |

Random process |
|
Is the use of a random process to assign participants to treatment conditions |

Is an additional measure to assess how the participants perceived and interpreted the manipulation and or to access the direct effects of the manipulation |
Manipulation check |
|
Is the creation of conditions within an experiment that simulate or closely duplicate the natural environment in which the behaviors being examined would normally occur |
Simulation |
|
Refers to the superficial usually physical characteristics of the simulation which probably have a little positive affect on the X ternal validity |
Mundane realism |
|
On the other hand concerns the psychologicalaspect of the simulation that is the extent to which the participants become immersed in the simulation and behave normally unmindful of the fact that they are involved in experiment. |
Experimental realism |
|
Is research conducted in a place at the participants or subjects perceive as a natural environment |
Field study |
|
Two or more variables are measured to obtain a set of scores for each individual. The measurements are then examined to identify any patterns and relationships that exist between the variables and to measure the strength of the relationship |
Correlational research strategy |

Scatterplot |
|
In which the data points in the scatterplot tend to cluster around a straight line |
Linear relationship |
|
Is used to describe and measure linear relationships when both variables are numerical scores from interval or ratio scales |
Pearson correlation |
|
A relationship that is consistently one directional either consistently positive or consistently negative |
Monotonic relationship |
|
Is used to measure and describe monotonic relationship from both variables our ranks from an ordinal score or have been transformed to ranks |
Spearman correlation |
|
Is the squared value of a correlation and measures the percentage of variables in one variable that is determined or predicted by its relationship with the other variable |
Coefficient of determination |
|
Is the second important factor for interpreting the strength of a correlation |
Statistical significance of a correlation |
|
In a correlational study a researcher often is interested in the relationship between two variables to use knowledge about one variable to help predict or explain the second variable in this situation the first variable is called the |
Predictor variable |
|
The second variable being explained or predicted is called the |
Criterion variable |
|
The statistical process of using one variable to predict another is called |
Regression |
|
The researcher observes and systematically records the behavior of individuals to describe the behavior |
Observational research design |
|
This process involves the direct observation and systematic recording of behaviors, usually as the behaviors occur in a natural situation |
Behavioral observation |
|
Requires repeated exposure until the observer’s presence is no longer a novel stimulus |
Habituation |
|
Categories of behavior to be observed. I said a behavior categories and a list of exactly which behaviors count as examples of each are developed before observations begin |
Behavior categories |
|
The degree of agreement between two observers who simultaneously record measurements of a behavior |
Inter-rater reliability |
|
Counting the instances for each specific behavior that occurs during a fixed time observation period. |
Frequency method |
|
Recording how much time in individual spends engaging in a specific behavior during a fixed time observation period |
Duration method |
|
Involves dividing the observation. Into a series of intervals and then recording whether a specific behavior occurs during each interval |
Interval method |
|
Observing for one interval, then pausing during the next interval to record all the observations |
Time sampling |
|
Involves identifying one specific event or behavior to be observed and recorded during the first interval, then shifting attention to a different event or behavior during the second interval and so on for the fall series of intervals |
Event sampling |
|
Involves identifying one participant to be observed during the first interval, then shifting attention to a different individual for the second interval, and so on |
Individual sampling |
|
Involves using the techniques of behavioral observation to measure the occurrence of specific events in literature, movies, television, programs, or similar media that presents replicas of behavior |
Content analysis |
|
Involves looking at historical records to measure behaviors or events that occurred in the past |
Archival research |
|
A researcher observes behavior in a natural setting as unobtrusively as possible |
Naturalistic observation or non-participant observation |
|
The researcher engages in the same activities other people being observed in order to observe and record their behavior |
Participant observation |
|
Is the observation of behavior in settings arranged specifically to facilitate the occurrence of specific behaviors |
Contrived observation or structured observation |
|
One criticism of rating scale questions is that whenever questions in a series have the same choices for responding, participants tend to use the same response to answer all or most of the questions. This tendency is called |
Response set |
|
These establish the endpoints of the scales |
Anchors |
|
Internet surveys similarly to mail surveys are subject to _______ Which means that the people who complete the surveys are a self-selected sample that may not be representative of the population |
