Cards

Term
Science
Definition
A process or method for generating a body of knowledge
Term
Goals of Science
Definition
1.Description- accurate portrayal of phenomena of interest
2.Explanation- gathering information about what and why this phoneme exists
3.Prediction- anticipate events prior to occurrence
4.Control- be able to manipulate the conditions affecting behavior
Term
Theory
Definition
A set of interrelated constructs, definitions, propositions that present a systematic view of a phenomena. With the purpose of explaining and predicting this phenomena
Term
Criteria for a good theory (1/5)
1. Parsimony
Definition
ability to explain alot as simply as possible
Term
Criteria for a good theory (2/5)
2.precision
Definition
Specific and accurate in it's wording and its conceptual statements, so everyone knows what the predictions are
Term
Criteria for a good theory (3/5)
3. testability
Definition
Empirically verifiable
Term
Criteria for a good theory (4/5)
4.useful
5.Generativity
Definition
5. stimulate research that attempts to support or refute it's propositions
Term
1. Internal validity
2. external validity
Definition
1. Causality
2. generalization
Term
Research designs help to control for confounding//extraneous variables

1.Experimental Methods
Definition
Random assignment
Manipulation of Independent variables both help to increase INTERNAL VALIDITY
Term
Random assignment and manipulation are the keys to
Definition
1.controlling extraneous variables
2. ruling out alternative explanations
3. being able to draw casual inferences
Term
Experimental Method
1 Laboratory Experiments
Definition
Random Assignment
Manipulation of IV
Increase INternal Vadility
NOT GOOD FOR EXternal Vadility and Generalization
Term
Experimental Method
2.Field Experiments
Definition
Randomization
Manipulation of IV
NOT PRACTICAL OR FEASIBLE IN MOST ORGANIZATIONS
Term
Experimental Method
3.Quasi-Experiment
Definition
Common in IOP (Randomize by dept. instead of by an individual)
Some manipulation of IV
reasonable levels of Internal Validity
Term
Observational Method
Surveys
Definition
Most common data collection in IOP..
No causality or manipulation
Just used to describe the relationship
Term
Convergent Validity (coefficients)
Definition
The degree to which a measure of the construct is related to the measure of other similar constructs... should be able to converge with other information... HIGH CORRELATION between variables
Term
Divergent Validity (coefficients)
Definition
The degree to which constructs or dissimilar, there should be divergence, LOW CORRELATION
Term
Reliability
1.Test-Retest Method
Definition
Highest amount reliability- but people may not show up for the re-test
Term
Reliability
2. Equivalent Form method
Definition
Use form A/then form B... We can only say the forms are equivalent, so correlation less than test-retest
Term
Split-Half method
Definition
Use of statistical formulas, low reliability and low correlation
Term
DATA COLLECTION TECHNIQUES
1.naturalistic observation
2.participant observation
3.unobtrusive naturalistic observation
Definition
1.not popular in IOP
2.blends in
3.researcher tries not to draw attention
Term
DATA COLLECTION TECHNIQUES
Case studies
Definition
examination of an individual, group, company or society. Main purpose is DESCRIPTION// but is LIMITED IN EXTERNAL VALIDITY
Term
DATA COLLECTION TECHNIQUES
Archival Research
USED IN IOP
Definition
research relying on secondary data sets that were collected either for general or specific purposes identified by an individual or organization. Lack of control over the quality of the data is the chief concern with archival research.
Term
ARCHIVAL RESEARCH
USED IN IOP
Definition
had cross-sectional- collected at one point in time from a single group of respondents
longitudinal data- collected over long periods of time so changes in attitudes and behavior are examined
Term
TYPES OF DATA
Surveys
MOST FREQUENTLY USED IN IOP
Definition
selecting a sample of respondents and administering some type of questionnaire.
Term
TYPES OF DATA
Self-administered questionnaire
Definition
completed by respondents absence of an investigator by mail
common in field settings where employees are often asked about their attitudes and beliefs about jobs and organizations
1.easy to admister
2.can be handed out to large groups of people at the same time
3.participants are unknown

neg.
1.likely hood of returned surveys is low
2.conclusions can be inaccurate
3.cant have clarification if they dont understand a question
Term
TYPES OF DATA COLLECTING TECHNIQUESs
Interviews
Definition
more time consuming because they are done one- on -one.
1.respond rates are higher
2. questions can be answered
IN IOP INTERVIEWS ARE USED TO GATHER DATA ABOUT THE COMPANY FROM THE EMPLOYEES PERSPECTIVE
Term
ESM- EXPERIENCE SAMPLING METHODOLOGY
Definition
data collection approach that captures momentary attitudes and psychological states. Popular when studying emotions
Term
Reliability
internal consistency
Definition
should be around .70, but VADILITY IS also important
Term
Validity
Definition
the extent to which our test measures what we believe it measures and how well it predicts other things
Term
Construct validity
Definition
the extent to which a test measures the underlying construct it was intended to measure
Term
construct
Definition
an abstract quality such as intelligence and motivation that is not observable and difficult to measure
Term
predictive validity
Definition
the extent to which test scores obtained at one point in time predict criteria obtained at some later point in time// SAT and GRE examples
Term
concurrent validity
Definition
how well a test predicts a criterion that is measured at the same time the test is administered
Term
MEASURES OF CENTRAL TENDENCY
Mode
Definition
most frequent score in a distribution
Term
MEASURES OF CENTRAL TENDENCY
mean
Definition
most useful// average of scores
Term
MEASURES OF CENTRAL TENDENCY
Median
Definition
extreme scores do not affect
Term
VARIANCE
2.standard deviation
Definition
most useful measure of dispersion
2.the square root of r
68% 1 sd
99% 3 sd
Term
Correlation coefficient (r)
Definition
strength of the relationship between variables. provides direction and magnitude of relationship
Term
coefficient of determination (r2)
Definition
the percentage of variance in a criterion that is accounted for by a predictor. The overlap of the correlation
Term
Meta-analysis
Definition
used to conduct quantitative literature reviews. Helps to QUANTIFY the relationship between two variables.
Term
content Validity
Definition
the degree to which a test or predictor covers a representative sample of the quality being assessed. ex. is the test over the material from the book? Employees performance appraisal reflects all the important elements of his or her job
