Cards

Term
Basic Research
Definition
Clarifying underlying processes, carried out to increase understanding of fundamental principles
Term
Applied Research

Examines effectiveness of particular practices, practical application, solving practical problems and employs empirical methodologies.
Term
Characteristics of Scientific Research
Definition
Scientific Method- 1. Identify problem. 2. Define Problem. 3. Determine what information would solve problem (gather information or do research). 4. Organize information 5. Analyze information
Can be repeated, studied, and criticized
Term

What is a research problem? *
Definition
Questions that indicate gaps in our knowledge. Current ideas that are challenged by new hypotheses

Term
Construct

Term
Characteristics of a Good Research Question

Term
What is "Peer Review"?
Definition
self regulation process by group of qualified individuals within relevant field to evaluate research work and validity of work
Term
Describe the Literature Review Process*
Definition
Assessment of a body of work that pertains to a specific question.
1. locate other work dealing with area
2. evaluate this work in terms of relevance to research question
Term
Primary Source
Definition
Report results directly,
Term
Secondary Source
Definition
Publications where authors describe work of others (textbooks), report on or cite other sources

Created Ethical Principles and Guidelines for the Protection of Human Subjects in Biomedical and Behavioral Research, same as the National Research act.- Tuskegee
States- Respect for Persons, Beneficence, and Justice
Term
National Research Act
Definition
Created protection of human subjects in Biomedical and Behavioral research and regulates use of human experimentation in medical research- response to Tuskegee syphilis study
Term
Buckley Amendment
Definition
FERPA, 1974- Family Educational Rights and Privacy Act
Gives students access to their educational records and protects that information from being shared unknowingly
Term
Informed Consent Process
Definition
Legal procedure to ensure participants in student are aware of all the potential risks and costs involved in study. Inform of nature of treatment, risks, and benefits. Consent should be given voluntarily and participant may choose to leave.
Term
Confidentiality
Definition
after collection researcher makes sure no one has access to data collected, names of subjects are removed
Term
Anonymity
Definition
State of being unknown or unacknowledged
Term
**Levels of HSRB (IRB) review **
Definition
Category 1- Exempt- no risk to adults, no informed consent needed (Observation, anonymous survey)
Category 2- Expedited- minimal risk, oral consent (classroom research (children), individual or group behavior)
Category 3- Full- questionable elements to study, IRB meet required (Special populations, vulnerable individuals, deception, unusual equipment, intervention or invasive measurement)
Term
Vulnerable populations
Definition
Those who can not decide for themselves or are unaware of implications of research
IE- Children, Fetuses, Pregnant Women, Decisionally/Mentally impaired, Prisoners, Students
Term
When is deception appropriate?
Definition
Find other ways, if not possible, inform subject as soon as possible with sufficient explanation
Term
What is a conflict of interest?
Definition
Term
Variable
Definition
Something that changes with in a class of objects (Gender, ethnicity, etc)
Term
Constant
Definition
No variation within a class of objects
Term
Categorical Variable
Definition
Variables that describe a difference in quality (not degree), categories, qualitative variable
For example- male/female, race, religion, favorite type of...
Term
Continuous Variable
Definition
Quantitative variable, variable that differs in degree or #
For example- height, weight, IQ
Term
Nominal Variable
Definition
Groups data with no rank (gender, place of birth)
Term
Ordinal Variable
Definition
Ranks data, categorical (placement on test, socio-economic status, student rank)
Term
Interval Variable
Definition
Equal distance/differences between score/points, continuous variable (Test scores, personality scales)
Term
Ratio Variable
Definition
Equal differences/distance plus a true 0 point, continuous variable (weight, height, income, length, # of resources)
Term
Independent variable
Definition
Variable being changed, variables that affect change
(IE- exercise program changes to heart rate= IV=exercise program)
Term
Dependent Variable
Definition
Variable being acted upon, variable being changed by an intervention The hypothesized outcome variable.(IE- exercise program changes to heart rate= DV=heart rate)
Term
Extraneous Variable *
Definition
Variable that isn't controlled, try to control in research as much as possible (ex. personality, resources, $, etc)
Term
Hypothesis
Definition
Proposed explanation of a phenomenon, prediction of the outcome of a study based on theory
Term
Directional Hypotheses
Definition
Indication of the outcome in a specific direction (increase, decrease, positive relationship, negative relationship, etc)
Closed but more grounded, cuts out other possibilities
Term
Non-Directional Hypotheses
Definition
No specific prediction about outcome of study, less convincing but more open to change
Term
Representative Sample *
Definition
More narrowly defined populations are better described, more consistent, more cost effective
However, more difficult to generalize findings
Term
Generalizability *
Definition
More difficult to generalize if sample is taken from a smaller or more homogenous group
Term
Random sampling
Definition
(Thought to be best representation of population)
Simple, Stratified, Cluster
Every member has equal/independent chance
Term
Non-Random sampling
Definition
Convenience sampling (volunteers), purposive sample (specific population)
Term
Validity
Definition
Degree to which evidence and theory support eh interpretations of test scores entailed by proposed uses of test. Reliable if valid
Term
Measurement Validity
Definition
Ways we interpret and use measurements
Considered in terms of Validity
Term
Content Validity
Definition
Focus on what is on or not on measurement,
appropriate to populations, aligned with assessment, irrelevant content off
Term
Criterion Validity
Definition
Way we use scores in the world
Performance on a task predict real world
Driver's license= better driver, SAT scores high= smarter
Term
Construct Validity
Definition
Underlying cognitive skill reflected n the measurement score, what is trying to be measured
Term
Reliability
Definition
Not necessarily valid, consistency of measurements (can be measuring off target), accuracy of results
Term
Measurement Error
Definition
Always present, efforts should be made to account for and reduce
Term
How to test the reliability of a set of scores? *
Definition
test/retest, consistency measures
Term
Internal Validity
Definition
Errors because of researcher, what researcher does that can lead to mistakes in research measurements (10 items)
Term
Selection Bias and control
Definition
Subject characteristic threats (comparing unlike groups)
Control- be mindful, random sample and assignment, pretest, measure before and after
Term
Mortality and control
Definition
Systematic loss of participants (attrition), selectively limiting populations, shifts study
Control- take upfront measurement to see if loss is random or systematic, try to prevent loss, random assignment
Term
Location and control
Definition
Inconsistency of location may affect test/treatment, environment influences measurement, setting
Control- try to stay in the same place
Term
Instrumentation and control
Definition
Decay, once good not always good, nature of measurement shifts, data collector bias
Control- consistency of measurement, same data collectors, blind scoring
Term
Testing (Pre and Post) and control
Definition
Participants may figure out study or learn from original test
Control- use control group, be careful about inclusion/placement of instruments (test)
Term
History and control
Definition
Unrelated events to the treatment/test affect treatment/test
Control- avoid holidays, use control group, be mindful
Term
Maturation and control
Definition
changes occur with in sample populations due to natural occurrences that are confused with treatment/test (ie Kids learn naturally)
Control- comparison/control group, be mindful
Term
Attitudes of Subjects and control

Feeling special or different due to treatment/test
Control- equal special treatment, control group
Term
Regression to the Mean and control

Control- use comparison or control group
Term
