CORRECT ANSWERS
Types of Design Research - Answer- -Observational Studies
-Experiment
-Surveys
-Content Analysis
-Meta-Analysis
Observational Studies - Answer- Researchers are observing and measuring important
variables. Used to describe important variables or explore the relationships between
variables.
Experiment - Answer- Study in which the researcher manipulates levels of an
independent variable to determine its effects on a dependent variable
Survey - Answer- A research method in which a sample of people is collected and
asked questions. Can be used to measure behaviors, attitudes, and cognitions.
Content Analysis - Answer- a systematic, objective, and quantitative method of
measuring the manifest meaning of symbols (texts, visuals, photos, design, art, audio,
etc.)
Meta-Analysis - Answer- -Some topics have been studied extensively
-How to make sense of these many studies, which may produce conflict
-Researchers produce a quantitative summary of a number if prior studies
Critically Thinking - Answer- evaluating the quantity of evidence by considering
assumptions, definitions, and methods used to arrive at a conclusion
5 components of critically evaluating research - Answer- 1.) What is the source of the
research and the funding?
2.) What or who were the units in the study and how were the selected?
3.) What is the nature of the measurements?
4.) Does the article make a casual claim? (does X cause Y) and if so, is there another
variable that might be present an alternate explanation?
5.) what is the size effect reported (difference)?
, Relationships between variables - Answer- -Positive: /
-Negative: \
-Neutral: no correlation
Types of Variables - Answer- -Nominal
-Ordinal
-Interval
-Ratio
-Discrete
-Continuous
Nominal - Answer- Variables that can be placed into categories, no logical order
-ex: gender (male=1, female=0)
Ordinal - Answer- Variables that are placed into categories that have a natural/logical
ordering
-ex: Socioeconomic status, education level
Interval - Answer- logical order that have equal distances between levels within each
category, have no meaningful zero
ex: temperature in degrees F, 0 degrees F does not mean there is an absence of
temperature
The Scientific Method - Answer- A systematic/scientific approach to begin to solve a
problem
Scientific Method Steps - Answer- 1. Question
2. Research
3.Hypothesis
4.Experiment
5.Analysis
6.Conclusion
Theory - Answer- A set of statements about relationships between concepts with the
intention to explain some part of the world
-are abstract
-aim to explain
-are tested by derived testable hypothesis from theories
concept - Answer- An abstraction that describes a portion of reality
Variable - Answer- Things (attitudes, characteristics, behaviors) that change from unit to
unit (person, social group, unit of content)
Hypothesis - Answer- A statement about the relationship between variables
