Characteristics of Quantitative Research - (answer)numerical data (quantity);
hypothesis & research procedure are stated BEFORE data collection; large sample
size; rely on statistical procedure; low interaction with subjects; rely on
controlling, measuring, and generalizing; objective by nature
Quantitative Methods/Designs - (answer)survey research; correlational research;
causal comparative; experimental; single subject experimental
Sampling techniques for quantitative research - (answer)simple random; stratified;
cluster; systematic;
Simple random - (answer)(quant) selection using table of random numbers
,Stratified - (answer)(quant) selection based on dividing up into subgroups which
have roughly equal representation
Cluster - (answer)(quant) intact groups are selected as by classroom, efficient but
less representative
Systematic - (answer)(quant) take a population and select every Kth invidual i.e.
sample population = 100 and you select every 5th person on list.
Qualitative Research - (answer)*emphasis on words and feelings; *research
problems/methods evolve as understanding of topic increases; *smaller sample
sizes; *relies on categorizing & organizing data into themes or patterns to describe
& synthesize the data; *high level interaction with subjects; *many possible
contexts & meanings for different people; *subjective by nature
Qualitative Research Methods - (answer)observation/field notes; interviews: face-
to-face, phone, focus group; questionnaires; archival documents; journals;
audio/video
,Qualitative Sampling Techniques - (answer)intensity; homogenous; criterion;
snowball; random purposive
Characteristics of Action Research (comes out of qualitative research) -
(answer)*persuasive & authoritative b/c it's done by teachers for teachers;
*relevant b/c solves real world problems; *accessible b/c teachers already have
built-in audience as test subjects; *encourages school reform by providing an
action plan; *practical by nature (see ch20).
Selecting topics - Characteristics of good research topics - (answer)*researchable
(can be solved by collecting and analyzing data); *interesting enough to hold your
attention (love it); *significant (contributes to field of knowledge); *ethical (no
harm done); *manageable (keep it in scope)
How to write a good research question - (answer)*solvable by collecting data;
*cannot be answered with simple yes/no; *what is the effect of x on y (x is indep.
, Variable, y is dependent variable); *i.e. What is the effect of an after school reading
program (x) on students' reading comprehension scores (y)?
Purpose & function of literature review - (answer)*see what's already been done;
*reveals what needs to be done; *addresses the research questions; *provides
rationale for your hypothesis; *avoids mistakes of others; *may suggest ideas not
previously considered; *provide new direction to your research
Resource Identification Evaluation & Selection - (answer)*primary & secondary
sources; WGU library: books, articles, e-reserves, ERIC; *What was problem
statement?; *Who was studied?; *Where was source published?; When was source
published?; *How was study conducted?; *see ch 3 for more detail
5 types Hypotheses - (answer)1. Deductive, 2. Inductive, 3. Directional, 4. Non-
directional, 5. Null
