Nature of Inquiry and Research Flashcards
using research instruments such as focus groups and open-ended questionnaires,
qualitative research
qualitative research; inductive,
quantitative research; __________
deductive
Conducting quantitative research usually begins with a
_________
hypothesis
quanti uses this sampling to eliminate bias
random sampling
quanti has a _____ (#) sample size
large
systematically
describe a phenomenon and its characteristics.
Descriptive Research
most prevalent kind of
quantitative research.
Descriptive Research
Descriptive Research aims to know the “____________” of the population,
phenomena, or situation being studied.
what where when how
Two Types of Descriptive Research
Observational Research, Survey Research
Aims to describe the characteristics of a group
or population.
Survey Research
It simply observes a
specific aspect of behavior or social
phenomena by gathering quantitative data
without influencing the variables
Observational Research
method for determining the
relationship between two or more variables
Correlational Research
when one variable moves,
the other variable moves in tandem and the same direction.
positive correlation
inverse relationship
between the two variables
Negative Correlation
TRUE/FALSE
In Correlational Research, variables are not manipulated
TRUE
aims to test causal
hypotheses and establish cause and effect relationships
between the independent and dependent variables
Causal-Comparative Research
controlled setting that manipulates
the independent variable to see the effects on the
dependent variable,
Experimental Research
the cause-the factor the influences
the study’s outcome.
Independent Variable
is the effect-what happens due to the
independent variable; outcome
Dependent Variable
explains the causal link or connection between two other variables,
Intervening Variable or Mediating Variable
can positively or negatively impact the
association between two variables,
Moderating Variable
held constant during experiments to limit its effect on the outcome.
Control Variable
factors that affect the research outcome are intentionally not measured
Extraneous and Confounding Variable
label only
Nominal
-It provides an order or rank of the value.
Ordinal
-Numerical in scale which is the exact difference between
two values is known.
Interval
The measurements on a _____
scale become ordered and have equal intervals when there is a real zero point.
ratio
Height, Age, Weight.
Ratio
an IQ score for which zero would have no meaning,
Interval
sex, religion, race, country of residence,
Nominal
social class, job position,
Ordinal
