Lesson 1 Flashcards
Refers to the overall plan
and scheme for conducting
the study.
RESEARCH
DESIGN
The purpose of this design is to
describe the status of an identified
variable such as events, people or
subjects as they exist.
DESCRIPTIVE
RESE ARCH
DESIGN
They are also known as
longitudinal repeated-measure
studies. They are also referred to as
interventions, because you do more
than just observe the subjects.
EXPERIMENTAL
RESEARCH
DE SIGN
To collect, verify and
synthesize evidence
from the past to
establish facts that
defend or refute your
hypothesis.
HISTORICAL
RE SEARCH
DE SIGN
A process of getting information
from a proper subset of population.
describe the
population characteristic through
the values obtained from a sample
as accurately as possible.
SAMPLING
Detailed outline of which measurements
will be taken at what times, on which
material, in what manner, and by whom
that supports the purpose of an analysis.
SAMPLING PLAN
It refers to a sampling
techniques in which samples
are obtained using some
objective chance
mechanism.
PROBABILITY SAMPLING
This technique when there is
no way of estimating the
probability that each element
has of being included in the
sample and no assurance that
every element has a chance
of being included.
NON PROBABILITY SAMPLING
Are the data gathering
devices that will be used in
the study.
INSTRUMENT
RESEARCH COMPLETED INSTRUMENT
Rating scales
interview schedules/ guide
tally sheets
flowcharts
performance checklist
time and motion logs
observation forms
SUBJECT COMPLETED INSTRUMENT
questionnaires
self-checklist
altitude scales
personality inventories
achievement test
projective devices
sociometric devices
Refers to the extent to
which the instrument
measures what it
intends to measure
and performs as it is
designed to perform.
VALIDITY
TYPES OF VALIDITY
extent to which research instrument
accurately measures all aspect of a construct.
CONTENT VALIDITY
TYPES OF VALIDITY
extent to which a research
instrument or tool measures the intended
construct.
CONSTRUCT VALIDITY
TYPES OF VALIDITY
the extent to which a research
instruments is related to other instruments that
measure the same variables.
Criterion Validity
Relates to the extent to
which the instrument is
consistent. The instrument
should be able to obtain in
approximately the same
response when applied to
respondents who are
similarly situated.
RELIABILITY
ATTRIBUTES
OF RELIABILITY
the extent to which all the items
on a scale measure one construct.
INTERNAL CONSISTENCY
TYPES OF REALIABILITY
the consistency of results using an
instrument with repeated testing.
Stability or Test-Retest Correlation
