2. SAMPLING PROCEDURE
-In designing a sampling procedure, the
sample must be a good representative of the
population. The sample size and the technique
of selecting the sample must also be defined
clearly.
15. 4. Identify, locate, and choose an
instrument to be used in the data
collection.
-it is essential that the researcher
should have a clear view of the
instruments to be used in addressing the
objectives of the study.
16. 5. Describe the procedures for administering
the data collection.
- to ensure the smooth conduct of the data-
gathering process, a data-gathering protocol
must be instructed.
A protocol is a written document containing the
essential steps to ensure the objectives of the
purpose of the data gathering.
17. TYPES OF
INSTRUMENTS
Instruments are classified
as either researcher-
completed or participant-
completed.
RESEARCHER-
COMPLETED
INSTRUMENTS are
those that are
accomplished by the
researcher.
21. CHOOSING A
SUITABLE
INSTRUMENTS WHAT MAKES A RESEARCH
INSTRUMENT EFFECTIVE?
Two essential criteria must be
considered in selecting an instrument
for data collection. These are the
validity and reliability of the instrument.

23. WHAT ARE THE BASIC
STATISTICAL METHOD USED
IN ANALYZING RESEARCH
DATA?
26. DRAWING
INFERENCES
FROM
QUANTITATIVE
DATA
Generalizations or inferences on the
population of interest can be made
based on the data acquired from the
sample.
In inferential statistics, drawing
interferences is facilitated through
hypothesis testing using a test for
difference between means and a test
of relationship, or correlation.
27. INDEPENDENT DATA SETS are
those coming from two different
groups of research participants, be
they animate or inanimate.
DEPENDENT DATA SETS are
those coming from the same
group of research participants.
