2. What is it?
Why is it
important for
good
research?
How do we
make sure
we have it
when
conducting
research?
What
prevents it
with regards
to research
structure or
design?
Provide this information about both
reliability and validity as they are related
to research:
3. 2. When methods or tools of
collecting data in a research are
reliable, we eliminate the number of
errors. Hence, each result is
accurate.
3. Every research must have a Pre-
planning which includes the types
of tools of measurement and their
reliability stability, equivalence &
homogeneity.
4. Outdated data gives reliable
results, because they are not
reflecting current situations.
1. Reliability is a trusted method or
test in the research field, so each
method gives the same results
every time its applied.
4. 2.When tools are valid, they give
results which are reflecting the
dimension it was measured. I.e.
when a test is used to measure job
candidates, its valid when it has a
direct relationship with future job
performance.
3. We must define what’s to be
measured and choose which tools
that gives valid responses or
results.
4. Some topics of research does not
suit specific tools of measurements
or collecting data, so tools becomes
invalid as they give inaccurate data
like: using questionnaires rather
than experiments to evaluate new
drug success rate on humans.
1.Validity is the likeliness of a
measurement to do its intended
purpose.
