Hypotheses
Hypothesis:
An expectation about events based on generalizations of the assumed
relationship between variables
We say
events
because it can encompass anything and everything you
might do a Research Study on
It is an
expectation
not just an inquiry.
A.
Requirements of Hypotheses
a.
Hypotheses must state relationships between variables
a.i.
How one effects the other
a.i.1.
Example: The lower the tone of a communicator’s
voice, the more likely that communicator will be perceived
as trustworthy
B.
Hypotheses must be consistent with what is known in literature
a.
You better have a lot of data that enables you to make a claim
-----------------------------------------------------------------------------
Notes:
C.
Hypotheses must be testable
a.
You have to demonstrate that you can easily study something.
a.i.
If you can’t find a good way to test it, it may not be a good RQ
Example:
“Public speaking instruction improves self-=confidence better than oral interpretation
instruction”
vs.
Public speaking instruction increases self-confidence more than oral interpretation”
D.
Hypotheses must be clear, grammatical, and unambiguous declarative sentences
a.
Predictable
Declarative Statement:
are sentences that make claims rather than ask question, give
commands, or express wishes.
Example:
(Poorly Written) “Communicators in Latino families differ from
communicators in Anglo families”
This is extremely broad and there are going to be many exceptions. It is
ambiguous
