mango1952,
An excellent brief description of the two types of hypotheses is
included in "Psychology 202Q PowerPoint Presentation #7", created by
Steven Rumery in 1998, updated by Poom Nukulkij in Fall 2000, and
located on the University of Connecticut's website:
H1 - The Alternative Hypothesis
"Refers to the expected finding that study variables will be related
in a meaningful way that is consistent with your theory and the
results of past research."
H0 - The Null Hypothesis
"Refers to the unexpected finding that study variables will not be
related in a meaningful way that is consistent with your theory and
the results of past research."
Examples of these two types:
"H1 = The more sleep a student has the night before an exam, the
higher their grade on the exam.
H0 = The amount of sleep a student has prior to an exam is not related
to their grade on the exam."
In other words, one type of hypothesis expects to find a correlation;
the other type expects to NOT find a correlation.
Rumery/Nukulkij's Presentation #7 contains an excellent explanation
and discussion on the two types of hypotheses; I encourage you to
check it out.
