Examples of Regression Hypotheses for BRFSS
In epidemiology, we say “hypothesis” a lot, but hypotheses are always posed as a statement. For example:
Following a low-fat diet lowers blood pressure in post-menopausal women.
Technically, you need a hypothesis (for the statistics part – the “alternative hypothesis”), but when you are writing, you might state it differently.
In writing, hypotheses can be stated as an aim:
The aim of this analysis was to determine if following a low-fat diet lowers blood pressure in post-menopausal women.
Or an objective:
Our objective was to examine whether following a low-fat diet lowers blood pressure in post-menopausal women.
Or a research question:
Does following a low-fat diet lower blood pressure in post-menopausal women?
