Primer in statistics part 2

This is the second part of a two part series.

First, a guide in selecting the proper
statistical tests based on the research question will be laid out in
text and with a table so that researchers choose the univariable
statistical test by answering five simple questions.

Second, the
importance of utilizing repeated measures analysis will be illustrated.
This is a key component of data analysis as in many dental studies,
observations are considered repeated in a single patient (several teeth
are measured in a single patient).

Third, concepts of confounding and
the use of regression analysis are explained by going over a famous
observational cohort study.

Lastly, the use of proper agreement analysis
vs. correlation for study of agreement will be discussed to avoid a
common pitfall in dental research.
