A researcher would like to test the null hypothesis that the mean wait time at four urgent care
sites is equal. What statistical test should the researcher use in this situation?
ANOVA
The statistical tool used to compare more than two populations is called an analysis of

the National Health Information Infrastructure was defined further by the National Committee
on Vital and Health Statistics (NCVHS) in its report "Information for Health: A Strategy for
Building the National Health Information Infrastructure"
The application of information science to the management of healthcare data and information
