In a Meeting with a Biostatistician to Go Over the Analysis

Essay

In a meeting with a biostatistician to go over the analysis plan for your grant, the biostatistician states, "Although you are primarily interested in the relationship between exposure to second-hand smoke (SHS) and birth weight, a simple comparison of the birth weights for the SHS groups is not appropriate. However, multiple linear regression or ANCOVA can be used to help answer your research question." Explain the biostatistician's statement.
