It has been observed that in most cases, the nurses tend to use a multiple regression to examine the extent to which the linear model fits the available data. Nurses use these descriptive statistics without considering the assumptions that are linked with inferential statistics. It has been observed that nurses do not select a random sample. Bu they select a sample of their interest and convenience and then generalize the results to some abstract population (Polit & Beck 2012).
