Therefore it is necessary to consider the order. Categorical data consists of counts of observations falling into specific classes. When describing trends in a report you need to pay careful attention to the use of prepositions.

Absence of standardized processing and heterogeneous study results limit its use in clinical practice. Determine whether a predictor variable has a statistically significant relationship with an outcome variable. Tables should be comprehensible and a reader should be able to express an opinion about the results just at looking at the tables without reading the main text.
