This study examined the canonical correlation analysis on vital signs and demographic measures of 200 patients in the selected government owned hospital in Imo State Nigeria. Canonical correlation analysis focuses on the correlation between a linear combination of the variables in one set and a linear combination of the variables in another set. The objective of the study is to identify and quantify the association between two sets of variables. The data for this study were collected in an arrangement with the nurses of the selected government owned hospital in Imo State Nigeria. A total number of 200 patients were randomly selected and used for this study. An ethical approval was obtained from the Ethical committee of the selected hospitals. The consent of the subjects were sought and obtained and the consenting subjects were used by the patients, using the following inclusion criteria: They were normally balanced (i.e. the subjects were able to answer questions on name, age, sex, date of birth, marital status etc., consciously and correctly; All the patients (both in- and out-patients) within April 1, to April 18 2018 participated in this exercise, as the nurses did not allow them to know the rationale behind the vital signs and demographic measurements; Both male and female were recruited. The data for this study, which contain four criterion measures and three predictor variables, were analyzed using the “Stata” statistical software package. Based on the results obtained, and the hypotheses carried out, it was revealed that out of the three sample canonical correlations, the first two are significant, while the third one is insignificant. Finally, it was concluded that relationship exists between the vital signs and the demographic measures of the 200 patients.
