Test for the level of associations among selected diseases infecting children in Nigeria

Abstract

This research tests for the level of associations among selected diseases infecting children in Nigeria. The techniques applied are parametric Pearson correlation and non-parametric Spearman Rank Correlation. These parametric and non-parametric techniques were used to determine the level of associations between two variables that is the level of association between the numbers of infected children in Nigeria by these diseases. The analysis was done using the Statistical Package for Social Science (SPSS) version 25 software. The results obtained were presented in a tabulated form for comparison purposes. Both the parametric Pearson and non-parametric Spearman Rank Correlation results showed some similar association between the two diseases and there exists a strong positive/negative association (almost perfect linear relationship) between Diarrhoeal and other diseases; Pertuss and other diseases; Tetanus and other diseases; Malaria and other diseases; Prematurity (Premature birth) and other diseases. The positive association showed the strength of the linear relationship between two diseases and the negative association indicates the direction of the association, whereby as one disease increases, the other decreases.
