Nursing - Research Paper ExampleThe p rate is less than 0.001 which indicates that the data obtained are statistically significant. This, therefore, means that whizz should decrease their caloric intake to keep a low BMI because a high BMI puts one at a risk of getting lifestyle diseases such as high blood pressure and type 2-diabetes.2) There is a very hefty link among BMI and HDL cholesterol because according to the results, the correlation coefficient is very close to -1.00 (0.794). The relationship is nevertheless negative meaning as the BMI of an individual increases, the level of HDL cholesterol decreases. The p value is as well less than 0.001 meaning that the results are statistically significant. Since it is healthy to have high HDL cholesterol levels, one should, therefore, aim at reducing their BMI to acceptable levels.3) The relationship between the caloric intake and age of the respondents is non strong as indicated by the correlation coefficient (0.129) which i s neither close to 1.00 nor - 1.00. The corresponding p value (0.588) in any case supports the results since it is far much greater than 0.001 indicating that the degree of significance is very low.4) Using correlations as a statistical test has got several shortcomings. The correlation does not mean a cause-and-effect link between variables and so cannot be used for certain research questions which seek to determine that kind of relationship (Munro, 2005). For instance, it does not show if an increase caloric intake leads to a high BMI or high BMI causes one to take fewer calories. It besides quantifies only the strength of the linear relationship and does not provide other details concerning the relationship between the variables. Correlations are also bivariate meaning they only compare two variables from two data sets at a time which may increase chances of making errors since this rarely occurs in reality (Trochim, 2006). This makes it unsuitable for researchers feeling for interconnected relationships
