Statistical works and solutions - Coursework Example The correlation coefficient for this graph is 0.903293.The data are positively correlated and is closer to 1 which is perfectly correlated. This means that both data will reduce or increase all together. Correlation Coefficient determines the association of two variables and varies between will vary from -1 to +1(Wigmore, 2013). In negatively correlated variables, variables changes in opposite direction, while in positively correlated variables, both variables increase and decrease in the same direction. From above HPI and GDP, Ecological Footprint and HDI are positively correlated while the rest are negatively correlated In conclusion, the outcome from the graphs, result generated from excel, namely mean, media and Correlation Coefficient are closely related. The characteristics of the data can also be obtained from the variables using more than one method, either graphically or by calculation which is generated from the excel. Lastly, it is recommended to use more than one method when doing data analysis in order to come up with true interpretation of the results.
