The following Time Series Plots show the changes in the number of boys and girls sitting the Grade Six National Assessment (G6NA) in Dominica from 2000 to 2015. The graph shows a definite decrease in the number of students over the years. 

These graphs have been created using SAS Programs. The first graph has been kept simple. The green line represents the number of boys and the orange line represents the number of girls. The second graph is statistically identical to the first with the exception of the Map of Dominica in the  background. 

Further Statistical Analysis can be done to investigate and explain this gradual decrease over the years of the number of students sitting the G6NA. ​​

Using PROC CORR for Correlation Analysis of Continuous Variables.

2/12/2014

PROC CORR is used for performing Correlation Analysis and originates from the word Correlation. It focuses on the measure of the strength of the linear relationship between two continuous variables. Let’s recall that continuous variables are a subset of quantitative variables and that they store numerical data that is measured on a scale that has an infinite number of values containing no breaks such as 234, 234.6 and 235.0.
