Correlation Essay Example | Topics and Well Written Essays - 750 words

Correlation - Essay Example A negative correlation means that the changes in the variables are not uniform. In other words, when one variable increases the other decreases and vice versa. The correlation between different variable are in different cases are analyzed here. This analysis basically relates to the internet subsidies in Public Schools. "Policymakers and analysts have argued that public schools are a natural place to teach underserved populations about computers and increase access to new technology." (Goolsbee & Guryan, 2003). The correlation between the variable A and variable B of school lunch program can be seen first. The variable A is the number of students who are eligible for school lunch. The variable B is the amount of funding received by the school. Different types of correlation can occur between these two variables. A positive correlation between the two variables means that adequate funds are received by the school in order to provide lunch for the students at the school.

Similarly a minimal correlation means that the schools don't satisfy the criteria only to certain extend and so they are not able to avail the benefits of the subsidy. Correlation between classrooms and student performance The intention behind connecting classrooms with the latest internet facility is to ensure better performance of the students. In this case the variable A is the number of classrooms connected with internet. The variable B is the performance of the students in the test conducted. The correlations between these two variables are very much relevant because the actual results of the spending are understood by this. A positive correlation means that the classrooms are connected with better internet facilities and the students are provided the most modern internet facilities in the classrooms and the performance level of the students is very higher in the test. This shows that the nation has benefited by investment in facilities. A negative correlation means the classrooms are connected with internet and the students does not show sufficient improvement in their performance. This is a failure. A minimal correlation means that there are neither internet facili
