However we see from Table 2 that the median SAT Math Score of the students is 570. Since SAT scores range from 200-800, a score of 570 for Math may be considered as above average and meets the minimum requirement of some major public universities in the country. With this result, it is of further interest to see consider some factors which have effect on SAT scores. The dataset contains 7 variables namely: Student Identifier Number, GPA, Track Rank, Grade 8 Science Assessment Score, Grade 8 Language Assessment Score, Grade 11 Math Assessment Score and Grade 11 SAT Score for Math. It is of interest to determine the how these variables affect each other. Pearson's correlation, often denoted as r, can be used to compute for the degree of relationship two variables have with each other. The closer the value is to 1, the more associated the two variables are. Values for the Pearson's correlation coefficient may be either...However we see from Table 2 that the median SAT Math Score of the students is 570.

The closer the value is to 1, the more associated the two variables are. Values for the Pearson's correlation coefficient may be either positive or negative. A negative value for Pearson's correlation indicates that as the value of one variable goes up, the value for its associated variables goes down or vice versa. A positive value for Pearson's correlation indicates that the values for both variables increase and decrease together. It is computed as follows: Ho
