On Correlation

The word “Correlation” is used to denote the degree of association between variables. If two variables x and y are so related that variations in the magnitude of one variable tend to be accompanied by variations in the magnitude of the other, they are said to be correlated. In the present paper, considering the performances (of twenty students) on translation test (x) and on comprehension test (y), the author tried to show here the correlation between x and y by positing the bivariate data on a scattergram.
