If the environment is a major concern for you, you might want to look at statistics project topic ideas such as ‘Plastic Pollution’. An expression (equation) is written to reflect the calculation required. Expand the Variables section. Phi Coefficient: Definition & Examples. To calculate correlation, one must first determine the covariance of the two variables in question. Next, one must calculate each variable's standard deviation. The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. In this study, language instruction was the independent variable (with two levels: phonics and whole language). Any other variables in your experiment build on or affect the independent or dependent variables. The example begins with two independent variables - one quantitative and one categorical.
