PEARSON PRODUCT MOMENT CORRELATION COEFFICIENT Definition It is the measure of the linear correlation between two variables X and Y It is the measure of the strength of a linear association between two variables and is denoted by r. It tells you how strong the linear correlation is for paired numeric data e.g. height and weight. The Pearson correlation coefficient‚ r‚ indicates how far away all these data points are to this line of best fit. Development It was the imagination and idea of Sir Francis

Calculating correlation values for categorical data In order to find the correlation values for the fields in our data set‚ The Pearson Correlation Coefficient was used. This requires that the data in both fields be quantitative. But what if we were looking to calculate the correlation on two given fields that were say‚ numerical and categorical‚ or even both categorical. The Point Biserial coefficient is a special case of The Pearson Correlation Coefficient; it is a branch of PCC although they

Assignment: Interpreting Correlational Findings Following are brief summaries of correlational findings‚ in which variables were found to be significantly associated with each other. Your task is to determine which of the three major causal models (i.e.‚ interpretations) could account for each finding. Indicate in the table below‚ by placing an X in the appropriate space‚ which of these three models could provide a possible explanation. Place an X in the space only if you judge the causal
