New!May SlidesA.Where it is possible to predict, the values of one variable based on the values of the other,the relationship between the variables is described as a strong correlation.B.Where on average the values of one variable are related to another but there are many exceptionsthe relationship between the variables is described as a weak correlation.C.Pearson’s Product Moment Correlation ( r ) summarizes the the linear relationship and if the truerelationship is non-linear, the conclusions are incorrect.D.Correlations can be unreliable, especially with small sample sizes or large outliers, so the p-value is the standard way of quantifying the data.E. All of the above.3. What is correlation?
