  3. Correlation Coefficient Correlation coefficient a relationship is between two variables. s are used in statistics to measure how strong There are several types of correlation coefficient: Pearson's correlation (also called Pearson's R) is a correlation coefficient commonly used in linear regression.


  4. Correlation coefficient formulas are used to find how strong a relationship is between data. The formulas return a value between -1 and 1, where: . 1 indicates a strong positive relationship. . 1 indicates a strong negative relationship. . A result of zero indicates no relationship at all r 0 r0.4 Positive Correlation No correlation Negative

  9. Regression Regression is used to assess the contribution of one or more "explanatory" variables (called independent variables) to one "response" (or dependent) variable. It also can be used to predict the value of onee variable based on the values of others. When there is only one independent variable and when the relationship can be expressed as a straight line, the procedure is called simple linear regression.


  10. Linear regression equation (without error) b- slope rate of predicted values of Y predicted / for Y scores for each unit Y-intercept = level of Y when X is O increase in X
