Regression point analysis is done on the design of the regression point displacement which is made up on the statistical requirements such as including two groups having one group value equals to 1, pre test and post test values, dummy variables and model of covariance etc. regression point displacement model is also be called as the quasi experimental model. Thus from the stated model the analysis includes some requirements that are as follows;
• A post test values
• A pre test value
• The treatment group that is represented by specific variable.
This analysis is somehow similar to the analysis of covariance but there is the difference that it is treated on the single group variables. The analysis exists when the important measurements are already being there. As with the pre and post variables the analysis is practiced and then comparison is made with the existing measures. For the regression point displacement analysis can be made through the analysis of covariance and then regression equation is stated, that is:
yi = B0X+ B1Xi+ B2Zi+ei
