Z-Test
Prof. Fisher has given a method of testing the significance of the correlation coefficient in small samples. According to this method the coefficient of correlation is transformed into Z and hence the name transformation. The statistic Z given by prof. Fisher is used to test:
a.Whether an observed value of r differs significantly from some hypothetical value or.
b.Whether two samples values of r differ significantly,
For testing whether r differs significantly from zero the t- test is preferable.
In order to apply the test we have to calculate Z and by applying Fisher transformation and then calculate the value of the standard normal variate.
Z- ε / 1/√n-3
In this method variables beings studied are controlled by the investigator. In other the effect of one variable is observed while other relevant variables are held constant
These models are applied to the management ( planning controlling and scheduling ) of large scale projects. PERT/ CPM techniques help in identifying potential trouble spots in
