The t-distribution was discovered by W. S. Gosset and R.A. Fisher. The entries in Student’s t table entries are the critical values (percentiles) for the t distribution. The applications of Student’s t distribution are related to (i) the sampling distribution of the mean $\overline{x}$, (ii) the distribution of a difference …
Frequently, we measure two or more variables on each individual and try to express the nature of the relationship between these variables (for example in simple linear regression model and correlation analysis). Using the regression technique, we estimate the relationship of one variable with another by expressing the one in …
The design in which the levels of one factor can be applied to large experimental units and the levels of other factors to the sub-units are known as “split plot design“. A split plot experiment is a blocked experiment in which blocks serve as experimental units. After blocking the levels …
