Question

. Discuss in detail about the expectation of sum of squares in C.R.D.​

Answer 1

Answer:

What Is the Sum of Squares?

Sum of squares is a statistical technique used in regression analysis to determine the dispersion of data points. In a regression analysis, the goal is to determine how well a data series can be fitted to a function that might help to explain how the data series was generated. Sum of squares is used as a mathematical way to find the function that best fits (varies least) from the data.

Answer 2

Answer:

Advantages of C.R.D

1. Very flexible design (i.e. number of treatments and replicates is only limited by  

the available number of experimental units).  

2. Statistical analysis is simple compared to other designs.  

3. Loss of information due to missing data is small compared to other designs due to  the larger number of degrees of freedom for the error source of variation.
