This document outlines an assignment for a statistics course. It includes 5 questions asking students to: 1) Define experimental design terms, 2) Explain experimental design principles, 3) Compare completely randomized and randomized complete block designs, 4) Conduct ANOVA and post hoc tests to analyze outputs from 3 processes, and 5) Find and solve a problem from a book about randomized complete block design. Students must complete the assignment by 26 April 2022 before 5:00 PM.

Assignment 1 (10%)
1. Define the following terms [2.5pts]
a. Experimental design
b. Biometry
c. Treatment
d. Factor
e. Post Hoc tests
2. List and explain the basic principles of experimental design [1pt].
3. What is the difference between the completely randomized design (CRD) and
randomized complete block design (RCBD) [1pts]?
4. Three processes A, B and C are tested to see whether their outputs are equivalent. The
following observations of outputs are made:
A: 10 ,12, 13 ,11, 10, 14, 15 ,13
B: 9, 11, 10, 12, 13
C: 11, 10, 15, 14, 12, 13
a. Carry out the analysis of variance and state your conclusion [1.5pt].
b. Conduct post Hoc test if necessary [1pt].
5. Find a problem from books in the library about randomized complete block design and
compute ANOVA table, and write conclusion [3pts].
