Answer 2

• control
• treatment
• replication
• randomization

Question 3

treatment

Answer 3

variable being tested

Question 4

control

Answer 4

baseline for comparision

Question 5

replication

Answer 5

repeating treatments to confirm results

Question 6

randomization

Answer 6

assigning treatments randomly to avoid bias

Question 7

block design types

Answer 7

• completely randomized design
• randomized complete block design
• latin square design

Question 8

completely randomized design

Answer 8

treatments assigned randomly. used in uniform conditions

Question 9

randomized complete block design

Answer 9

blocks are perpendicular to the gradient, each block contains all the treatments randomized within it. ideal for fields with one gradient

Question 10

latin square design

Answer 10

treatments arranged so each appears once per column and row. used when 2 gradients exist

Question 11

pseudoreplication

Answer 11

where multiple measurements within the same plot are incorrectly treated as independent replicates
