How to design an experiment including replication, randomization and control.
The 20 identical swatches of cloths are grouped into two random groups and on group, detergent of new additive is used and on the other group, the detergent without the new additive is applied.
Given information:
A company wants to test the effectiveness of a new additive for the detergent.
20 identical cloths with dirt and stains are considered.
Explanation:
An Experiment is a study of cause-and-effect between the variables.
20 cloths should be considered in two groups.
Control:
The variation between the groups receiving different treatments should be limited to the varying factor and other conditions should be similar.
One group would receive the detergent with new additive and other group receives detergent without new additive.
Randomization:
Cloths are assigned to different groups randomly.
Replication:
The main effect should be observed in multiple colths for it to be statistically significant.
