FINAL ORAL RECIT

Question 1

Poor planning can lead to __________.

Answer 1

flawed experiments

Question 2

What are common causes of experimental failure?

Answer 2

1. Insufficient or irrelivant results
without proper design, the experiment might* not produce enough useful data.*

2. Excessive or Imbalanced Measurements
Taking too many measurements of some variables and too few of others can be problematic. Both scenarios waste resources and reduce the quality of conclusions.

Question 3

Consequence of Poor Design

Answer 3

Poorly designed experiments can result in:
Wasted time and resources, including samples and reagents.

Reduced quality of the conclusions that can be drawn from the experiment.

Question 4

Before beginning any experimental design it is crucial to _______________________________.

Answer 4

establishthe exact purpose of the proposed experiment

A failure to definesufficiently the objective of an experiment has led to the failure of asubsequent design.

Question 5

As a result the errors due to uncontrolled variation are ________________ since the errors in successive measurements are correlated

Answer 5

no longer random

correlated

Question 6

This can lead to a systematic error in the results

Answer 6

When uncontrolled variation are no longer random because the errors are correlated

Question 7

What is an experimental design?

Answer 7

A systematic plan for conducting an experiment.
