Repeatability and Reproducibility (DONE)

Question 1

Why might repeats of the same experiment under the same exact conditions be slightly different to each other?

eg.
repeat 1: 46.54
repeat 2: 44.93
repeat 3: 42.65

Answer 1

Repeats of the same experiment under the same exact conditions might be slightly different to each other due to random error.

Question 2

What does it mean if a set of results are “repeatable”? (important one)

Answer 2

If a set of results are repeatable it means that if the original experimenter repeats the investigation using the same method and equipment they will obtain the same results.

(therefore the results are repeatable.)

Question 3

What does it mean if a set of results are “reproducible”? (important one)

Answer 3

If a set of results are reproducible it means that similar results are produced even when we have a different person investigating or use different equipment or techniques when carrying out the experiment.

Question 4

What does it mean if a set of results are NOT “reproducible”?

Answer 4

It means that if we have a different investigator or use a different technique or equipment we won’t get similar results. We will not be able to recreate the same results again.

Question 5

What does it mean if a set of results are NOT “repeatable”?

Answer 5

It means that if the original experimenter repeats the investigation using the same method and equipment they won’t get the same results. Therefore, not being repeatable.
