Scientific method

Question 1

What is the scientific method?

Answer 1

• observation
• construction of a testable hypothesis
• experimental design
• gathering, recording, and analysis of data
• evaluation of results and conclusions
• the formation of a revised hypothesis where necessary

Question 2

what is the norm in science?

Answer 2

In science, refinement of ideas is the norm, and scientific knowledge can be thought of as the current best explanation, which may then be updated after evaluation of further experimental evidence.

Question 3

what is the null hypothesis?

Answer 3

The null hypothesis proposes that there will be no statistically significant effect as a result of the experiment treatment

Question 4

what is a negative result?

Answer 4

Failure to find an effect (a negative result) is a valid finding, as long as an experiment is well designed.

Question 5

how is conflicting data resolved?

Answer 5

Conflicting data or conclusions can be resolved through careful evaluation or can lead to further experimentation.

Question 6

when is the null hypothesis rejected?

Answer 6

If there is evidence for an effect, unlikely due to chance, then the null hypothesis is rejected

Question 7

when can a scientific idea become accepted?

Answer 7

Scientific ideas only become accepted once they have been checked independently

Question 8

what must effects be?

Answer 8

Effects must be reproducible; one-off results are treated with caution.
