3.1a - Scientific Method Flashcards
The steps of the scientific cycle?
- observation
- construct a testable hypothesis
- experimental design
- gather, analyse and record the data
- evaluate results and draw conclusions
- revise hypothesis if necessary
In science, refinement of ideas is the norm and scientific knowledge can be thought of the current best explanation which…
may then be updates after evaluation of further experimental evidence
The null hypothesis proposes that…
there will be no statistically significant effect as a result of the experimental treatment
Failure to find an effect (negative result) is a valid finding as long as…
an experiment is well designed
Conflicting data or conclusions can be…
resolved through careful evaluation or can lead to further experimentation
If there is evidence for an effect, unlikely due to chance…
then the null hypothesis is rejected
Scientific ideas only become acceptable once they have been…
checked independently
In experiments, effects must be reproducible, one-off results are…
treated with caution
