Answer:
Replication
Explanation:
The 3 main principles of experimental deisgn
1. Randomisation
2. Replication
3. Blocking
Replication
This has different definition. It is when a researcher repeats that is replicate research findings through correct use of operational definitions, procedures, etc.
A good research mut be replicated and it must result in the same or similar in terms of findings each time the experiment is performed.
It also implies that the treatment used in an experiment was used more than once in an experiment. It because allows us to estimate the inherent variability in the data. This allows us to know and judge if an observed difference in treatment was as a result that is it could be due to chance variation.
Replication is very important because when we have one experiment or treatments once, we would not know if the observed difference is due to the treatments or just random variability. But replication helps you to know the reason for the observed differences.
Answer: Each planet spins in an epicycle.
Explanation:
Aristotle and Ptolemy believed that the Earth was the center of the universe and all other planets and the sun rotated around it. Galileo, a very important figure in modern astronomy, disproved this by reporting his finds after using his telescope.
He noted that every planet spins in an epicycle around the sun which would mean that the sun was at the center and the planets rotated around it thereby disproving the Aristotle and Ptolemy.
I agree but what is your question regarding this statement?
