(iii) How to answer Variant 1 and 2 Questions?

Variant 2: How to ensure the reliability of results of the experiment?.

Variant 1: Why is there a need to repeat the experiment a few times?.

(ii) Reliability question is often expressed in the following format: So, when we repeat the experiments and find the average of at least 3 sets of consistent data, the results collected will be more reliable. If you conduct an experiment just once, you could get an anomalous (uncertain) result.

(i) Why do we repeat experiments a few more times? In this article I will share with you two question samples on how to tackle questions involving the reliability of the experiment by using " 3 RE" Strategy ( REliable - REsults- REpeat).
