Question

Read the descriptions of two experiments below.

Answer 1

Answer: The correct answer is option B

Explanation:

In any experiment, number of observations is very important for the authenticity and/or reliability of the results.

Repeating experiment again and again eliminates the results which we can get by chance factor.

It reduces the errors percentage.

In contrast, if number of observations is very low, such as, one or two, then there are high probabilities that we get those results by chance. However, getting the same results again and again ensures that the hypothesis is correct and reliable.

Answer 2

B. Experiment 1, because it gave the same results every time
