Question

in presenting data that result from an experiment, a group of students show that most of their measurements fall on a straight diagonal line on their graph. however, two of their data points are \outliers\ and fall far to one side of the expected relationship. what should they do?
do not show these points but write a footnote that the graph represents the correct data.
average several trials and therefore rule out the improbable results.
show all results obtained and then try to explore the reason(s) for these outliers.
throw out this set of data and try again.
change the details of the experiment until they can obtain the expected results.

Explanation:

In scientific experiments, it is important to be honest and comprehensive in data - presentation. Outliers can provide valuable information about experimental errors, new phenomena, or limitations of the model. Hiding or discarding them is unethical. Changing details of the experiment to get expected results is also wrong. Averaging trials to rule out outliers without proper investigation is inappropriate. The correct approach is to show all data and explore the reasons for outliers.

Answer:

Show all results obtained and then try to explore the reason(s) for these outliers.
