In which step of the scientific method do we want to use graphs:
A. make a hypothesis
B. communicate results
C. asking questions
D. analyze data

Hint: The above problem can be resolved by using the fundamentals of the graphical analysis and the need and importance of drawing a graph. In general, the graphs are used to record the data. The record is then analysed, undertaking the evaluation of the data to obtain the conclusion in the form of a final result. Moreover, graphs are also used to analyze some specific points, where there is some variation in the practical value occurring in the context of expected results. Furthermore, the graphs are also used to maintain the records for a more extended period and obtain the data whenever required.

 Complete step by step answer:
The graphs are a particular type of drawing used by the analysts to carry out the observations regarding the data collected during experimentation. Then, these data are analysed to obtain a suitable conclusion.
Therefore, the scientific method step, for which graphs can be used, analyses the data

So, the correct answer is “Option D”.

Note:
Try to understand the concepts and the applications of graphs. The graphs are the necessary drawings that are used for scientific and research analytics. Consider an example of an experiment that requires five results for its outcome. During each analysis, when the point for each of the results is analysed, that particular result is then mentioned on the graph. In this way, the remaining four results are also highlighted, these pieces of information are known as the graphical information, and the method is known as the graphical approach.
