OD. It allows scientists to interpret data visually.
The main reason for displaying data in a graph is to make the data more interpretable, accessible and easy to understand. Graphs allow scientists to visually represent the data and identify patterns, trends, and relationships that may be difficult to discern from the raw data or from a table. By displaying data in a graph, scientists can quickly and easily identify outliers, compare different data sets, and make predictions. Additionally, graphs are a powerful tool for communicating research findings to others, as they can be easily understood and interpreted by a wide audience, including scientists, policymakers, and the general public.
OA. It helps scientists identify errors in an experiment's design.
OB. It shows more data than a table does.
C. It proves the scientific validity of the hypothesis.
All these options can be useful too, but they are not the main reason for displaying data in a graph.
