Which of the following is true of presenting data in a graph?
A. Descriptive labels for the two axes may or may not be used.
B. The right approach is to always use a scale that includes zero.
C. Labels for individual data points should always be included.
D. The title of the graph need not be given.
Answer - Option D- The title of the graph may not be given.
A Option is not correct because each axis needs a label, a descriptive label is needed to indicate which variable is being represented on the axis.
B option is not correct because each axis need a scale to plot the data. But the low point on scale may be zero or any round number but should be smaller than the smallest data point.
C option is incorrect because it is not compulsory to label the individual data points. It is used to make detail graph and it is very complex.
D Option is correct beacuse it is not compulsory to give title to the graph. Graph may either be titled or captioned. Caption is necessary to provide a brief description about the graph.
