Question

A set of annual numerical data, comparable over the years, is given for the last $12$ years.
Consider the following statements:
$1.$ The data is best represented by a broken line graph, each corner (turning point) representing the data of one year.
$2.$ Such a graph depicts the chronological change and also enables one to make a short-term forecast.
Which of the above statements is/are correct?

• A. $1$ only
• B. $2$ only
• C. Both $1$ and $2$
• D. Neither $1$ nor $2$

Answer 1

The correct option is A $1$ only

The first statement is true as we can easily track the ups and downs of datat form 1 year to the next.

Statement 2 is false as the graph would require some kind of mathematical model to predict the short-term forecast and would not be helpful on its own.
