  • DAnalysing the degree of relationship

Detailed Solution & Explanation

Graphic presentation of data involves representing statistical data in the form of graphs, charts, or diagrams. This technique is extremely helpful for visualizing trends, patterns, and fluctuations over time. By plotting data points representing a variable yt\displaystyle y_t against a time axis t\displaystyle t, it becomes easy to analyze changes at different points of time, such as tracking growth, seasonal variations, or long-term trends. For example, in a time-series graph, the coordinate (t,yt)\displaystyle (t, y_t) is plotted to observe the trend function y=f(t)\displaystyle y = f(t). Other options like cause-and-effect or degree of relationship are better analyzed using specific statistical tools like regression or correlation coefficient r\displaystyle r. Hence, **Option A** is the correct answer.
