The following points should be kept on mind while choosing most suitable scale for drawing a graph.
# the difference between the highest and the lowest values of each quantity.
# the intermediate values of each quantity to mark the values on the graph
# to utilize the maximum part of the paper on which graph is to be drawn.

Introduction:
Choosing the right scale for drawing a graph is crucial in accurately representing the data. The scale determines the intervals and proportions used to plot the data points on the graph. It is important to select a suitable scale that effectively communicates the information without distorting the data.

Factors to consider:

1. Range of Data:
The range of data refers to the minimum and maximum values of the data set. The scale chosen should be able to accommodate all the data points within the given range. It is essential to select a scale that is neither too large nor too small, ensuring that all data points are adequately represented.

2. Intervals:
The intervals on the scale determine the spacing between each data point on the graph. The intervals should be evenly distributed and easily comprehensible. It is advisable to choose intervals that are multiples of 1, 2, 5, or 10 for easier interpretation. The chosen intervals should also be appropriate for the precision of the data being presented.

3. Proportions:
The proportions on the scale refer to the ratio between the units on the x-axis and the y-axis. It is important to maintain consistent proportions to accurately represent the relationship between the variables being plotted. A distorted scale can mislead the reader and result in incorrect interpretations.

4. Clarity and Readability:
The scale should be clear and readable to ensure easy understanding of the graph. The labels on the axes should be legible and appropriately sized. The chosen scale should avoid overcrowding the graph with data points or making it too sparse. It should strike a balance between providing sufficient detail and maintaining clarity.

5. Context and Purpose:
Consider the context and purpose of the graph while selecting the scale. Different types of graphs, such as bar graphs, line graphs, or scatter plots, may require different scales. The scale should be chosen to effectively communicate the intended message of the graph.

Conclusion:
Choosing the right scale for drawing a graph is vital in accurately representing the data. By considering factors such as the range of data, intervals, proportions, clarity, readability, and the context of the graph, one can select an appropriate scale that effectively communicates the information and avoids distorting the data.
