Frequently Asked Questions
How do I group tally marks correctly?
You draw vertical lines for each count up to four. For the fifth count, you draw a slanted line across the first four to make a bundle of 5, which makes counting much easier.
How do I choose the correct scale for a bar graph?
Look at the given numbers in your data. Choose a scale (like 1 unit = 2, 5, or 10 items) so that the largest value fits easily on your graph paper without being too small or too huge.
Is it mandatory to use a pencil and scale for bar graphs?
Yes, all diagrams, axes, and bars in graphs must be drawn neatly using a sharp pencil and a ruler to score full marks.
