Frequently Asked Questions
Why do we use tally marks in data handling?
Tally marks help us count large sets of items quickly and without mistakes by grouping numbers in sets of five.
How do I know what scale to choose for a bar graph?
Look at the given numbers and choose a scale (like 1 unit = 2, 5, or 10 units) that fits all values neatly on your graph paper without making the bars too tall or too short.
Do I need to use a pencil and scale for drawing bar graphs?
Yes, always use a sharp pencil and a ruler to draw neat axes, bars, and grid lines for all graphs in your exam.
