Question 5: Explain the steps involved in drawing a bar chart from raw data.

Answer: Step 1: Determine the scale based on data range. Step 2: Draw axes and label the categories and values. Step 3: Draw bars with heights proportional to data values. Step 4: Add labels and title for clarity.

Question 6: Identify the common mistake made when drawing a bar chart where bars are not aligned at the same baseline. How can it be corrected?

Answer: Common mistake: Bars start at different points on the baseline. Correction: Ensure all bars are anchored at the same baseline for accurate comparison.

Question 7: A bar chart shows that 12 students prefer reading fiction, 7 prefer non-fiction, and 5 prefer comics. Draw the chart using a scale where 1 unit in height equals 2 students.
