Class 6Data HandlingData Handling
  • AThe categories or items being compared
  • BThe frequency on a numbered scale
  • CThe total of all data
  • DThe tally marks

Step-by-Step Solution

The -axis lists the categories (items), while the -axis shows the frequency on a numbered scale.
Answer: A) The categories or items being compared

Key idea: Bar graphs: precise comparisons

A bar graph uses bars of **equal width** but **different heights**. The -axis (vertical) shows the frequency on a numeric scale; the -axis (horizontal) lists the categories. Reading: line up the top of each bar with the -axis to find its frequency. Comparing: the tallest bar is the most common; the shortest is the least common. Bars are usually evenly spaced for clarity.
