Analyzing Bar Charts 📊

Bar charts compare data across categories. You must compare the height or length of bars.

Strategy

Identify Axes: What do X and Y represent?
Group Data: Similar trends, highs, lows.
Compare: Use superlatives (highest, lowest) and comparatives (higher than, double).

Sample: Fruit Sales

Prompt: The chart shows fruit sales in three regions.

Sample Excerpt: Apples were the most popular fruit in the North, with sales reaching 50 tons. In contrast, Bananas were the least favored, at only 10 tons. Meanwhile, the South showed a preference for Oranges, which sold twice as much as in the North.
