Expert Solution

1. A is false.

Ranges of bars are called class, not the bars of ranges.

2. C is false.

It is not necessary that all trendlines in a scatter diagram slope upwards.

3. B is correct.

A bar chart shows data by category.

4. The correct option is C- Pie charts are less clear than bar charts is comparing size of categories.

When two categories are close in size, its difficult for a pie chart to clearly show which one is bigger or smaller.
