Front

What is a scaled bar graph?

Back

A scaled bar graph is a type of graph that uses bars to represent data, where the length of each bar is proportional to the value it represents.

Front

What does each bar in a bar graph represent?

Back

Each bar in a bar graph represents a category of data and its height or length shows the quantity or value of that category.

Front

How do you read a scaled bar graph?

Back

To read a scaled bar graph, look at the height or length of each bar and compare it to the scale on the graph to determine the value it represents.

Front

What is the purpose of using a bar graph?

Back

The purpose of using a bar graph is to visually compare different categories of data.

Front

What is the difference between a bar graph and a pictograph?

Back

A bar graph uses bars to represent data, while a pictograph uses pictures or symbols to represent data.

Front

How can you find the total number of items represented in a bar graph?

Back

To find the total number of items, add the values represented by each bar.

Front

What does it mean if one bar is taller than another in a bar graph?

Back

If one bar is taller than another, it means that the category represented by the taller bar has a greater value or quantity.

Front

What is a key in a bar graph?

Back

A key in a bar graph explains what each bar represents and may include the scale used.

Front

How do you determine how many more items one category has than another using a bar graph?

Back

To determine how many more items one category has than another, subtract the value of the shorter bar from the value of the taller bar.

Front

What is the scale in a bar graph?

Back

The scale in a bar graph is the set of numbers that shows the values represented by the height or length of the bars.
