Reading graphs- line, bar, circle

Front

What is a line graph?

Back

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is used to show trends over time.

Front

What does the y-axis represent in a graph?

Back

The y-axis is the vertical line on a graph that represents the values of the data being measured.

Front

What does the x-axis represent in a graph?

Back

The x-axis is the horizontal line on a graph that represents the categories or time intervals for the data.

Front

How do you read a bar graph?

Back

To read a bar graph, look at the height or length of the bars to determine the value they represent. Each bar corresponds to a category.

Front

What is a circle graph (pie chart)?

Back

A circle graph, or pie chart, is a circular chart divided into sectors, each representing a proportion of the whole.

Front

What is the purpose of a graph?

Back

The purpose of a graph is to visually represent data to make it easier to understand and analyze.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0,0).

Front

How can you find the total from a bar graph?

Back

To find the total from a bar graph, add the values represented by each bar.

Front

What does it mean if a line graph is increasing?

Back

If a line graph is increasing, it means that the values are getting larger over time.

Front

What does it mean if a line graph is decreasing?

Back

If a line graph is decreasing, it means that the values are getting smaller over time.
