Why is it important for the vertical scale of a graph to start at zero?

Back

Starting the vertical scale at zero provides a true representation of the data, preventing exaggeration of differences.

Front

What does it mean if the x-axis of a graph does not have equal intervals?

Back

It means that the spacing between values is inconsistent, which can distort the visual representation of the data.

Front

What is the impact of using inconsistent scales on a graph?

Back

Inconsistent scales can mislead viewers by making certain data appear more significant or less significant than it actually is.

Front

What is the purpose of a graph?

Back

To visually represent data in a way that makes it easier to understand and analyze.

Front

What should you check for when evaluating a graph?

Back

Check for consistent scales, appropriate intervals, and whether the graph accurately represents the data.

Front

What is an example of a misleading graph?

Back

A bar graph where one bar is much taller than others due to a non-zero starting point on the y-axis.

Front

How can the choice of graph type affect data interpretation?

Back

Different graph types (e.g., line, bar, pie) can emphasize different aspects of the data, potentially leading to different interpretations.

Front

What is the definition of a line graph?

Back

A graph that uses points connected by lines to show how values change over time.

Front

What is a bar graph?

Back

A graph that uses rectangular bars to represent the quantity of different categories.
