Front

What is a histogram?

Back

A histogram is a type of graph that shows the distribution of a single variable by using bars to represent the frequency of data within certain ranges.

Front

What type of graph uses dots to represent values?

Back

A scatter plot uses dots to represent values and shows the relationship between two variables.

Front

What does a steady increase in a line graph indicate?

Back

It indicates that the data is increasing over time.

Front

How can you determine the highest temperature from a line graph?

Back

By looking for the highest point on the graph, which represents the maximum temperature.

Front

What does a cluster of points going upwards in a scatter plot suggest?

Back

It suggests a positive correlation between the two variables.

Front

What is a bar graph used for?

Back

A bar graph is used to compare different categories of data.

Front

What type of graph is best for showing parts of a whole?

Back

A pie chart is best for showing parts of a whole.

Front

What does a line graph represent?

Back

A line graph represents data points connected by lines, showing trends over time.

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 does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.
