Interpreting Graphs (H)

Front

What is a scatter plot?

Back

A scatter plot is a type of graph that uses dots to represent the values obtained for two different variables - one plotted along the x-axis and the other along the y-axis.

Front

What does the x-axis represent in a graph?

Back

The x-axis is the horizontal line on a graph that typically represents the independent variable.

Front

What does the y-axis represent in a graph?

Back

The y-axis is the vertical line on a graph that typically represents the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is being tested and measured in an experiment, often represented on the y-axis of a graph.

Front

What is an independent variable?

Back

An independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable, often represented on the x-axis.

Front

How do you interpret the data points on a scatter plot?

Back

Each point on a scatter plot represents an observation, with its position determined by the values of the two variables being compared.

Front

What does a positive correlation in a scatter plot indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What is the purpose of a line of best fit in a scatter plot?

Back

A line of best fit is used to summarize the relationship between the variables and can help predict values.

Front

What does it mean if a graph shows an increasing trend?

Back

An increasing trend means that the values of the dependent variable are rising over time.
