Graphing Interpretation (Formative)

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 visualize trends over time.

Front

What does the slope of a line in a graph represent?

Back

The slope of a line represents the rate of change between the two variables plotted on the graph. A positive slope indicates an increase, while a negative slope indicates a decrease.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is being tested and measured in an experiment. It is dependent on the independent variable.

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.

Front

How do you identify the highest value in a data set represented in a graph?

Back

The highest value in a data set can be identified by locating the peak point on the graph, which corresponds to the maximum value of the dependent variable.

Front

What does it mean if a graph shows a downward trend?

Back

A downward trend in a graph indicates that as one variable increases, the other variable decreases. This suggests an inverse relationship between the two variables.

Front

What is the purpose of a bar graph?

Back

A bar graph is used to compare different groups or categories. It displays data with rectangular bars, where the length of each bar is proportional to the value it represents.

Front

What is the significance of the x-axis and y-axis in a graph?

Back

The x-axis (horizontal) typically represents the independent variable, while the y-axis (vertical) represents the dependent variable. Together, they provide a framework for plotting data points.

Front

What does it mean if two variables are positively correlated?

Back

If two variables are positively correlated, it means that as one variable increases, the other variable also increases. This is often represented by an upward slope in a graph.

Front

How can you determine the average from a graph?

Back

To determine the average from a graph, you can sum the values represented on the y-axis and divide by the number of data points.
