Analyzing Graphs

Front

What is the dependent variable?

Back

The dependent variable is the variable that is measured in an experiment or study, and it is affected by changes in the independent variable. In the context of graphs, it is typically plotted on the Y-axis.

Front

Which axis is the dependent variable on (almost always)?

Back

The dependent variable is almost always plotted on the Y-axis of a graph.

Front

What is the independent variable?

Back

The independent variable is the variable that is manipulated or changed in an experiment to observe its effect on the dependent variable. It is typically plotted on the X-axis.

Front

Which axis is the independent variable on (almost always)?

Back

The independent variable is almost always plotted on the X-axis of a graph.

Front

What does a positive correlation in a graph indicate?

Back

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

Front

What does a negative correlation in a graph indicate?

Back

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

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, showing the relationship between them.

Front

What is the purpose of a trend line in a graph?

Back

A trend line is used to show the general direction or pattern of the data points in a scatter plot, helping to visualize the relationship between the variables.

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 dependent and independent variables.

Front

What is the significance of the Y-intercept in a graph?

Back

The Y-intercept is the point where the line crosses the Y-axis, representing the value of the dependent variable when the independent variable is zero.
