Scatterplot Predictions

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional axis.

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 does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; the data points do not follow a clear pattern.

Front

How can you identify a trend line in a scatter plot?

Back

A trend line is a straight line that best represents the data points in a scatter plot, showing the general direction of the data.

Front

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

How do you make predictions using a scatter plot?

Back

You can make predictions by extending the trend line to estimate values for the dependent variable based on given values of the independent variable.

Front

What is the purpose of using a scatter plot?

Back

The purpose of using a scatter plot is to visually display the relationship between two quantitative variables and to identify trends or patterns.

Front

What does it mean if a scatter plot has a steep slope?

Back

A steep slope indicates a strong relationship between the two variables, meaning that small changes in one variable result in large changes in the other.
