Scatterplot Predictions

Front

What is a scatterplot?

Back

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

Front

What does a negative correlation in a scatterplot indicate?

Back

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

Front

What does a positive correlation in a scatterplot indicate?

Back

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

Front

What does it mean if a scatterplot shows no association?

Back

No association means that there is no discernible relationship between the two variables; the data points are scattered randomly.

Front

How can you predict values using a scatterplot?

Back

You can predict values by finding the trend line or pattern in the scatterplot and using it to estimate the value of one variable based on the other.

Front

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

Back

A trend line helps to summarize the relationship between the variables and can be used for making predictions.

Front

What is the significance of outliers in a scatterplot?

Back

Outliers are data points that differ significantly from other observations; they can affect the overall trend and predictions.

Front

How do you interpret the slope of a trend line in a scatterplot?

Back

The slope indicates the rate of change between the two variables; a steeper slope means a stronger relationship.

Front

What is the x-axis in a scatterplot?

Back

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

Front

What is the y-axis in a scatterplot?

Back

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