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 line of best fit represent in a scatterplot?

Back

A line of best fit represents the trend in the data and is used to make predictions about one variable based on the other.

Front

How can you determine the correlation from a scatterplot?

Back

You can determine the correlation by observing the direction and pattern of the data points: positive correlation (upward trend), negative correlation (downward trend), or no correlation (no discernible pattern).

Front

What does a positive correlation indicate?

Back

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

Front

What does a negative correlation indicate?

Back

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

Front

What does 'no association' mean in the context of a scatterplot?

Back

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

Front

How do you make predictions using a scatterplot?

Back

You make predictions by using the line of best fit to estimate the value of one variable based on the value of the other variable.

Front

What is the purpose of analyzing trends in a scatterplot?

Back

The purpose is to understand the relationship between the variables and to make informed predictions.

Front

What is an example of a situation where you might use a scatterplot?

Back

You might use a scatterplot to analyze the relationship between hours studied and test scores.

Front

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

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable.
