Scatter Plots & Predictions Warmup

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 grid.

What does a trend line represent in a scatter plot?

Back

A trend line, or line of best fit, represents the general direction or pattern of the data points in a scatter plot.

How can you use a trend line to make predictions?

Back

You can use a trend line to estimate the value of one variable based on the value of another variable by finding where the trend line intersects with the desired value.

Front

What is the purpose of the line of best fit?

Back

The purpose of the line of best fit is to provide a visual representation of the relationship between two variables and to make predictions based on that relationship.

What does it mean if a line of best fit does not pass through the middle of the data set?

Back

It means that the line may not accurately represent the overall trend of the data, potentially leading to less reliable predictions.

What is the first step in creating a scatter plot?

Back

The first step is to collect and organize the data points that will be plotted.

Front

What does it indicate if the data points in a scatter plot are closely clustered around the trend line?

Back

It indicates a strong correlation between the two variables, suggesting that one variable can reliably predict the other.

Front

What is a positive correlation in a scatter plot?

Back

A positive correlation occurs when an increase in one variable corresponds to an increase in the other variable, resulting in an upward trend.

What is a negative correlation in a scatter plot?

Back

A negative correlation occurs when an increase in one variable corresponds to a decrease in the other variable, resulting in a downward trend.

Front

What does it mean if there is no correlation in a scatter plot?

Back

It means that there is no discernible relationship between the two variables, and changes in one do not predict changes in the other.
