Constructing Scatterplots- Grade 8 (12.9.24)

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

How do you interpret a scatterplot?

Back

To interpret a scatterplot, look for patterns, trends, and correlations between the two variables represented.

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 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 no correlation in a scatterplot mean?

Back

No correlation means there is no discernible relationship between the two variables.

Front

How can you predict values using a scatterplot?

Back

You can predict values by finding the trend line or using the existing data points to estimate the value for a given input.

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 and can affect the overall interpretation of the data.

Front

How do you determine the best fit line in a scatterplot?

Back

The best fit line is determined by minimizing the distance between the line and all the data points, often using linear regression.

Front

What is the x-axis in a scatterplot?

Back

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