12.19: Scatter Plot Flashcardizz

Front

What is a scatter plot?

Back

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

Front

What does the line of best fit represent in a scatter plot?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, indicating the general direction of the relationship between the variables.

Front

How can you use a scatter plot to make predictions?

Back

You can use the line of best fit to estimate the value of one variable based on the value of another variable.

Front

What type of relationship is indicated by a downward sloping line in a scatter plot?

Back

A downward sloping line indicates a negative relationship, meaning that as one variable increases, the other variable decreases.

Front

What type of relationship is indicated by an upward sloping line in a scatter plot?

Back

An upward sloping line indicates a positive relationship, meaning that as one variable increases, the other variable also increases.

Front

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

Back

If there is no clear pattern, it suggests that there is no relationship between the two variables.

Front

How do you determine the strength of a relationship in a scatter plot?

Back

The strength of a relationship can be determined by how closely the data points cluster around the line of best fit; closer points indicate a stronger relationship.

Front

What is the purpose of using a scatter plot in data analysis?

Back

Scatter plots are used to visually assess the relationship between two variables and to identify trends, patterns, or correlations.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that fall far from the other points and can significantly affect the line of best fit and the overall analysis.

Front

How can you identify the line of best fit on a scatter plot?

Back

The line of best fit can be identified by drawing a straight line that minimizes the distance between the line and all the data points.
