Scatter Plot Association

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables where each point represents an observation in the dataset, showing the relationship between the variables.

Front

What does a linear scatter plot indicate?

Back

A linear scatter plot indicates a straight-line relationship between the two variables, suggesting that as one variable changes, the other variable changes in a consistent manner.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or zero.

Front

What does a strong positive correlation look like on a scatter plot?

Back

A strong positive correlation is represented by points that are closely clustered around an upward-sloping line, indicating that as one variable increases, the other variable also increases.

Front

How can you identify a positive relationship in a scatter plot?

Back

A positive relationship in a scatter plot is identified when the points trend upwards from left to right, indicating that as one variable increases, the other variable also tends to increase.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, minimizing the distance between the line and all the points.

Front

What does it mean if a line of best fit is not accurate?

Back

If a line of best fit is not accurate, it means that the line does not adequately represent the trend of the data points, leading to misleading interpretations.

Front

What is a negative correlation?

Back

A negative correlation occurs when one variable increases while the other variable decreases, represented by points that trend downwards from left to right on a scatter plot.

Front

How does the age of a car relate to its value in a scatter plot?

Back

In a scatter plot showing the relationship between the age of a car and its value, the trend typically shows a negative correlation, indicating that as the age of the car increases, its value decreases.

Front

What is the significance of outliers in a scatter plot?

Back

Outliers are data points that fall far away from the general trend of the data, which can significantly affect the correlation and the line of best fit.
