Scatter Plots

Front

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 positive association in a scatter plot indicate?

Back

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

Front

What does a negative association in a scatter plot indicate?

Back

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

Front

What does no association in a scatter plot mean?

Back

No association means that there is no predictable pattern between the two variables; changes in one variable do not affect the other.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a linear relationship between two variables, which can be positive, negative, or none.

Front

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

Back

A positive correlation is identified by points that trend upwards from left to right.

Front

How can you identify a negative correlation in a scatter plot?

Back

A negative correlation is identified by points that trend downwards from left to right.

Front

What does it mean if a scatter plot has a strong correlation?

Back

A strong correlation means that the points are closely clustered around a line, indicating a strong relationship between the variables.

Front

What does it mean if a scatter plot has a weak correlation?

Back

A weak correlation means that the points are more spread out and do not closely follow a line, indicating a weaker relationship between the variables.

Front

What is the significance of the slope in a scatter plot?

Back

The slope indicates the direction and steepness of the relationship between the two variables; a positive slope indicates a positive correlation, while a negative slope indicates a negative correlation.
