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 correlation in a scatter plot 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 scatter plot indicate?

Back

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

Front

What does it mean if a scatter plot shows no correlation?

Back

It means there is no discernible relationship between the two variables, and the points are scattered randomly.

Front

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

Back

A positive correlation can be identified by a pattern where points slope upwards from left to right.

Front

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

Back

A negative correlation can be identified by a pattern where points slope downwards from left to right.

Front

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

Back

The slope indicates the direction and strength of the relationship between the two variables.

Front

What is the purpose of using scatter plots in data analysis?

Back

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

Front

What does it mean if the points in a scatter plot are tightly clustered?

Back

Tightly clustered points indicate a strong correlation between the two variables.

Front

What does it mean if the points in a scatter plot are widely spread out?

Back

Widely spread out points indicate a weak correlation between the two variables.
