Scatter Plot Correlations

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.

What does a positive correlation indicate in a scatter plot?

Back

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

Front

What does a negative correlation indicate in a scatter plot?

Back

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

Front

What does 'no correlation' mean in the context of scatter plots?

Back

No correlation means there is no apparent relationship between the two variables; changes in one variable do not predict changes in the other.

Front

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

Back

A linear relationship can be identified if the data points form a straight line or a pattern that closely resembles a straight line.

Front

What is the purpose of using scatter plots?

Back

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

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation implies that one variable directly affects the other.

Front

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

Back

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

Front

What is an example of a positive correlation in real life?

Back

An example of a positive correlation is the relationship between hours studied and test scores; generally, more study time leads to higher scores.

Front

What is an example of a negative correlation in real life?

Back

An example of a negative correlation is the relationship between temperature and the number of hot chocolate sales; as temperature increases, hot chocolate sales tend to decrease.
