Correlation, Scatterpoints, and Causations

Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together. A positive correlation means that as one variable increases, the other also increases, while a negative correlation means that as one variable increases, the other decreases.

Front

What is causation?

Back

Causation indicates that one event is the result of the occurrence of another event. In other words, causation implies a direct cause-and-effect relationship between two variables.

Front

What is the difference between causation and correlation?

Back

Causation implies a direct relationship where one variable causes the other to change, while correlation indicates a relationship where two variables change together but do not necessarily influence each other.

Front

What does it mean if two variables are positively correlated?

Back

If two variables are positively correlated, it means that as one variable increases, the other variable also tends to increase.

Front

What does it mean if two variables are negatively correlated?

Back

If two variables are negatively correlated, it means that as one variable increases, the other variable tends to decrease.

Front

What is a scatter plot?

Back

A scatter plot is a graphical representation of two variables where each point represents an observation. It helps to visualize the relationship between the variables.

Front

What does a scatter plot with a positive slope indicate?

Back

A scatter plot with a positive slope indicates a positive correlation between the two variables, meaning that as one variable increases, the other variable also increases.

Front

What does a scatter plot with a negative slope indicate?

Back

A scatter plot with a negative slope indicates a negative correlation between the two variables, meaning that as one variable increases, the other variable decreases.

Front

What is an example of causation?

Back

An example of causation is: 'The more I exercise, the more calories I burn.' Here, exercise directly causes an increase in calorie burn.

Front

What is an example of correlation without causation?

Back

An example of correlation without causation is: 'The more ice cream sold, the more drownings occur.' This does not mean that ice cream sales cause drownings; both may be influenced by warmer weather.
