What are some examples of variable relationships in statistics?

In statistics, variable relationships can be classified as positive, negative, or no correlation. For example, height and weight often show a positive correlation.

Can you explain positive and negative correlations?

Sure! A positive correlation means that as one variable increases, the other also increases. A negative correlation means that as one variable increases, the other decreases.

What is an example of a negative correlation?

An example of a negative correlation is the relationship between the amount of time spent studying and the number of hours spent watching TV. More study time typically means less TV time.

How do you measure these correlations?

Correlations are often measured using Pearson's correlation coefficient, which ranges from -1 to 1. A value close to 1 indicates a strong positive correlation, while a value close to -1 indicates a strong negative correlation.
