# What does a strong positive correlation look like?

## What does a strong positive correlation look like?

A positive correlation—when the correlation coefficient is greater than 0—signifies that both variables move in the same direction. The relationship between oil prices and airfares has a very strong positive correlation since the value is close to +1.

## How do you explain no correlation?

Zero or no correlation: A correlation of zero means there is no relationship between the two variables. In other words, as one variable moves one way, the other moved in another unrelated direction.

## How do you describe Pearson correlation?

Pearson’s correlation coefficient (r) is a measure of the strength of the association between the two variables. The nearer the scatter of points is to a straight line, the higher the strength of association between the variables. Also, it does not matter what measurement units are used.

## What is a positive correlation in math?

When two sets of data are strongly linked together we say they have a High Correlation. The word Correlation is made of Co- (meaning “together”), and Relation. Correlation is Positive when the values increase together, and. Correlation is Negative when one value decreases as the other increases.

## What does a positive correlation indicate?

Positive correlation is a relationship between two variables in which both variables move in tandem—that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.

## How do you report Pearson correlation results?

1. Four things to report.
2. Test type and use.
3. Example.
4. Pearson’s r value and (possibly) significance values.
5. Just fill in the blanks by using the SPSS output.
6. Once the blanks are full…
7. Reference to your scatterplot.
8. Report your results in words that people can understand.

## What is a positive correlation graph?

The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship. If the data points make a straight line going from the origin out to high x- and y-values, then the variables are said to have a positive correlation .

## What is an example of a no correlation?

There is no correlation if a change in X has no impact on Y. There is no relationship between the two variables. For example, the amount of time I spend watching TV has no impact on your heating bill.

## What type of correlation does the scatter plot show?

We often see patterns or relationships in scatterplots. When the y variable tends to increase as the x variable increases, we say there is a positive correlation between the variables. When the y variable tends to decrease as the x variable increases, we say there is a negative correlation between the variables.
