How do I enter data into SPSS for Pearson’s r and scatterplots?
Let’s start with an example
I’m going to use this example to help you understand how to enter the data. Suppose you want to find out if there is a relationship between the amount of water consumed (in glasses) and skin elasticity ratings (1-10 with 10 being the best). You select 5 participants. Each participant is given a different about of water and each is asked to rate their skin elasticity. Here are the data. You can see the how many glasses of water each participant drank and their personal ratings of their skin elasticity. Sonraki Sayfa »

What are Pearson’s r and scatterplots?
Pearson’s r
Sometimes we want to know whether two variables are related to one another. If they are related, we want to know how much. Is there a strong relationship between two variables or is it a weak relationship? What is the direction of the relationship?
When one variable goes up, does the other go down? Pearson’s r can help us with that. Pearson’s r is a statistic that helps you understand the strength of the linear relationship between two variables.
When r is…
- Close to 1, there is a strong relationship between your two variables.
- Close to 0, there is a weak relationship between your two variables.
- Positive (+), as one variable increases in value, the second variable also increases in value. This is called a positive correlation.
- Negative (-), as one variable increases in value, the second variable decreases in value. This is called a negative correlation.
Scatterplots
These are graphs that often accompany the Pearson’s r statistic. These graphs help us understand the relationship between the two variables. They have lots of dots. Each dot signifies a data point that represents values of both variables.
