In the Correlation Coefficients area, select Pearson. In the Test of Significance area, select your desired significance test, two-tailed or one-tailed.
Which correlation test should I use?
Pearson correlation coefficient is most appropriate for measurements taken from an interval scale, While the Spearman correlation coefficient is more appropriate for measurements taken from ordinal scales.
What’s a good correlation coefficient?
The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement. A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation.
What is a strong correlation coefficient?
The relationship between two variables is generally considered strong when their r value is larger than 0.7. The correlation r measures the strength of the linear relationship between two quantitative variables.

How to write a regression equation using SPSS?
– ignoring these assumptions altogether; – lying that the regression plots don’t indicate any violations of the model assumptions; – a non linear transformation -such as logarithmic – to the dependent variable; – fitting a curvilinear model -which we’ll give a shot in a minute.
How to perform multiple linear regression in SPSS?
– run basic histograms over all variables. Check if their frequency distributions look plausible. – inspect a scatterplot for each independent variable (x-axis) versus the dependent variable (y-axis). – run descriptive statistics over all variables. – inspect the Pearson correlations among all variables.
