SPSS FOR BIOLOGISTS: Learn about Pearson Correlation Coefficient

SPSS FOR BIOLOGISTS:WHAT IS PEARSON CORRELATION COEFFICIENT?

The most common measure of correlation in stats is the Pearson Correlation. The full name is the Pearson Product Moment Correlation (PPMC).It is a test statistics that measures the statistical relationship, or association, between two continuous variables and shows the linear relationship between them.

WHAT ARE THE POSSIBILITIES?

1. A correlation coefficient of 1 means that for every positive increase in one variable, there is a positive increase of a fixed proportion in the other.
2. A correlation coefficient of -1 means that for every positive increase in one variable, there is a negative decrease of a fixed proportion in the other.
3. Zero means that for every increase, there isn’t a positive or negative increase.In simple words "no correlation".

AIM OF THIS TUTORIAL?

In this video, we try to explain about how to find out the correlation between different gene expressions of a patient sample.This way It is more understandable for a biologist to study the correlation between two different genes.
