In this video, I demonstrated how to calculate Pearson's Correlation Coefficient by Hand using real sampled data. I interpreted the results and showed how to report the correlation results.
This video is a practical illustration of the video I published on “How to Perform Pearson’s Correlation Analysis”. So, to fully understand the content of this new video as a beginner, you are please required to see or watch that video first. Please, click on this link below now to see the video:

10. How to learn statistical analysis by hand
Correlation is the statistical analysis that measures the strength and direction of the relationship between two variables. It is denoted by small letter "r". Correlation therefore discusses relationships specifically between two variables, so it is not a causal effect.
There is a lot to learn in this video, and I hereby encourage you to see or watch this video to the end.
However, it is unlikely that in these days and time, correlation analysis is calculated by hand.
So, in my next videos, I shall be showing you how to perform different statistical analysis, including Pearson's Correlation analysis using statistical software, SPSS.
