Pearson correlation [Simply explained]

What is a Pearson correlation? The Pearson correlation analyses the linear relationship between two variables. With the help of the Pearson correlation coefficient r which is between -1 and 1 we can determine:
How strong the correlation is
and in which direction the correlation goes.

    is the strength of the correlation affected by sample size? if I took small sample out of the larger sample, would the strength of the correlation change?

    Thanks for the video! Though I'm slightly confued. Wouldn't the numerator always equal 0? As the sum of all values minus the number of values times the mean is 0, or is my math bad?

    This explanation is not very clear. Could nominal, ordinal scale use pearson correlation? As I know the mention scale cannot pearson but use Spearman Rank for ordinal....

    hmm, you can do it between two variables, you just want to know it there is a relation ship between the Variables. So if you want to know if there is a correlation between two dependent Variables for sure you can do it! Regards, Hannah
