The probability of significance is less than 0.01, and the correlation between the two variables is very significant, expressed by "**".

The significant probability is less than 0.05, and the correlation between the two variables is significant, which is represented by "*".

The probability of significance was greater than 0.05, and there was no significant correlation between the two variables.
