Test correlation for significance

Test correlation for significance: If there is a correlation in the sample, it still has to be checked whether this correlation also exists in the population. The question therefore arises as to the amount above which a correlation coefficient can be considered statistically significant.

The significance of correlation coefficients can be checked with the help of a t-test. As a rule, it is tested whether the correlation coefficient is significantly different from zero, i.e. linear independence is tested. In this case, the null hypothesis is that there is no correlation in the population. In contrast, the alternative hypothesis assumes that there is a correlation.

As with any other hypothesis test, the significance level is first set, usually at 5 %. If the calculated p-value is below 5%, the null hypothesis is rejected and the alternative hypothesis applies.

Please make videos about Bayesian Statistics and specially calculating Statistical Power for Bayesian models. Thanks a lot from EGYPT.

I love your lecture, could you make an video ? how many type of statistic model exists ? how to group the statistic model and key usages of each model?

What will be the interpretation if I have negative correlation and when calculating the p-value, the results says that the variables are significant? Thanks!

r(10)=0.679, what is the 10 meaning here pls?

But the sad thing is that I need to buy it

But it is showing all blur cannot read anything😢

Hi, sorry, where did you get the significance level of 5% when you were evaluating the p value of correlation between age and salary, in the last example?
