# r to p Value Calculator

The main result of a correlation is called the correlation coefficient (r). It ranges from -1.0 to +1.0. The P-value is the probability that you would have found the current result if the correlation coefficient were in fact zero (null hypothesis). If this probability is lower than the conventional 5% (P<0.05) the correlation coefficient is called statistically significant. Here is the online r to p value calculator to calculate one, two-tailed p-value correlation probability.

## Calculate One, Two Tailed P-Value Correlation Probability

#### Formula:

t = __ r __
√[(1—r^{2})/(N—2)]
df = N-2
P (one and two tailed) = [ 1/ ( (√df) Β(1/2,df/2) ) ] lt->-t to t ∫ ( 1+ x²/df)^{(-(v+1)/2)} .dx
** Where, **
t = True Correlation
r = Observed (Pearson Correlation Coefficient) Value
N = Sample Size
df = Degrees of Freedom
x = t Value
The above r to p value calculator is designed considering the ease of use to the user and accuracy in the computation of the results. Just input the values, the tool will update you the results within the blink of an eye.
