WebI used Python's scipy.stats.pearsonr and my output was: R = 0.6029721580250637 P-value = 0.0. I'm confused. The R tells me that there is quite strong positive correlation and (correct me if I'm wrong) P-value tells me that there is really small chance (p<0.0001) that I could get same kind of data if there is no correlation between the two ... WebJan 27, 2024 · Use this if its not specified in the problem statement. If the p-value came up to be lets say 0.20 (> α), It means that probability of students scoring an average lesser than 70% just by random chance is 20% and therefore insignificant. And if the p-value came up to be 0.03 (< α), then it means that probability of students scoring an average ...

WebAug 2, 2024 · 1 Answer. Floating point numbers (according to the standard 1 nearly all programming languages use) are stored with a certain number of bits in the mantissa, in the exponent, and with a sign bit. As such, floating point numbers can make a difference between zero and minus zero. In almost all applications, that doesn't make a difference. WebAug 8, 2024 · A common value for alpha is 5% or 0.05. If the p-value is below the significance level, then the test says there is enough evidence to reject the null hypothesis and that the samples were likely drawn from populations with differing distributions. p <= alpha: reject H0, different distribution. p > alpha: fail to reject H0, same distribution. shoretel 565 compatible headsets
