WebMay 30, 2024 · p值是说在原假设成立的条件下,原假设发生的概率,若是p值小于0.05,发生概率小于0.05时,认为是小概率发生了,即是差异性显著,拒绝原假设。. 公式:. 双边 … WebP Value Calculator. Use this calculator to compute a two-tailed P value from any Z score, T score, F statistic, correlation coefficient (R), or chi-square value. Once you have obtained one of these statistics (from a publication or even another program) the P value helps interpret its statistical significance.
