P Value from T Score CalculatorThis should be self-explanatory, but just in case it's not: your t-score goes in the T Score box, you stick your degrees of freedom in the DF box (N - 1 for single sample and dependent pairs, (N1 - 1) + (N2 - 1) for independent samples), ...
Use the t-statistic calculator (t-value calculator or t test statistic calculator) to compute the t-value of a given dataset using its sample mean, population mean, standard deviation and sample size. Read further where we answer to the following questions: What is the t-statistic? How do ...

\[df = n_1+n_2-2=40+38-2=76 \] 以\(\nu=76、|t|=|-1.2508|=1.2508\) 为输入通过程序T Score to P Value Calculator计算,可得出\(P=0.21484\)。 确定结论 \(p=0.21484>\alpha=0.05\), 故不拒绝零假设\(H_{0}\),差异无统计学意义。没有充分理由说明两个乌龟物种的平均重量不相等。 Pyth...

Find the P-Value The next step is to find the p-value for the test statistic. The p-value is a measure of how “surprising” or “unlikely” some statistic would be given the particular assumptions that the analyst makes. In the case of these t-tests for differences in means, the p...
The p-value calculator calculates the p-value for Z score, T score, F score and Chi-square score.If you don't have the score you may use one of the following calculators that will compute the score and the p-value:One sample Z-test, Two sample Z-test, One sample T-test,Two-Sampl...
Use the t critical value calculator to find the critical value of t, f, & chi-square if you don’t know how to find critical value.

This simple confidence interval calculator uses a t statistic and sample mean (M) to generate an interval estimate of a population mean (μ).The formula for estimation is:μ = M± t(sM) where:M = sample mean t = t statistic determined by confidence level sM = standard error = √(s2/...
