The formula for chi-square involves a few steps, summing the results of an expression to compare observed (O) and expected (E) values. Here is an example of a chi-square calculator tocompare expected and observed frequencies. You can use this page to calculate the P value from chi-square...
Use our p-value calculator to easily find a left-tailed, right-tailed, or two-tailed p-value for a z-score, t-score, chi-square, or f-value.
🙋 If you want to revise some basics from statistics, our normal distribution calculator is an excellent place to start. What is p-value? Formally, the p-value is the probability that the test statistic will produce values at least as extreme as the value it produced for your sample. It...

T分布主要用于小样本情况下的均值检验和置信区间估计,而F分布则用于方差分析和回归分析中的方差比率检验。T分布关注的是单个样本或两个样本的均值差异,而F分布则用于比较多个样本的方差差异。两者在统计推断中各有侧重,T分布更适用于均值比较,F分布更适用于方差比较。 秋水共长天 2024-09-05 T分布的双边检验和单...
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...
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), ...
Welcome to our t-test calculator! Here you can not only easily perform one-sample t-tests, but also two-sample t-tests, as well as paired t-tests. Do you prefer to find the p-value from t-test, or would you rather find the t-test critical values? Well, this t-test calculator ca...
