p-Value Calculator for a Student t-Test This calculator will tell you the one-tailed and two-tailed probability values of a t-test, given the t-value and the degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'....
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), ...
在统计分析中,T 值计算器是不可或缺的工具。T 值主要用于 T 检验,可比较两组数据的均值差异。无论是在学术研究、医学实验还是市场调研等领域,通过输入样本均值、样本标准差、样本量等数据,就能快速计算出 T 值。T 值计算器操作简便,结果精准,为数据分析提供有力支持,

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.
双尾χ²检验:p-value = 2 * min{cdfχ²,d(χ²score), 1 - cdfχ²,d(χ²score)} (Bywe 表示较小的数字和。min{a,b}ab 导致χ²分数的最流行的测试如下: 测试正态分布数据的方差是否具有某个预定值。在这种情况下,检验统计量具有具有自由度的 χ² 分布,其中样本数量。这可以是单...
