Paired t-Test Calculator
Calculate a paired-sample t statistic from the mean and standard deviation of paired differences.
Calculate a paired-sample t statistic from the mean and standard deviation of paired differences.
Move between weighted summaries, t statistics, chi-square goodness-of-fit and one-way ANOVA calculations.
Calculate a weighted arithmetic mean from values and their non-negative weights.
Open calculatorCalculate the pooled standard deviation for two independent samples under the equal-variance model.
Open calculatorCalculate a one-sample t statistic and its degrees of freedom from summary statistics.
Open calculatorCalculate Welch’s two-sample t statistic and approximate degrees of freedom without assuming equal variances.
Open calculatorCalculate a paired-sample t statistic from the mean and standard deviation of paired differences.
Calculate the chi-square goodness-of-fit statistic from observed and expected category counts.
Open calculatorCalculate a one-way ANOVA F statistic from summary statistics for three independent groups.
Open calculatorCalculate a paired-sample t statistic from the mean and standard deviation of paired differences.
Enter compatible statistical values. The calculator validates the inputs and applies t = d̄ / (s_d / √n), with df = n − 1.
Variables: d̄ = Mean paired difference; s_d = Standard deviation of paired differences; n = Number of pairs.
Example: A mean paired difference of 3, difference SD of 6 and 16 pairs give t=2 with 15 degrees of freedom.
It is an educational tool for descriptive and inferential statistical calculations from supplied values or summary statistics.
No. Where a test statistic is calculated, the tool does not automatically replace study design, assumption checks, p-value interpretation, confidence intervals or subject-matter judgment.
