Need to compare the means of two independent groups? Our T Statistic Calculator for Two Samples simplifies hypothesis testing, allowing you to quickly determine if differences between datasets are statistically significant. Input your sample means, standard deviations, and sizes to get immediate results for your two-sample t-test, perfect for research and data analysis.
Formula:
t = (x̄1 - x̄2) / √((s12/n1) + (s22/n2))
Where:
- x̄1: Mean of Sample 1
- x̄2: Mean of Sample 2
- s12: Variance of Sample 1 (square of standard deviation)
- s22: Variance of Sample 2 (square of standard deviation)
- n1: Sample Size 1
- n2: Sample Size 2
