One sample t-test. Choose the one-sample t-test to check if the mean of a population is equal to some pre-set hypothesized value. Examples: The average volume of a drink sold in 0.33 l cans — is it really equal to 330 ml? The average weight of people from a specific city — is it different from the national average?

This calculates an independent-samples t-test. The independent-samples t-test compares two unrelated groups, such as an experimental group and a control group. Enter the means, standard deviations, and sample sizes for two groups.
T-Test Calculator for 2 Independent Means. This simple t-test calculator, provides full details of the t-test calculation, including sample mean, sum of squares and standard deviation.
The one sample t test, also referred to as a single sample t test, is a statistical hypothesis test used to determine whether the mean calculated from sample data collected from a single group is different from a designated value specified by the researcher.
Two sample and one sample t-test calculator with step by step explanation.
This calculator uses a two-sample t test, which compares two datasets to see if their means are statistically different. That is different from a one sample t test, which compares the mean of your sample to some proposed theoretical value.
One sample t test calculator can be used to find test statistic, p-value, critical value, decision and conclusion with step by step solution.
