The one-sample t-test calculator provides a p-value with step-by-step calculation, confidence interval, effect size, test power, outliers, distribution chart, and a histogram.
The one sample t test can be used to look for a difference in only one direction from the standard value (a one-tailed t test) or can be used to look for a difference in either direction from the standard value (a two-tailed t test).
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? Two-sample t-test
One sample t test calculator can be used to find test statistic, p-value, critical value, decision and conclusion with step by step solution.
