How to Perform a One-Sample T-Test in Excel

A one-sample T-test is a statistical method used to compare a sample mean to a hypothesized population mean. Excel's functionalities enable users to conduct this test through a series of calculated steps.

Calculate the Sample Mean

The initial step in a one-sample T-test is to compute the sample mean. This is the average value of the sample data you are testing against the hypothesized mean.

Calculate the Standard Deviation

The second step involves calculating the standard deviation, which measures the spread of the sample data around the mean.

Calculate the Standard Error of the Mean

Next, determine the standard error of the mean, which provides an estimate of the variability of the sample mean.

Calculate the Degrees of Freedom

Subsequently, calculate the degrees of freedom, typically the sample size minus one, which is used in determining the critical value and p-value.

Calculate the T-Statistic

The t-statistic is computed in the fifth step, involving the sample mean, hypothesized mean, standard error, and degrees of freedom.

Calculate the P-Value

The final step is to calculate the p-value using the t-statistic and degrees of freedom. This value helps determine statistical significance.
