    The T-value is then compared to a critical value from a T-distribution table, which is a table of pre-calculated values for different degrees of freedom. The degrees of freedom is calculated as n-1, where n is the sample size.

    Opportunities and Realistic Risks

      Where:

    • The sample size should be sufficiently large to ensure reliable results

        • A T-value greater than the critical value indicates that the sample mean is significantly different from the population mean. A T-value less than the critical value indicates that the sample mean is not significantly different from the population mean.
