1-Sample Equivalence TestStat > Equivalence Tests > 1-Sample
Use to evaluate the equivalence between the mean of a product or process and a target value. For example, you can test whether the strength of a new drug is equivalent to a target of 5mg/ml.
You can also evaluate whether the mean is greater than or less than the target.
Sample in a column: Choose if the sample data are in a column in the worksheet.
Sample: Enter the column that contains the sample data.
Summarized data: Choose to enter summary values for the sample size, mean, and standard deviation of the sample.
Sample size: Enter the number of observations in the sample.
Mean: Enter the mean of the sample.
Standard deviation: Enter the standard deviation of the sample.
Target: Enter the target value.
What do you want to determine? (Alternative hypothesis)
Lower limit < test mean - target < upper limit: Test whether the difference between the mean and the target is within the limits that you specify.
Lower limit: Specify the lowest value for the difference that you consider functionally equivalent (for example, -0.2).
Upper limit: Specify the highest value for the difference that you consider functionally equivalent (for example, 0.2).
Multiply by target: Check to specify that the limit represents a proportion of the target. For example, check to specify the limit as 0.2 multiplied by the target, rather than as the fixed value of 0.2 grams.
Test mean > target: Test whether the mean is greater than the target.
Test mean < target: Test whether the mean is less than the target.
Test mean - target > lower limit: Test whether the mean is greater than the target by a specific amount. For example, you can test whether the mean weight of the population is at least 0.2 grams greater than the target.
Lower limit: Specify the lower limit to test (for example, 0.2).
Multiply by target: Check to specify that the limit represents a proportion of the target. For example, check to specify the limit as 0.2 multiplied by the target, rather than as the fixed value of 0.2 grams.
Test mean - target < upper limit: Test whether the mean is less than the target by a specific amount. For example, you can test whether the mean weight of the population is at least 0.2 grams less than the target.
Upper limit: Specify the upper limit to test (for example, -0.2).
Multiply by target: Check to specify that the limit represents a proportion of the target. For example, check to specify the limit as 0.2 multiplied by the target, rather than as the fixed value of 0.2 grams.
