**Data Input for Sample Size Estimation** is a table of 4 columns

- Each row contains data from a separate study
- Col 1 = probability of Type I error (α)
- Col 2 = power (1-β)
- Col 3 = mean of paired differences
- Col 4 = Standard Deviation of paired differences

**Data Input for Power Estimation** is a table of 4 columns

- Each row contains data from a separate study
- Col 1 = probability of Type I error (α)
- Col 2 = sample size (Pairs) used
- Col 3 = mean of Paired Differences observed
- Col 4 = Standard Deviation of paired differences

**Data Input for Confidence Interval Estimation** is a table of 3 columns

- Each row contains data from a separate study
- Col 1 = percent confidence (usually 95)
- Col 2 = sample size used (pairs)
- Col 3 = standard deviation of paired differences observed

**Data Input for Pilot Study** is for a single plan, a single column with 4 rows

- Row 1 : Percent Confidence required, usually 95 or 99
- Row 2 : Standard Deviation of Paired Mean
- Row 3 : Sample Size Interval
- Row 4 : Maximum sample size
