Explanation Javascript Program R Codes Sample Size Tables
Data Input 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
