Description of the formula

Variables Definitions

  1. Confidence Interval (CI): This represents the confidence level expressed as a decimal value. For example, 0.95 corresponds to a 95% confidence interval.
  2. Number of Participants: The total number of individuals or data points in the sample or study.
  3. Upper CI Limit: The upper limit of the confidence interval.
  4. Lower CI Limit: The lower limit of the confidence interval.
  5. Standard Deviation (SD): The calculated standard deviation based on the provided confidence interval information.

Conversion Formula
