SUMMARY
To calculate the 95% confidence interval for the median of a skewed distribution, bootstrapping is the recommended method. While traditional methods apply to normal distributions using the formula 1.96 times the standard error of the mean, skewed distributions require a different approach. Tools such as R provide built-in support for bootstrapping, and users can also explore Excel for potential solutions, although documentation should be consulted for specifics.
