proc-ttest-mean-comparisons

What problem does it solve?

This Skill solves the problem of comparing means of continuous variables between two groups, against a known value, or across paired measurements, especially when the variable is approximately normally distributed.

Core Features & Use Cases

• Mean Comparison: Conduct one-sample, two-sample, and paired t-tests.
• Normal Distribution Check: Assesses the normality of the continuous variable before conducting t-tests.
• Confidence Intervals & P-values: Provides confidence intervals and p-values for mean comparisons.
• Use Case: For a study comparing the mean systolic blood pressure of two groups, this Skill can be used to determine if there is a statistically significant difference.

Quick Start

Run the t-test to compare the mean systolic blood pressure between the two treatment groups using the 'ttest-systolic_bp' script.
