This article delves into the statistical concept of confidence intervals, specifically focusing on the Student's t-distribution. It explains how William Sealy Gosset, under the pseudonym "Student," developed this distribution to correct for the uncertainty in estimating the standard deviation from small sample sizes. The piece provides practical guidance and tables for calculating 90% confidence intervals, emphasizing that a naive approach using normal distribution assumptions leads to overly narrow ranges when sample sizes are small. It also offers a method for estimating standard deviation from just two data points. AI
