Confidence Intervals for Textile Property Estimation
topic
Confidence intervals for textile property means, standard deviations, and proportions quantify the precision of sample-based population estimates using t-distribution for means with unknown variance, chi-squared distribution for variance, and Wilson score intervals for proportions, providing interval estimates that express both the best estimate and the uncertainty range at specified confidence levels.
Role
Supplements point estimates of textile material properties with the interval information needed to assess whether sample sizes are adequate for the precision required, make statistically valid claims about population performance characteristics, and communicate the reliability of material specification estimates to customers and regulatory authorities.
