进行了模拟，以评估技术方差对测量响应时间的Web实验的统计功效的影响。模拟结果表明，技术方差降低了统计功效和效应量估计的准确性，其幅度可以忽略不计。因此，这一发现表明，研究人员的先入之见，关于不适合的网络实验进行研究，使用响应时间作为一个依赖的措施是误导。
A simulation was conducted to assess the effect of technical variance on the statistical power of web experiments measuring response times. The results of the simulation showed that technical variance reduced the statistical power and the accuracy of the effect size estimate by a negligible magnitude. This finding therefore suggests that researchers' preconceptions concerning the unsuitability of web experiments for conducting research using response time as a dependent measure are misguided.
