Using Bootstrapping to Obtain Confidence Intervals for Medians

In a review of employee records, management is interested in the previous work experience of employees. Work experience is right skewed, which makes the mean a less desirable estimate of the "typical" previous work experience among employees than the median. However, without bootstrapping, confidence intervals for the median are not generally available in statistical procedures in the product.

This information is collected in Employee data.sav. See the topic Sample Files for more information. Use Bootstrapping to obtain confidence intervals for the median.

Note: this example uses the Explore procedure, and requires the Statistics Base option.
