Labs

Each chapter has one or more labs. There are two types of labs: computer-based and hands-on.

• Computer-based labs sometimes use computer simulation to answer ``what if?'' questions, such as ``What if we add large outliers to an x-y data set: does least squares estimation still work well?'' Other computer-based labs use the power of computer simulation and computer graphics to give you a deeper understanding of statistical ideas and methods.
• Hands-on labs are intended to give you insight into the statistical ideas you are studying by having you generate data by hand and then providing activities using that data to illustrate those ideas.

You will be given class time to do the labs, but the labs, particularly the lab reports, may have to be finished outside of class. Some labs are meant to be done by a group and some are meant to be done by individuals. A lab report is required for each lab.
