# Stats lab (optional)

The 1 credit stats lab is available for students who might move on to a 4-year college or university on a semester system to have enough credits to transfer. It is also available to students who want to have additional, structured activities to enhance their understanding of the concepts covered in the lecture class.

No additional concepts will be covered. Hands-on activities will be used reinforce the material. Spreadsheets will be used in each lab.

There will be 9 labs throughout the term. Each lab is worth 10 points. Your final grade for MTH298 with be the average of your lab grades.

Lab meets in Pendleton, Hermiston, and online every Friday at 10AM. Video conferencing links will be sent out each week.
