EMS/ST 519: Investigations w/ Real Data by Gemma Mojica https://padlet.com/gmmojica/ojvk6nz55fk1 What have you learned about engaging in investigations with real data? en-us 2019-02-13 13:09:00 UTC 2019-02-13 21:41:16 UTC hello@padlet.com Giving purpose to an investigation https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060486 A statistical investigation's meaning can be deepened if students know that their investigation will create something or be beneficial to others.]]> 2019-02-13 21:37:58 UTC https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060486 Investigations https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060577 Cleaning the data is a critical step.]]> 2019-02-13 21:38:15 UTC https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060577 https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060610 Use  real data (that might need clean up).
Pose questions of interest (not restricted to the classroom).
Look beyond the data.

Empty values in the data, as well as improbable ones, hindered the ability for reasonable conclusions to be reached. However, messy data is what exists in the real world, so students need to be exposed to it as soon as possible.]]> 2019-02-13 21:38:37 UTC https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060707 https://padlet.com/gmmojica/ojvk6nz55fk1/wish/331060830 -students don't typically go through the full investigative cycle in class - but they should in order to really understand the utility of statistics
-investigations should use real data
-students should be part of the posing questions
