Random sampling activity

This activity is part of the full Invasive Species & Biodiversity Data Investigation curriculum found here - http://vitalsignsme.org/invasive-species-biodiversity-data-investigation...

Students will model the experience of random versus non-random sampling to determine the total number of M&M’s in their M&M populations. First, students will choose where they want to sample, introducing bias into their sampling, and then they will try a random sampling technique. They will compile class data and compare their results to determine which sampling method is more accurate.
