Why Lesson Planet?
Simulate a random sampling of data by tearing 20 sheets of paper into slips and place a number on 10 and a letter on 10. They place the slips in two separate containers and randomly draw a number and a letter. They record their selections and count a population of sunflower plants from a grid that corresponds to the number-letter combination. They repeat this process until they've counted 10 different grid segments. This is their random sample.
