Experiment: Searching the Forest

You should have a bag that another group has “populated” with colored tiles. Your job is to predict the number of each color in the bag. But you cannot dump all the tiles out and count them! You are like a scientist exploring a big, deep forest. You can only look at a little bit of the forest at a time.

You are only allowed to take samples of the tiles. Each sample must have exactly ten tiles in it. After each sample, return the tiles to the bag and shake it up before you take the next sample.

1. Draw a picture of the experiment. Label the variables in your picture.
1. What are the two main variables in your experiment?
2. Tell whether each of the main variables is categorical or numerical.
