Random Sampling

Last night, students read section 5-1 on population growth. Before scientists can measure the growth of a population over an extended period of time, they need to establish a baseline. This can be done by random sampling. Today students did a dry lab to practice random sampling.

They used data (below) on a population of sunflowers.

Homework: read sections 5.2 and 5.3. We will be doing a lab where we examine human population data, not having a lecture on these sections. We will have time at the beginning of class if you have questions on anything in the readings.

If you are able to, please bring a computer to class.
