Students should understand the importance of proper random sampling, since it's unbiased. Since the whole point of statistics is to say something about an entire group, we need to choose a sample that represents the whole group as closely as possible.
Students should also be aware of the fact that random samples can, and often do, exhibit patterns. For instance, it's okay to have a random sample of 10 red flowers from a batch of 100 multicolored ones. A random sample is random because of howit's collected, not because of what is collected.
The most important things that students must understand are what a population is, what a random sample is, how to take random samples, and how to properly infer data from samples.
Did you know that it's statistically proven that practice makes perfect? Well, maybe not. But the best way to help students get comfortable with identifying these main ideas in statistics is through practice. Definitions are good and fine, but students have to practice to really improve their understanding, whether it's on a big screen in the classroom, at everyone's computer, or simply as a homework assignment.
