Statistics in Action Case: Modeling Sampling Variation
The normal curve is mathematical and abstract, but it shows up again and again in data and statistics. You can discover this phenomenon first-hand in a variety of places, even product packaging. This hands-on experiment introduces two important statistical concepts: the presence of differences between samples (what we call sampling variation) as well as the role of averaging in producing normal distributions. We’ll then use the normal distribution for counting the number of items in an automatically filled package.
