Day 128: Box-Plots / Sampling Methods

Students in Math 6 used their understanding of median from Friday to begin working with Lesson 8.3: Display Data in Box Plots. Mr. Giomini introduced and modeled how to find different data points in a data set that are important when constructing a box-plot: lower extreme, quartile one, quartile two, quartile three, and upper extreme.

Math 6+ students worked with different types of sampling methods that they can use to gather data.

Students also discussed sampling bias and how they can create a surveyor's desired outcome and possibly alter the effectiveness of a sample's results.

Today's lesson objective(s):

1. Display numerical data in plots on a number line, including dot plots, histograms, and box plots.
2. Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. (7th grade) 
3. Understand that random sampling tends to produce representative samples and support valid inferences. (7th grade)
