Big Ideas: Data graphed on a dot plot or histogram can be analyzed to determine the distribution characteristics of the data set. A data set that is single-peaked, symmetric, and contains no outliers may be appropriately modeled by an approximately normal distribution curve. In earlier lessons, students are introduced to histograms, dot-plots, and specific terminology to describe the characteristics of sample distributions. This lesson builds on prior knowledge to create an understanding of the properties of normal distribution. Students are encouraged to consider factors that may affect the shape of a one-variable distribution set. This in-depth thinking and exploration leads students to an understanding of what type of situations can be modeled by a normal distribution curve. Vocabulary: distribution, normal distribution, distribution curve Special Materials: Graph Paper Ruler
