In Sixth Grade
-
In sixth grade, students represented and interpreted data numerically using dot plots, stem-and-leaf plots, histograms, and box plots. Box plots and histograms were graphs new to sixth grade as well as being introduced to measures of center and measures of spread.
In Seventh Grade
-
Students in seventh grade will solve problems related to bar graphs, dot plots, and circle graphs. Circle graphs are new to seventh grade. Comparisons of dot plots and box plots using shapes, center, and spreads will be representing numerically. Students will also take random samples from two populations and use the data to make comparisons of two populations by making inferences.
In Eighth Grade
-
In eighth grade, students will use bivariate data sets to compare and contrast linear and non-linear relationships. Students are introduced to trend lines and mean absolute deviation.
