Organization: North Carolina Standard Course of Study
Grade Band: 7th Grade
Standard Goal: The learner will understand and use graphs and data analysis.
| Histograms and Bar Graphs |
Lesson: Introduction and fine points of using bar graphs and histograms.
| | Introduction to Statistics: Mean, Median, and Mode |
Lesson: Introduces statistical measures of center.
| | Stem-and-Leaf Plots |
Lesson: Introduces students to stem-and-leaf plots and calculating the mean, median, and mode from the plots.
| 
Histogram |
Activity: View histograms for built-in or user-specified data. Experiment with how the size of the class intervals influences the appearance of the histogram. Parameters: Data sets, class sizes.
| 
Measures |
Activity: Enter data and view the mean, median, variance, and standard deviation of the data set. Parameters: Number of observations, range for observations, which statistics to view, identifiers for the data.
| 
Skew Distribution |
Activity: Change the median and standard deviation of an automatically generated normal distribution to create a skewed distribution, allowing them to observe properties like what it means for the mean, median, and mode to be different. Parameters: median, standard deviation, number of trials, class intervals.
| 
Stem and Leaf Plotter |
Activity: View stem-and-leaf plots of your own data, and then practice finding means, medians and modes. Parameters: Data
