An introduction to major concepts of statistics (distribution, measures of central tendency, measures of variation) and how to make some common statistical graphs (histogram, box-and-whisker plot, stem-and-leaf plot). The lessons cover statistical concepts usually studied in 6th-7th grade math, but they also work well for review or as beginner lessons for anyone who needs to learn these concepts.
