One year so and as the highest frequencies. B- The distribution is skewed to the left. Explain. And what we're gonna do in this video is do exactly that, in fact, this one we're gonna describe and in a future video we're going to compare distributions. please refer to the resources on our message board including: guided notes, unit vocabulary sheet, desmos calculator and more to help you work through this problem. This calculator allows you to create a special table where each data value is split into a stem (the first digit or digits) and a leaf (usually the last digit). Describe the shape of the distribution. A stem and leaf plot is used to organize data as they are collected. For stem-and-leaf plots, we group data together by the first . % Progress The leaves should be arranged in ascending order on each stem. 13.2 - Stem-and-Leaf Plots; 13.3 - Order Statistics and Sample Percentiles; 13.4 - Box Plots; 13.5 - Shapes of distributions; Lesson 14 .
