Pick up a warm up from the front!

In this Math III warm-up from April 18, 2013, students will analyze the heights of the twenty highest dams, ranging from 225 to 335 meters. The task involves selecting appropriate class intervals, defining class limits, identifying class marks, and constructing a frequency distribution table. Additionally, students will be instructed to create a histogram to visually represent the data. Essential vocabulary for an upcoming quiz will also be reviewed, which includes terms like simple random sample and explanatory variable.
