7.3b- Math Coach Corner
Does a higher average automatically mean one group is greater? In this Math Coach Corner connected to Lesson 8.3: Comparing Populations, we use the mean and MAD to decide if a difference in attendance is truly meaningful. The student council compares a Movie Night and a Talent Show — but does the difference really matter? Learn how to evaluate claims using statistical reasoning aligned to 7.SP.B.3.

7.SP.B.3
Download the PDF worksheet that goes with this review to practice along with the video.
Let’s review how statisticians use random samples to compare populations! In this section review, you’ll practice analyzing dot plots and box-and-whisker plots using measures of center (median) and variation (IQR). Pause the video, solve the problems on your own, and then watch as each solution is explained step by step. This review is a great way to prepare for quizzes, tests, and unit exams.

7.4b - Math Coach Corner
Can you solve this statistics challenge?
In this Math Coach Corner, one of my students claims that Jake’s farm produces more corn because its median is higher on a double box-and-whisker plot.
But is that really enough evidence?
Pause the video, analyze the random sample data, and see if you agree before I walk through the answer using median and IQR.
