Statistical Analysis of Heart Rates

The video tutorial covers module six lesson two, focusing on displaying data distributions using dot plots. Mia, a sixth grader, collects heart rate data from her classmates to investigate a statistical question. She creates a dot plot to visualize the data, analyzing it to find the lowest, highest, and most common heart rates. The tutorial also explores additional statistical questions and matches them with appropriate dot plots. Key concepts include understanding dot plots, data collection, and analysis.

What statistical question was Mia interested in investigating?

• How many students are in her class?

• How many textbooks do students have in their desks?

• What are the heart rates of the students in her sixth grade class?

• What is the average height of students in her class?

What is the range of numbers Mia used on her number line for the dot plot?

• 70 to 100

• 75 to 95

• 78 to 92

• 80 to 90
