Analyzing Heart Rate Data

Mrs. Hawk introduces a math lesson on displaying data distributions, focusing on dot plots. The lesson uses a heart rate example to teach data collection and visualization. Students learn to create and analyze dot plots, interpret data, and answer related questions. Additional examples and practice questions are provided to reinforce learning.

What is a statistical question?

• A question that is based on personal opinion.

• A question that has a yes or no answer.

• A question that requires data from multiple sources.

• A question that can be answered with a single number.

• To compare her heart rate with Olympic athletes.

• To find out the average heart rate of her class.

• To determine the fastest runner in her class.

• To see if her heart rate was the highest.

What is the purpose of a dot plot?

• To display data in a pie chart format.

• To compare two different datasets.

• To show the frequency of data points.

• To calculate the average of a dataset.

How did Mia decide the range for her dot plot?

• She chose numbers based on her favorite numbers.

• She started from zero and went up to 100.

• She started from the lowest heart rate and ended at the highest.

• She used random numbers to create the plot.
