Question 3: Interpreting infographics A 23-year-old male university student is given the task in their exercise physiology class to record their heart rate (in beats per minute) while completing three different activities (resting, walking, and running) each day for a month. He uses excel to create box and whisker plots (Figure 4) to compare central tendency and the spread of the data collected. In 200 - 400 words (written in complete sentences but can be presented as a paragraph or separate dot points);Explain and compare the information in Figure 4 by determining and discussing relevant values including median, maximum, minimum and interquartile range for the three activity types.What percentage of recordings at rest (Figure 4) were between 80 – 95 beats per minute?Does the student have a healthy resting heart rate (see Figure 5)?Has the data been presented effectively in Figure 4?

Question 3: Interpreting infographics

A 23-year-old male university student is given the task in their exercise physiology class to record their heart rate (in beats per minute) while completing three different activities (resting, walking, and running) each day for a month. He uses excel to create box and whisker plots (Figure 4) to compare central tendency and the spread of the data collected.

In 200 - 400 words (written in complete sentences but can be presented as a paragraph or separate dot points);

Explain and compare the information in Figure 4 by determining and discussing relevant values including median, maximum, minimum and interquartile range for the three activity types.
What percentage of recordings at rest (Figure 4) were between 80 – 95 beats per minute?
Does the student have a healthy resting heart rate (see Figure 5)?
Has the data been presented effectively in Figure 4? Please explain your answer.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
