How to approach this question
Look at the 'Average daily exercise (minutes)' column in Table 3. The mode is the value that appears most frequently in this list. Scan the list of numbers and identify which one occurs more than any other.
Full Answer
30
The mode is a measure of central tendency that represents the most common value in a dataset. To find the mode, you look at the list of values for 'Average daily exercise': 30, 12, 5, 2, 8, 14, 30, 15, 28, 45. By inspecting the list, you can see that the number 30 appears twice, while all other numbers appear only once. Therefore, 30 is the mode.
Common mistakes
