Example Questions

Example Question #1 : Mode

On the last day of school,Adam asked each of his classmates how many days of school they missed for the entire school year.  He created a stem-and-leaf plot with the information.

0 | 0 0 2 4 5 6 8

1 | 0 0 1 2

2 | 3

4 | 7

What is the mode(s) of the stem-and-leaf plot?

Possible Answers:

\dpi{100} 0\ and\ 10

\dpi{100} 47

\dpi{100} 2

\dpi{100} 0

Correct answer:

\dpi{100} 0\ and\ 10

Explanation:

The mode of a set of data is the value that occurs the most frequently. 

Here, 0 occurs twice on the first line, and twice on the second line.  These are different values since the left side of the vertical line represents the ten's place.  So on the first line, the "0" represents 0, and on the second line the "0" represents 10.  So 0 occurs twice, and ten occurs twice.

It is possible to have more than one mode.  If multiple values occur more than once, occur the same number of times as each other, and occur more than any other values, then they are both modes.
