About This Quiz
Interpreting Mode From Graphical Displays - Quiz

Ready to take your data analysis to the next level? This quiz is all about the mode—the most frequently occurring value in a data set—and how to spot it in graphical displays! From dot plots to stem-and-leaf plots, you’ll explore how the mode shows up in different contexts.

2)
We’ll put your name on your report, certificate, and leaderboard.
2) Which statement best explains the mode in this context?

Explanation

The mode represents the value that appears most frequently in the data set, which is 4. So, the correct explanation is that more students read 4 books than any other number.

Submit
3) If one more student who read 4 books is added to the data, how does the mode change?

Explanation

Since 4 is already the mode and adding one more student who read 4 books increases the frequency of 4, the mode will stay the same.

Submit
4) If all students who read 6 books are removed, what is the mode?

Explanation

If the students who read 6 books are removed, the most frequent value left in the data set would be 4, which remains the mode.

Submit
5) If one additional dot is added at 8, what happens to the mode?

Explanation

Adding a dot at 8 does not make it the most frequent number, as 4 is still the mode. The distribution would become bimodal at 4 and 8 because both numbers would have the same frequency.

Submit
6) If the dot at 8 is moved to 4, which statement becomes true?

Explanation

If the dot at 8 is moved to 4, it increases the frequency of 4, making it even more frequent than before, so the mode at 4 becomes even more frequent.

Submit
7) Which interval contains the mode (use non-overlapping intervals)?

Explanation

The mode is 4, and the interval that contains 4 is 3–5.

Submit
8) A student says the mode is 6 because it is a larger number than 4. Why is this incorrect?

Explanation

The mode is determined by the frequency, not by the size of the number. Since 4 occurs most frequently in the data set, the mode is 4, not 6, regardless of the size of the numbers.

Submit
9) What are the modes of the data set?

Explanation

The stem-and-leaf plot shows that 32, 41, and 50 appear most frequently in the data, so the modes are 32, 41, and 50.

Submit
10) Which values occur most frequently?

Explanation

The most frequent values in the stem-and-leaf plot are 32, 41, and 50.

Submit
11) If one more 32 is added, what is the new mode?

Explanation

Adding one more 32 increases the frequency of 32, making it the new mode.

Submit
12) What does the mode represent in this context?

Explanation

The mode represents the most common value in the data set, which is the most frequent number of minutes students spent on homework.

Submit
13) If the 49 is changed to 39, how does the mode change?

Explanation

Changing the 49 to 39 does not affect the mode because 41 and 50 are still the most frequent values.

Submit
14) Which statement is true about the stem-and-leaf plot?

Explanation

There are three modes: 32, 41, and 50, as they appear most frequently in the stem-and-leaf plot.

Submit
15) What is the mode number of goals?

Explanation

The mode is the most frequently occurring value in the data set. In this case, 2 is the most common number of goals scored.

Submit
16) What does the mode tell you about the team’s typical performance?

Explanation

The mode indicates that the team most frequently scored 2 goals in a game.

Submit
17) If two games with 3 goals are added, how does the mode change?

Explanation

Adding two games with 3 goals would make 3 the most frequent value, so the mode changes to 3.

Submit
18) If every game’s goals are increased by 1, what happens to the mode?

Explanation

If every goal count is increased by 1, the mode would also increase by 1.

Submit
19) If the distribution becomes bimodal, which could be true?

Explanation

If the distribution becomes bimodal, there would be equal highest frequencies at 2 and 3 goals.

Submit
20) Which statement about mode is always true for these displays?

Explanation

The mode is always the value or category that appears most frequently in the data.
