2) What term best describes the mode of this data set?

Bimodal

Unimodal

Trimodal

No mode

Bimodal means the data set has two different modes. For example, if the values 2 and 5 appear most frequently, the data is bimodal. Check the frequencies of each number to determine if there are two distinct modes.

Explanation

Submit

3) What does having two modes mean in this context?

The player always scores 10 or 12 points

The player most often scores either 10 or 12 points

The average is 11

The total points are double the average

Having two modes means the most frequent scores are 10 and 12. This indicates that in a set of scores, 10 and 12 appear more often than other numbers, highlighting a bimodal distribution.

Explanation

Having two modes means the most frequent scores are 10 and 12. This indicates that in a set of scores, 10 and 12 appear more often than other numbers, highlighting a bimodal distribution.

4) If one of the 10-point games changes to 14 points (correction), what is now the mode?

The mode is the most frequent value. With the change, 14 occurs most often, making it the mode. Before, 10 was the most frequent, but now with one 10 turned to 14, it surpasses 10.

Explanation

The mode is the most frequent value. With the change, 14 occurs most often, making it the mode. Before, 10 was the most frequent, but now with one 10 turned to 14, it surpasses 10.

Submit

5) Which value is the mode?

The mode is the number that appears most frequently in a data set. In this case, 9 is the most common value among the options provided.

Explanation

The mode is the number that appears most frequently in a data set. In this case, 9 is the most common value among the options provided.

Submit

6) What does the mode tell you about the plants?

The most common height after 4 weeks is 9 inches

The tallest plant is 10 inches

The average height is 8 inches

The range is 3 inches

The mode represents the height that appears most frequently. If 9 inches is reported as the mode, it means that this height occurs more often than any other, confirming it as the most common height.

Explanation

The mode represents the height that appears most frequently. If 9 inches is reported as the mode, it means that this height occurs more often than any other, confirming it as the most common height.

Submit

7) If two more plants at 7 inches are added, what happens to the mode?

There are two modes: 7 and 9

There is no mode

It becomes 7 only

It becomes 8

Adding two more plants at 7 inches increases the frequency of 7 inches to three. The data set now has modes at both 7 and 9 inches since both occur more than once, resulting in two modes.

Explanation

Adding two more plants at 7 inches increases the frequency of 7 inches to three. The data set now has modes at both 7 and 9 inches since both occur more than once, resulting in two modes.

Submit

8) What is the mode of the number of pets?

The mode is the number that appears most frequently. Here, 2 is the most common number of pets among the data provided.

Explanation

The mode is the number that appears most frequently. Here, 2 is the most common number of pets among the data provided.

Submit

9) In this context, what does the mode best describe?

The most common number of pets students own

The average number of pets

The largest number of pets

The median number of pets

The mode refers to the value that appears most frequently in a data set. In this case, it describes the most common number of pets students own, making option A the correct choice.

Explanation

The mode refers to the value that appears most frequently in a data set. In this case, it describes the most common number of pets students own, making option A the correct choice.

Submit

10) If the student with 4 pets moves away and is removed from the data, how does the mode change?

It becomes 1

It becomes 3

It stays 2

There is no mode

The mode is the value that appears most frequently. If the student with 4 pets is removed, the data's most common value remains 2, as it still appears more than any other number.

Explanation

The mode is the value that appears most frequently. If the student with 4 pets is removed, the data's most common value remains 2, as it still appears more than any other number.

Submit

11) What is the mode of the temperatures?

The mode is the number that appears most frequently. In this case, 75 is the most common temperature recorded, making it the mode.

Explanation

The mode is the number that appears most frequently. In this case, 75 is the most common temperature recorded, making it the mode.

Submit

12) Which statement is most accurate about the weather?

It was always 75 degrees

72 and 75 were equally common

There is no most common temperature

75 degrees occurred more frequently than any other temperature

Statistical data shows that 75 degrees is reported as the most frequent temperature, meaning it occurs more times than any other temperature, confirming option D as correct.

Explanation

Statistical data shows that 75 degrees is reported as the most frequent temperature, meaning it occurs more times than any other temperature, confirming option D as correct.

Submit

13) If three more days at 72 degrees are added, what happens to the mode?

There are now two modes: 72 and 75

It changes to 72 only

It remains 75 only

There is no mode

Adding three more days at 72 degrees increases its frequency, making it a mode along with 75. The mode is the most frequently occurring value, so now both 72 and 75 qualify as modes.

Explanation

Adding three more days at 72 degrees increases its frequency, making it a mode along with 75. The mode is the most frequently occurring value, so now both 72 and 75 qualify as modes.

Submit

14) What is the mode of the data set?

The mode is the number that appears most frequently. If '5' appears more often than any other number, it is the mode.

Explanation

The mode is the number that appears most frequently. If '5' appears more often than any other number, it is the mode.

Submit

15) What does the mode represent in this context?

The average number of books read by each student

The number that appears exactly twice

The number of books most students read

The total number of books read by the class

The mode is the value that appears most frequently in a data set. In this case, it indicates the number of books that the majority of students read.

16) If another student who read 5 books is added, how does the mode change?

There is no mode

It stays the same

It becomes 4

It becomes 3

The mode is the number that appears most frequently. If a student who read 5 books is added, the most common value remains unchanged. Thus, the mode stays the same.

Explanation

The mode is the number that appears most frequently. If a student who read 5 books is added, the most common value remains unchanged. Thus, the mode stays the same.

17) Which statement is true about the data set's mode?

There are two modes: 4 and 5

There are three modes: 2, 3, and 4

There is one mode: 5

The data set has no mode

The mode is the number that appears most frequently. Adding a student who read 5 books increases the frequency of 5. If others read fewer, 5 becomes the only mode, changing the mode from possibly multiple to just one: 5.

Explanation

Submit

18) If the teacher wants to describe a typical number of books read in this class, which statistic best matches that idea here?

The range, because it shows variability

The minimum, because it’s the smallest

The median, because it’s central

The mode, because it shows the most common number

The mode is the most frequently occurring number in a data set, making it ideal for identifying typical values. In this case, it indicates the most common number of books read, which best represents the class's reading behavior.

Explanation

Submit

19) What is the best interpretation of the mode in the data set of pages read each night?
