UNGROUPED DATA

11. 1. Make three columns. Arrange the
data in order in the first column.
2. Make a tally.
3. Count the tallies then write the
frequencies.
4. Total all the frequencies.

12. Below are the results of a survey about the favorite
colors of 15 students in a freshman class. What color is
the most favorite of the students and the least favorite
color?
Example 1:
G R Y W R
V B G Y B
Y R W R G

13. Step 1:
Make three columns. Arrange the data in order in
the first column.

18. An airline asked their passenger on a flight to rate the quality
of their service. The table below shows the ratings of 24
passengers. Make a frequency distribution table of the data
collected. How many passengers gave a rating of 3 and
below?
Example 2
Service
3 5 4 3 4 3
4 2 1 4 3 5
5 1 2 5 3 1
4 3 5 2 5 2
5-Excellent
4-Very Good
3-Good
2-Fair
1-Poor

19. Service Rating Tally Frequency
Excellent
Very good
Good
Fair
Poor
Total:
The rates of 3 and below consist of good (3), fair (2), and
poor (1). Their frequencies are 5,5, and 3, respectively.
Adding these three frequencies will result in 13, the
number of passengers who gave a rating of 3 and
below.

21. Data Sorting
Challenge
Instructions: Create a frequency distribution
table and answer the following questions:

22. "Maria conducted a survey in her
neighborhood to find out how many books
each household owns. She randomly
surveyed 15 households and recorded the
number of books they had. The results are as
follows:
5 8 5 10 3
12 7 9 6 11
4 7 14 6 10

23. 1. What is the most common number of
books owned by households in the
neighborhood?
2. What is the least common number of
books owned?
3. How many households own between 5 and
10 books (inclusive)?

24. ANSWER!
Number of Books Tally Frequency
3 I 1
4 I 1
5 I 1
6 II 2
7 II 2
8 I 1
9 I 1
10 II 2
11 I 1
12 I 1
13 I 1
14 I 1
Score: 15

25. ANSWER!
1. The most common number of books owned by
households in the neighborhood is 6,7 and 10.
2. The least common number of books owned is 3, 4, 5,
8, 9, 11, 12, 14, and 15
3. To find out how many households own between 5 and
10 books (inclusive), we need to sum up the
frequencies of the numbers between 5 and 10 in the
frequency distribution table. By adding these
frequencies together, we get 1 + 2 + 2 + 1 + 1 + 2 = 9.
So, 9 households own between 5 and 10 books
(inclusive).

26. State the steps in
constructing a frequency
distribution table for
ungrouped data.
