The document discusses organizing data using frequency distribution tables, highlighting the importance of grouping data, calculating cumulative and relative frequencies, and understanding their advantages. It provides examples using tropical cyclone wind speeds and emphasizes creativity and accuracy in presenting a frequency distribution table for test scores. Additionally, it encourages further study on creating frequency histograms and applications of frequency distribution tables.

9. 1. How did you know which data
goes together?
2. What does the list tell us?
3. So, what can we do with the
list?

10. Make a frequency distribution table from the data.

11. Frequency Distribution
•The number
of times
something
occurred
•The way
something is
divided or
spread out

12. Frequency Distribution
• -a tabulation of grouping data
that shows the different values
of the variable.

13. Class
The classification of values or
categories
-start from the least value

14. Class Interval
Numerical width (number of
values on a certain class)

15. Cumulative Frequency
(<cf) this can be obtained by
taking the sum of the frequency
of the class and the frequencies
of the lower classes.

16. Relative Frequency
•Is the frequency divided by the
total frequency of all class
expressed as %.

17. 1. Why is it advantageous to
group data?
2. What do the data on the table
tell us?
Analysis

18. Generalization
1. How do we organize data in a
frequency distribution table?
2. What are the information found
on the frequency distribution
table?

19. Application
Consider the midyear test scores of 45 students in
Mathematics VII. Given the set of data, make a
frequency distribution table and present your output
creatively with the following twist. Use i=5.
