This chapter discusses the analysis, presentation, and interpretation of data collected for a research study. It describes the processes of analyzing data by breaking it into constituent parts to address specific research questions, and presenting data by organizing it into logical categories. Analysis and presentation put the data in a proper order and form so that relationships between questions and answers can be established. As an example, one research question asked about the protein content of different types of kroepoek. A table shows the rice-shrimp variety has the highest protein content at 10.53%. Textual, tabular, and graphical methods are described for presenting data.

Interpretation of
Data

2. All specific questions in
Chapter 1 under
statement of the
problem may be
answered in this chapter
supported with tables.

3. Analysis
It is the process of breaking up the
whole study into its constituent
parts of categories according to the
specific questions under the
statement of the problem. This is to
bring out into focus the essential
features of the study. Analysis
usually precedes presentation.

4. Presentation of Data
It is the process of organizing
data into
logical, sequential, and
meaningful categories and
classifications to make them
amenable to study and
interpretation.

5. Analysis and presentation put
data into proper order and in
categories reducing them into
forms that are intelligible and
interpretable so that the
relationships between the
research specific questions and
their intended answers can be
established.

6. Research Problem # 1
( under statement of the problem )
1. What is the protein
content of Kroepoek from
Rice-Shrimp, Rice-
Squid, Rice-Oyster, and
Rice-Crab?

7. Table 1. Protein Content of Kroepoek from Rice-
Shrimp, Rice-Squid, Rice-Oyster, and Rice-Crab
ProteinContent
Kroepoek Percent Rank
Rice-Shrimp 10.53 1
Rice-Squid 9.91 2
Rice-Oyster 8.05 3
Rice-Crab 8.00 4

8. The result showed that rice-shrimp
kroepoek has the highest protein
content, 10.53 %; second, rice-oyster
kroepoek, 9.91 %; third, rice-crab
kroepoek, 8.05 %; and fourth, rice-
squid, 8.00%. Table 1 presents the
protein content of Rice-
Shrimp, Rice-Squid, Rice-
Oyster, and Rice-Crab

9. Three Ways of Presenting Data
1. Textual Presentation of Data
It uses statements with
numerals or numbers to describe
data. The main aims of textual
presentations are to focus attention
to some important data and to
supplement tabular presentation.

10. 2.Tabular Presentation
A statistical table or simply table is
defined as systematic arrangement of
related data in which classes of
numerical facts or data are given each
a row and their sub classes are given
each a column in order to present the
relationships of the sets or numerical
facts or data in a definite ,compact
and understandable forms.

11. 3.Graphical Presentation of
Data.
A graph is a chart representing the
quantitative variations or changes of
a variable itself , or quantitative
changes of a variable in comparison
with those of another variable or
variables in pictorial or
diagrammatic form.

12. Limitations of graphs
1. Graphs do not show as much
information at a time as do tables.
2. Graphs do not show data as
accurately as the tables do.
3. Charts require more skill, more
time, and more expense to prepare
than tables.

13. Types of graphs or charts
1. Bar graphs
2. Linear graphs
3. Hundred percent graphs or charts
4. Pictographs
5. Statistical maps
6. Ratio charts
