Chapter 4Analysis, Presentati on, And Interpretation of Data
All specific questions in Chapter 1 under statement of the problem may be answered in this chapter supported with tables.
Analysis It is the process of breaking up thewhole study into its constituentparts of categories according to thespecific questions under thestatement of the problem. This is tobring out into focus the essentialfeatures of the study. Analysisusually precedes presentation.
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.
Analysis and presentation putdata into proper order and incategories reducing them intoforms that are intelligible andinterpretable so that therelationships between theresearch specific questions andtheir intended answers can beestablished.
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?
Table 1. Protein Content of Kroepoek from Rice-Shrimp, Rice-Squid, Rice-Oyster, and Rice-Crab ProteinContent Kroepoek Percent RankRice-Shrimp 10.53 1 Rice-Squid 9.91 2 Rice-Oyster 8.05 3 Rice-Crab 8.00 4
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
Three Ways of Presenting Data1. Textual Presentation of Data It uses statements withnumerals or numbers to describedata. The main aims of textualpresentations are to focus attentionto some important data and tosupplement tabular presentation.
2.Tabular PresentationA 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.
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.
Limitations of graphs1. 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.
Types of graphs or charts1. Bar graphs2. Linear graphs3. Hundred percent graphs or charts4. Pictographs5. Statistical maps6. Ratio charts
