In the context of organizing experimental results, what is the PRIMARY purpose of a data table?
- To showcase visual evidence, such as photographs of the experimental setup.
- To organize and display large amounts of data in a readable format. (correct)

How does incorporating related literature enhance the interpretation of experimental data?
How does incorporating related literature enhance the interpretation of experimental data?
- It provides visual evidence, like photographs, to support claims.
- It is not important, interpretation of the data is based on the researcher's understanding.
- It offers different perspectives, potentially contradicting the experimental findings.
- It adds credibility and supports claims by providing context and comparison to existing knowledge. (correct)

Study Notes
- Data is organized after it is observed and measured from an experiment using graphs, pictures, tables, and diagrams.
- Organized data is described or interpreted afterwards.
- Specific literature is used when interpretations are made so meaning can be extracted from organized data.
Tables
- Large amounts of data are organized into an easily readable format with tables or data tables.
- Tables can be used to present just enough data from an experiment.
Graphs
- Relationships between variables are shown in graphs such as bar and line graphs.
- Bar and line graphs present how effectively the independent variable affects the dependent variable.
- The correlation between fertilizer concentration and plant height is displayed in the bar graph example.
- The the relationship between pesticide exposure time and insect mortality rate in percentage is displayed in the example line graph.
- Line graphs are better suited to time as a variable, even though bar and line graphs may appear to serve the same purpose.
Pictures
- Visual proof of data is shown in pictures or photographs.
- Examples of studies that would need images are antibacterial activity (zone of exhibition), use of fertilizer (photos of plants), and study of tiny material surfaces.
Interpreting Data
- Data interpretation involves describing or elucidating the data's meaning once it has been structured and presented.
- Basic guidelines to interpret the data:
- Discuss what the data mean, include supporting literature, and cite the literature's author
- Clearly explain the relationships between variables in the graph, as well as the relationships between the results and the hypothesis.
- The example shows zones of inhibition exhibited by Calamansi peel oil against Staphylococcus aureus.
- The picture was given the proper meaning or interpretation with the use of existing scientific information or literature review in the examples.
- The relationship of variables (concentration of essential oil and zone of inhibition against the bacterium) was explained in the graph.
- Literature review was also used for the meaning or interpretation of data which was expressed in means.
