| Question | Answer |
|---|---|
| What is data presentation? | The process of organizing data into logical, meaningful categories for interpretation. |
| What is the purpose of data presentation? | To make data intelligible, interpretable, and connected to research questions. |
| What are the three main reasons to present data properly? | To catch attention, highlight key information, and convey data concisely. |
| What are the three ways of presenting data? | Graphical, tabular, and textual. |
| What is a graph? | A pictorial representation showing variations or relationships between variables. |
| What is the purpose of graphing data? | To present changes and relationships in an attractive and convincing way. |
| What are the two components of graphical presentations? | Data components and descriptive components. |
| What are examples of data components in a graph? | Bars, slices, diagrams, and other visual elements. |
| What are examples of descriptive components in a graph? | Title, legend, labels, gridlines, footnotes, and data source. |
| What is a pie chart? | A circle divided into proportional sectors representing categories. |
| What is the maximum recommended number of slices in a pie chart? | Five slices. |
| Where should the largest slice of a pie chart begin? | At the 12 o’clock position. |
| What is a bar graph used for? | Comparing frequencies of categories quickly and clearly. |
| Why should bar graphs start at zero? | To avoid exaggerating differences between bars. |
| What is a histogram? | A bar-like graph showing the distribution of continuous data with no gaps. |
| What is a line graph used for? | Tracking changes over time and comparing trends across groups. |
| What is the maximum recommended number of lines in a line graph? | Three lines. |
| What is a scatter plot used for? | Showing correlation or its degree between two variables. |
| When should scatter plots be avoided? | When data is too dispersed, too few, too many, or overlapping. |
| What is one guideline for constructing good graphics? | Avoid distortion and unnecessary clutter so the data stands out. |
