1. Graph for Data PresentationComputer science 2nd Stage College of PharmacyHussein Alsheakh, Ph.D.1
2. Use the right type of graphicCharts and graphsBar chart: comparisons, categories of dataHistogram: represents relative frequency of continuous dataLine graph: display trends over time, continuous data (ex. cases per month)Pie chart: show percentages or proportional share2
3. Bar chartComparing the categories of data What should be add-Title and data labels.- The source of the data
4. Bar ChartSource: Quarterly Country Summaries, 2008
5. Stacked bar chart% Children <5 with Fever who Took Specific Antimalarial, 2007-2008To compare multiple values when the values on the chart represent durations or portions of an incomplete whole.
6. Histogram- Presents quantitative variables
7. Bar Chart v. Histogram7Data fabricated for illustration- Columns can be arranged
8. Bar Chart v. Histogram (cont.)8Data fabricated for illustration- Order of the columns is very specific
9. Population Pyramid: Country Z, 2008- Two histograms presentedside by side- Useful for presenting descriptive data
10. Line graph*Includes doctors and nurses.Number of Clinicians* Working in Each Clinic During Years 1-4, Country YTo display trends over time and is particularly useful when there are many datapoints (ex 4).
11. Caution: Line GraphNumber of Clinicians* Working in Each Clinic During Years 1-4, Country Y*Includes doctors and nurses.- What is wrong with this line graph?
12. Pie chartDisplays the contribution of each value to a totalWhat should be added to this chart to provide the reader with more information? - The color scheme, which is currently too bright- The title should be more specific and indicate whether these are numbers or percentages.
