Presenting Data
What is Data Presentation?
-
Data presentation is the process of visually communicating data and information for analysis and interpretation.
-
It involves representing data in a way that can be easily understood and shared.
Types of Data Presentation
-
Graphs and Charts: Graphs and charts are common tools used for data presentation. These include pie charts, bar graphs, line graphs, and scatter plots.
-
Tables and Matrices: Tables lay out information in rows and columns. Matrices are similar, but all columns and rows hold the same information types.
-
Infographics: These are visual representations of data that blend images, charts, and text. They are efficient tools for presenting complex information quickly and clearly.
-
Maps: Geographical data can be presented in various map formats, including heat maps, dot distribution maps, or choropleth maps.
Microsoft Excel
-
Excel’s data presentation features simplify the process of creating different types of charts and graphs from tabular data.
-
Chart wizard tool: Microsoft Excel’s chart wizard tool can automatically create charts based on selected data.
-
Chart types: Excel offers a variety of chart types, including column, line, pie, bar, area, and scatter.
Work with Data in MS Excel
-
Cell: A box in the grid of an Excel worksheet. Cells hold individual pieces of data.
-
Row and Column: Rows are the horizontal spaces in the grid and are numbered, while columns are vertical and designated by letters.
-
Create a chart: Select the range of cells that contains the data to graph, then choose a chart type from the Insert menu.
-
Splitting and Combining Columns: Data in a single column can be split into multiple columns using the Text to Columns feature. Multiple columns can be combined into one using the CONCATENATE function or ampersand (&).
Effective Data Presentation
-
Simplicity: An effective data presentation is simple and avoids unnecessary clutter and details.
-
Consistency: Ensuring that similar elements are represented in the same way each time helps viewers understand the visualisation more easily.
-
Colour: Colour can be used to draw attention to certain regions, depict different data categories, or represent different ranges of values.
-
Labels: All charts, graphs, and maps should have clear, easy-to-read labels that include the title, axes or legend labels, and units of measurement.
-
Accuracy: The data represented must be correct and the visualisation should accurately reflect this data.
