Presenting Data

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.
