Learning Activities

Description 

Introduction to the Importance of Data Filtering and Its Application in Tableau Desktop, and Practical Application of Filtering Techniques to Refine and Specify Data Analysis.

 

LA1: Contextualization (10 min)

The teacher introduces the purpose of the task:

  • Introduction to the topic of data filtering and its significance for detailed data analysis.
  • Explanation of why data filtering is crucial for extracting relevant information from large datasets and conducting precise analyses.

LA2: Working Phase (30 min)

  • Students filter their results in the program:
    • Students open their datasets in Tableau Desktop and practice applying various filtering techniques.
    • Tasks include filtering data based on specific criteria, creating filter actions, and applying range filters.
    • Students are expected to apply different filters, observe and document their impact on data visualization.
    • Analysis of the filtered data and comparison of results with the original dataset to illustrate the significance and benefits of filtering.
  • Support from the instructor:
  • The instructor is available for questions and provides individual support.
  • Tips and guidance on efficiently applying filtering techniques in Tableau Desktop.

LA5: Outlook (5-30 min)

Discussion on what can be done with the datasets:

  • Discussion of the opportunities that data filtering opens up, such as identifying specific trends, focusing on relevant data points, and creating detailed reports.
  • Discussion on advanced analyses made possible by filtering and how these can be applied in real-world scenarios.
  • Reflection on what has been learned and how students can apply filtering techniques in future projects.
