Data Analysis & Visualization Assessment

Instructions for the Assignment

• Make a Chart in Excel: Use Excel to create a CLUSTERED Bar chart AND a STACKED Bar chart. You will need to clean up the data a little bit first to make it easier to understand.
• Creating a stacked bar chart and a clustered bar chart is advisable, as it would enable you to effectively convey both the overall follower distribution and the specific comparisons between categories. This combination will provide your audience with a richer understanding of the data from multiple perspectives.
• Write a Short Story: Write one paragraph (no more than 200 words) about what you find interesting in your chart. What does it tell you about the data?

Steps to Write the Short Story

• Choose a Heading: Create a title that encapsulates the main theme of your findings. Make it engaging and relevant.
• Introduction (1-2 Sentences): Start with a statement that identifies the main point you found interesting in the chart.
• Key Details (3-4 Sentences): Reference specific datasets or numbers that you observed from your chart and describe the categories it includes.
• Analysis (2-3 Sentences): Discuss the implications of the data. Mention the relationship between follower counts and engagement rates.
• Conclusion (1-2 Sentences): Wrap up with a broader insight or what you think this might mean for brands or the influencer marketing field.

Mentor’s Step-by-Step Guidance in Approaching the Assessment

1. Understanding the Task

   • The mentor explained the importance of creating two types of charts to provide both comparative and distributional perspectives.

   • Emphasized how cleaning the dataset first ensures clarity in the visualizations.

2. Data Cleaning in Excel

   • Guided the student to remove irrelevant fields, rename headings for clarity, and format the data consistently.

   • Ensured that the dataset could be easily converted into meaningful charts.

3. Creating the Charts

   • Mentor demonstrated how to use Excel to build:
     • Clustered Bar Chart → highlighting differences between categories (e.g., influencers, platforms, engagement rates).
     • Stacked Bar Chart → showing proportions and overall distribution within categories.

   • Encouraged comparing the two visualizations to see how they provide complementary insights.

4. Writing the Short Story

   • Mentor broke down the structure for the paragraph:
     • Heading → Make it catchy and relevant.
     • Introduction → State the most interesting observation.
     • Key Details → Reference numbers and categories directly from the charts.
     • Analysis → Explain what the data suggests (e.g., higher follower counts don’t always equal higher engagement).
     • Conclusion → Provide broader implications for brands/influencer marketing.

   • Reviewed the draft to ensure it stayed under 200 words, was concise, and flowed logically.

5. Final Refinement

   • Mentor checked formatting of charts, clarity of labels, and ensured the story directly reflected insights from both charts.
   • Ensured academic tone was maintained while keeping the explanation simple and engaging.

Final Outcome & Learning Achievements

At the end of the process, the student:

• Produced two professional charts (clustered and stacked) that clearly conveyed both category comparisons and distribution insights.
• Wrote a well-structured short story (within 200 words) that highlighted the main findings, supported by data references, and concluded with broader implications.
• Demonstrated ability to clean and organize data, use Excel for visualization, and interpret findings effectively .
• Achieved learning objectives related to:
  • Data visualization and interpretation
  • Analytical thinking
