Lesson 10 Qualitative and quantitative data
Understanding Decision Making Through Data
The Importance of Data in Decision Making
- Data is crucial for effective decision-making, as it helps answer various types of questions.
- Two primary types of data discussed are quantitative and qualitative, each serving different purposes.
Quantitative vs. Qualitative Data
- Quantitative Data: Focuses on numerical facts, answering "what," "how many," and "how often" questions (e.g., number of commuters using the train).
- Qualitative Data: Describes subjective qualities that cannot be measured numerically, helping to answer "why" questions (e.g., preferences for a celebrity or snack).
Visualizing and Contextualizing Data
- Quantitative data can be represented visually through charts or graphs, providing clear insights into trends.
- Qualitative data adds context to these numbers, enhancing understanding of underlying reasons behind the data.
Application in Business Decisions
- Customer reviews serve as an example where both quantitative and qualitative data are utilized to inform business decisions.
- A local ice cream shop uses online reviews to gauge customer satisfaction and identify areas for improvement.
Analyzing Customer Feedback
- The ice cream shop owner starts with measurable questions about negative reviews to gather quantitative data (e.g., average rating).
- Identifying patterns in negative feedback reveals common frustrations among customers, leading to qualitative inquiries about their experiences.
Implementing Changes Based on Insights
- By recognizing that customers are frustrated due to popular flavors running out, the shop can adjust its inventory accordingly.
- Combining both quantitative and qualitative insights allows the owner to make informed changes that enhance customer satisfaction.
