Study Notes
Data Literacy
- Data literacy involves understanding, working with, and discussing data effectively.
- It's crucial for informed decision-making, critical thinking, problem-solving, and innovation.
- Data tells stories, but it's essential to critically evaluate data before drawing conclusions.
Data Pyramid
- The data pyramid consists of stages to work with data.
- Data is raw and needs processing.
- Processing data creates information.
- Information leads to knowledge of events.
- Knowledge leads to understanding the reasons behind events (wisdom).
Data Security and Privacy
- Data privacy (information privacy) is the proper handling of sensitive personal and confidential data.
- It requires meeting regulatory requirements and protecting data confidentiality.
- Data security safeguards information from unauthorized access, corruption, or theft throughout its lifecycle.
Data Acquisition
- Data acquisition is gathering suitable data for training AI models.
- Data discovery entails searching for datasets.
- Data acquisition involves gathering data, augmenting it, and generating it when necessary.
Ethical Concerns in Data Acquisition
- Bias: Avoiding preferences and partialities in data collection.
- Consent: Obtaining permission for data collection and usage.
- Transparency: Clearly explaining data usage intentions.
- Anonymity: Protecting the identities of data contributors.
- Accountability: Taking responsibility for data handling.
Types of Data
- Textual Data (Qualitative): Words and phrases used in NLP (Natural Language Processing)
- Numerical Data (Quantitative): Numbers used in statistical analysis (e.g., cricket score).
- Continuous Numerical Data: Data that can take any value within a range (e.g., height).
- Discrete Numerical Data: Data that can only take whole number values (e.g., number of students).
Data Interpretation
- Data interpretation is understanding processed data to answer critical questions.
- Quantitative data analysis focuses on numerical data, looking at quantity.
- Qualitative data analysis explores emotions, reasoning behind actions, and how participants feel.
Methods of Data Interpretation
- Quantitative: Interprets numerical data (e.g., "How many students like online classes?").
- Qualitative: Interprets data about feelings and emotions (e.g., "Why do students like online classes?").
Data Presentation
- Data is presented in various formats (tables, charts, graphs) for better understanding.
- Graphical Data Interpretation: Using visual aids like bar graphs, pie charts, and line graphs to display and interpret data.
Importance of Data Interpretation
- Informed Decision-Making: Decisions are better with insightful data.
- Identifying Trends and Patterns: Helps to understand patterns.
- Cost Reduction: Identifying costs related to specific issues and saving money.
- Meeting Needs: Understanding user needs and tailoring services.
Best Practices for Acquiring Data
- Information Quality: Ensure data accuracy, consistency, and relevance.
- Data Acquisition Methods: Utilize appropriate methods for acquiring data (e.g., web scraping).
- Ethical Considerations: Account for bias, consent, transparency, anonymity, and accountability.
