    Study Notes

    Diagnostic Analytics

    • Answers "Why did it happen?" by identifying causes of past events.
    • Helps organizations understand relationships between different variables.
    • Key techniques include Data Discovery, Data Mining, and Correlations.
    • Advanced methods like Regression and Time Series Analysis are often used.
    • Machine Learning Models assist in uncovering complex patterns from large datasets.

    Predictive Analytics

    • Focuses on future possibilities and outcomes, answering "What could happen?"
    • Utilizes historical data through statistical algorithms and machine learning.
    • Applications include sales forecasting, credit scoring, and predicting customer behavior.
    • Emphasizes proactive decision-making based on potential future scenarios.
    • Commonly implemented using programming languages like Python or R.

    Prescriptive Analytics

    • Recommends specific actions to achieve desired outcomes (e.g., optimizing supply chains).
    • Combines insights from Descriptive and Predictive analytics to guide decisions.

    Importance of Data Analytics

    • Reduces inefficiencies and streamlines operations across various sectors.
    • Drives revenue growth by providing actionable insights.
    • Enhances decision-making by offering data-driven recommendations.
    • Lowers operational expenses through improved processes.
    • Improves customer experiences and satisfaction.

    Data Analytics Roles

    • Data Analysts: Identify key insights from data, communicate findings, and solve organizational problems.
    • Data Scientists: Combine statistical and programming skills with industry knowledge to derive insights and drive results.
    • Business Analysts: Assess organizational performance and facilitate improvements in processes and systems.

    Data Analysis vs. Data Analytics

    • Data Analysis: Focuses on historical data to understand past events and performance.
    • Data Analytics: Aims to predict future events and trends, facilitating forward-looking strategies.

    Types of Data Analytics

    • Descriptive Analytics: Simplest form, summarizes historical data to identify trends and relationships without deeper exploration.

      • Example: Hospitals analyzing patient records to track trends such as average wait times and diagnoses.
    • Diagnostic Analytics: Analyzes past events to derive reasons for outcomes.

    • Predictive Analytics: Projects future events based on statistical and machine learning techniques.

    • Prescriptive Analytics: Provides recommendations for specific actions based on data analysis.
