Study Notes
Data Science Overview
- Multidisciplinary field focused on extracting actionable insights from large datasets.
- Combines techniques from computer science, statistics, machine learning, and predictive analytics.
- Aims to solve problems that have not yet been identified.
- Methodologies involve both problem-solving and designing new data modeling processes.
Data Analysis Definition
- Examines and processes raw data to convert it into usable information.
- Essential for organizations to make informed decisions based on thorough analysis.
- Data analysts focus on statistical analysis of existing datasets to derive insights.
- The goal is to address known unknowns and produce immediate actionable results.
Traditional vs. Modern Data Analysis Approaches
- Traditional analysis is often isolated, dealing primarily with structured data and employing descriptive methods.
- Modern analysis emphasizes predictive capabilities to reveal performance patterns and trends.
Excel Basics
- Excel is structured with various essential parts:
- Quick Access Toolbar: Stores crucial tools for easy access.
- Ribbon: Expanded menu for commands.
- Formula Bar: Displays formulas and calculations.
- Spreadsheet Grid: Area for data and charts.
- Status Bar: Displays current status and notifications of Excel.
Navigating Excel
- The Title Bar indicates the current workbook and program name.
- Tell Me feature allows quick access to features and assistance.
- Clipboard functionality enables the storage of multiple copied items for easy pasting.
