Study Notes
Data Analytics Overview
- Defined as the scientific process of transforming data into actionable insights for improved decision-making.
- Involves data usage, information technology, statistical analysis, and mathematical models to enhance understanding of business operations.
Importance of Analytics
- Identifies opportunities in various domains, including:
- Assessing credit risk.
- Innovating in drug development.
- Optimizing product and service delivery.
- Preventing fraudulent activities.
- Detecting cyber threats.
- Enhancing customer retention.
Data Analysis Process
- Involves examining, transforming, and organizing raw data to extract useful information.
- Utilizes analytical reasoning for decision-making.
- Multi-faceted process encompassing various steps and techniques.
Data Analytics vs. Data Analysis
- Data Analytics focuses on predicting future events.
- Data Analysis examines historical data to explain past occurrences.
Demand for Data Analytics
- Increasing need for professionals skilled in analytics, with high salaries compared to traditional careers like engineering and accounting.
Roles in Data Analysis
- Data Analyst:
- Domain-specific roles (e.g., marketing, finance).
- Focuses on data exploration and actionable insights.
- Data Scientist:
- Applies advanced algorithms and machine learning.
- Engages in data product engineering.
Skills Required
- Key skills include technology proficiency, mathematical expertise, business acumen, and hacking skills.
- Essential for both Data Analysts and Data Scientists.
Python for Data Analytics
- Chosen for ease of learning, open-source availability, and extensive libraries.

- Data analysis.
- Machine learning.
- IoT and AI.
Jupyter Notebook Benefits
- Client-server application facilitating:
- Web-based code editing.
- Streamlined documentation and demonstrations.
- User-friendly interface.
Levels of Data Measurement
- Four levels of data:
- Nominal: Categories without ranking (e.g., gender, marital status).
- Ordinal: Categories with a rank order (e.g., satisfaction levels).
- Interval: Ordered scales with meaningful differences but no true zero (e.g., temperature).
- Ratio: Ordered scales with meaningful differences and a true zero point (e.g., weight, age).
Impact of Measurement Choice
- Statistical methods vary by data level:
- Nominal: Classified and counted; nonparametric methods.
- Ordinal: Involves ranking; nonparametric methods.
- Interval: Addition and subtraction applicable; parametric methods.
- Ratio: Multiplication and division possible; parametric methods.
