Study Notes
Data Analytics Overview
- Data Analytics involves collecting and analyzing information to tell a story and convey insights clearly to various stakeholders.
- It supports everyday decision-making on a larger scale, enabling complex choices based on data.
- The process includes identifying a problem, forming a hypothesis, and testing it through data collection, cleaning, analysis, and presentation.
Key Analytics Types
- Descriptive Analytics: Answers "What happened?"
- Diagnostic Analytics: Explains "Why it happened?"
- Predictive Analytics: Forecasts "What will happen next?"
- Prescriptive Analytics: Suggests "What should be done next?"
Key Steps in Data Analysis
- Understanding the Problem: Begin with a clear definition of the problem and desired outcomes.
- Setting a Clear Metric: Establish measurable criteria (e.g., regional sales over a specific period).
- Gathering Data: Identify necessary data sources and tools for analysis.
- Cleaning Data: Resolve quality issues such as missing values and outliers for accuracy.
- Analyzing and Mining Data: Explore cleaned data for patterns, trends, and correlations.
- Interpreting Results: Evaluate findings while considering limitations and objections.
- Presenting Findings: Communicate analyses effectively through reports, dashboards, and charts to support decision-making.
