Topics in Understanding Data
1. Introduction to Data
- Data is a collection of characters, numbers, and other symbols that represents values of some situations or variables.
- Data is plural; the singular form is datum.
- People use data to make decisions in daily life, business, government planning, banking, sports analysis, and many other fields.
2. Types of Data
- Data can broadly be classified into two categories based on format: structured and unstructured.
- Structured data is usually stored in tabular form with rows and columns.
- In structured data, each column represents an attribute, characteristic, or variable, and each row represents one observation.
3. Data Collection and Data Processing
- Data collection means identifying already available data or collecting it from appropriate sources.
- Data may already be stored in a register, a digital file, or may need to be collected for a new system.
