What is a Raw Data?

This data originates from various sources, including sensors, log files, surveys, and online transactions. Unlike processed data, raw data hasn’t been cleaned, corrected, or transformed, making it essential for analytics projects to start with reliable raw data. When processed, it leads to actionable insights and informed decision-making.

Raw data originates from diverse sources, including machinery, monitors, instruments, sensors, and surveys. These sources produce vast and complex datasets that may include errors from humans, machines, or instruments.

• Machinery: Industrial machines generate raw data for predictive maintenance and performance analysis.
• Monitors: Devices in healthcare and IT produce data for real-time monitoring and anomaly detection.
• Instruments: Lab instruments provide raw data for scientific research.
• Sensors: Widely used for monitoring, control, and decision-making.
• Surveys: Essential for market research and opinion polling.

Pros:

Raw data is vital across various domains, including scientific research, business analysis, and machine learning.

• Unaltered Source of Truth: Provides unbiased, original data.
• Flexibility: Allows tailored analysis to meet specific requirements.
• Informed Decision-Making: Enables accurate and comprehensive insights for strategic decisions.

Cons:

While advantageous, raw data also comes with cons:

• Inconsistencies and Errors: May contain inaccuracies that affect reliability.
• High Storage Costs: Managing vast volumes of data can be expensive.
• Processing Requirements: Extensive refinement is needed to extract meaningful insights.

Understanding the types of raw data helps differentiate between quantitative and qualitative forms, showcasing their unique applications and practical examples.

Quantitative data comprises numerical, countable information suitable for mathematical and statistical analysis. Common examples include:

• Customer Information: Enables targeted results and demographic insights.
• Sales Records: Tracks sales frequency and identifies trends.
• Employee Performance: Measures productivity and ROI.
• Revenue and Expenses: Tracks financial activity for ROI analysis.

Qualitative data is non-numerical and extracted through subjective methods. Examples include:

• Open-Ended Survey Responses: Capture respondent opinions.
• Photos and Videos: Essential for machine learning models.
• Customer Reviews: Offer insights into customer sentiments.
• News Reports: Provide public opinion insights.

Processing raw data involves transforming unstructured information into actionable insights through a series of systematic steps.

1. Data Preparation: Raw data often contains errors and inconsistencies due to its unstructured nature. During this step, data is cleaned, sorted, and filtered based on predefined standards to ensure accuracy and consistency.
2. Data Input: Raw data is converted into machine-readable formats for analysis. Digitally collected data requires minimal adjustments, while handwritten or multimedia data needs manual or digital extraction.
3. Data Processing and Analysis: Analysts identify trends, patterns, and anomalies using tools, AI, or machine learning to extract meaningful insights.
4. Data Output: Processed data is presented in user-friendly formats like graphs, tables, or plain text for actionable use.
5. Data Storage: Processed data is securely stored for future analysis, adhering to privacy laws like GDPR or CCPA.

Raw data encompasses various unprocessed information types such as website click rates, sales figures, survey responses, computer log files, social media posts, and more.

• Website Click Rates: Tracks user interactions with website elements.
• Sales Figures: Records the quantity of products or services sold.
• Survey Responses: Collects feedback from participants in its original form.
• Computer Log Files: Captures events occurring within computer systems.
• Social Media Posts: Includes user-generated content like comments and shares.

These examples highlight the diversity of raw data sources, offering valuable insights when processed for analysis and decision-making.
