KT0301: Sources and Collection Systems

What are the main sources of data?

  • Primary data: Original data collected directly from official sources through techniques like surveys, questionnaires, and interviews.
  • Secondary data: Second-hand information that is collected from published or unpublished sources (e.g., data from reports, books, or databases).

Sources of Data

  • Statistical sources: Official sources such as censuses and surveys conducted for public administration or research purposes.
  • Non-statistical sources: Data collected for administrative, business, or private sector use.

Types of Sources of Data:

  1. Internal Sources: Data collected within an organization, such as reports, sales data, and internal surveys.

  2. External Sources: Data collected from outside the organization, such as government reports, industry studies, or data from partner companies.

KT0302: Data Capturing Systems and Processes

What is a Data Capture System?

A data capture system is a method used to collect, store, and manage data electronically. This is typically done via software, such as Electronic Data Capture (EDC) systems in clinical trials or customer data management systems in businesses.

Methods of Data Capturing:

  • Optical Character Recognition (OCR): Converts scanned text into machine-readable data.

  • Intelligent Character Recognition (ICR): Reads handwritten text and converts it into machine-readable form.

  • Automatic Data Capture: Software that extracts key data from forms, invoices, and documents.

  • Paperless Forms: Mobile devices that capture data and transfer it directly into digital systems.

  • Barcode Technology: Data is captured through barcodes, reducing manual entry.

KT0303: Parameters for Data Capturing Systems and Processes

What is Data Capture?

Data capture is the process of collecting and converting structured or unstructured data into a digital format, making it accessible for analysis and further use.

Challenges in Current Data Capture Processes:

  • Increased Error Rate: Errors can occur due to incorrect data entry, lack of proper training, and misinterpretation of data.

  • High Costs: Manual data entry can be expensive due to labor, training, and system setup costs.

  • Time-Consuming: Manual data entry is often slow and prone to errors, delaying data availability.

How to Capture Data?

  • Manual Data Capture: Data is entered by individuals manually into systems.

  • Automated Data Capture: Uses technologies like OCR, ICR, and AI to automate the extraction of data from documents and forms.

KT0304: Maintenance of Data Capturing Systems and Processes

How Can Data Capturing Be Improved?

  1. Concentrate on Useful Data: Focus on collecting only relevant and accurate data to avoid data overload.

  2. Analyze Errors: Regularly assess and correct data entry errors to maintain accuracy.

  3. Standardize Processes: Implement consistent data collection and verification methods to ensure high-quality data.

  4. Introduce Smart Automation Tools: Use tools like Machine Learning to automate and enhance data collection.

  5. Provide Feedback: Continuously monitor and refine data collection processes based on feedback to improve accuracy.
