Introduction to Secondary Quantitative Data Collection

Secondary quantitative data collection involves using existing numerical data collected by other people to conduct research. Researchers use existing datasets (according to specific methods) to conduct analyses rather than collect new information [1].

A common source of secondary quantitative data is research databases, public datasets, and survey information which make it an effective and efficient way to conduct modern research.

Understanding Secondary Quantitative Data in Research

Statistical data, often referred to as quantitative data, is numerical, measurable, and can be analyzed using statistical analysis to identify trends or associations.

Characteristics of Quantitative Data:

  • Numerical
  • Standardized and Structured
  • Capable of being Statistically Analyzed
  • Often Used to Compare or Forecast Results [2]

Quantitative Data Types:

Definition

Example

Discrete Data

Can be counted

Total Number of Employees Utilized at Any Given Time

Continuous Data

Can be measured

Temperature; Family Income

What is Secondary Quantitative Data Collection?

Secondary quantitative data collection involves analyzing existing numerical data instead of collecting new data.

Examples

Government census data

Online survey data

Research database

Simple Breakdown

 Data is already available

 Data was collected by another entity

 Data is reused for new goals 

Types and Sources of Secondary Data

There are various sources of secondary data:

Major Sources

  • Public Datasets – Government websites, census data
  • Research Databases – Research papers, academic journals
  • Survey Data – Market research reports, surveys
  • Statistical Repositories – World Bank datasets, WHO datasets [3]

Why Use Secondary Quantitative Data in Research?

By using secondary data, researchers can save time and money while at the same time having access to large-scale information.

Key Reasons

  • Faster than Primary Data Collection
  • Cost-Effective
  • Access to Historical Data
  • Enables Broader Statistical Analysis [4]
