Study Notes
- Data serves as the base for analyses, interpretations, and decision-making in quantitative reasoning.
- A comprehensive grasp of data types and sources is crucial for effective quantitative analysis.
Types of Data
- Data can be divided into quantitative and qualitative types.
Quantitative Data
- Quantitative data is comprised of numerical values for quantities or measurements.
- It can be discrete (distinct values) or continuous (values within a range).
- Examples include height (e.g., 165 cm), temperature (e.g., 25.5°C), income (e.g., $50,000 per year), and test scores (e.g., 85 out of 100).
Qualitative Data
- Qualitative data involves non-numeric descriptors representing qualities or characteristics, acquired through methods like observations, interviews, or surveys.
- Examples include gender (e.g., male, female), marital status (e.g., married, single), opinion (e.g., agree, disagree), and preference (e.g., favorite color).
Primary Data
- Primary data is firsthand information researchers collect for their specific research.
- Collection methods include surveys (questionnaires for participant responses), experiments (controlled studies manipulating variables), and observations (systematic recording in natural settings).
Secondary data
- Secondary data is that which was previously collected by others for purposes unrelated to the current research.
- Sources include published research studies, government reports and databases, historical records and archives, company financial statements, and social media and web data archives.
Sources of Data
- Data sources encompass surveys/questionnaires, experiments, observational studies, administrative records, publicly available datasets, interviews/focus groups, and social media/web data.
Surveys and Questionnaires
- Surveys and questionnaires are used to collect data from individuals or groups.
- Examples include customer satisfaction surveys, employee feedback questionnaires, market research surveys, and political opinion polls.
Experiments
- Experimental data is gathered through controlled studies with manipulated variables.
- Examples include drug trials, laboratory experiments in psychology/physics, and field experiments in environmental science/agriculture.
Observational studies
- Involve observing and recording behaviors, events, or phenomena as they naturally occur.
- Examples are ethnographic studies, wildlife observation, and longitudinal studies.
Administrative records
- Comprise data collected by organizations or institutions for administrative or record-keeping purposes.
- Examples include census data, employment records, academic transcripts, and medical records.
Publicly available datasets
- Are accessible sources of data from government agencies, research institutions, and organizations.
- Examples include census data, economic indicators, climate data, and social surveys.
Interviews and Focus groups
- Entail direct interaction to gather insights, opinions, or experiences.
- Includes interviews with stakeholders/experts, focus groups for consumer/product feedback, and oral history interviews.
Social media and web data
- Is generated through user interactions on platforms, websites, and forums.
- Examples include sentiment analysis of Twitter posts, web scraping of online reviews, and analysis of forum discussions.
