Review Questions

• How do different data collection methods impact the validity and reliability of the results?
  • Different data collection methods can affect validity and reliability in various ways. For example, surveys may introduce response bias if questions are poorly designed or leading. Observational studies can provide real-world insights but may be influenced by external factors that could skew results. In contrast, controlled experiments aim to minimize variables to enhance reliability. Understanding these impacts helps in choosing appropriate methods for accurate results.
• Discuss how ethical considerations play a role in the data collection process.
  • Ethical considerations are critical in data collection as they ensure the protection of participants' rights and well-being. This includes obtaining informed consent, ensuring confidentiality, and being transparent about how data will be used. Violating these ethical principles can lead to harm for participants and undermine the integrity of the research. Therefore, it’s essential to establish ethical guidelines before initiating any data collection effort.
• Evaluate the influence of technology on modern data collection practices and its implications for business decision-making.
  • Technology has transformed data collection practices by enabling faster and more efficient methods such as online surveys and automated data scraping. This has allowed businesses to gather large volumes of data quickly, enhancing their ability to make informed decisions based on real-time insights. However, reliance on technology also raises concerns regarding data privacy and security, highlighting the need for businesses to balance innovation with ethical responsibility when collecting and using data.
