Surveys

16.2K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Naturalistic Observations

16.6K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Survey Safety01:28

Survey Safety

221
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Convenience Sampling Method00:55

Convenience Sampling Method

10.0K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Summary
This summary is machine-generated.

Randomised Response Techniques (RRTs) improve data collection for sensitive conservation topics. However, RRTs in conservation studies were less effective at reducing bias compared to other fields, with common compliance issues noted.

Area of Science:

  • Ecology and Conservation Science
  • Social Sciences
  • Statistics

Background:

  • Conservation research often requires understanding sensitive human behaviors, which presents data collection challenges.
  • Specialized questioning methods like Randomised Response Techniques (RRTs) offer anonymity and reduce bias in such contexts.
  • Existing RRT literature is extensive, making it difficult for conservationists to navigate.

Purpose of the Study:

  • To systematically review and summarize Randomised Response Technique (RRT) designs.
  • To evaluate the empirical application and performance of RRTs in conservation and other disciplines.
  • To provide evidence-based guidance for conservationists using RRTs.

Main Methods:

  • Systematic literature review of RRT applications.
  • Analysis of 32 conservation studies and 66 studies from other disciplines.
  • Comparison of RRT-derived prevalence estimates with direct questioning and known behavior prevalence.

Main Results:

  • RRT applications in conservation have increased since 2000.
  • Conservation RRT studies were less likely to yield unbiased prevalence estimates than those in other fields.
  • Non-compliance with RRT instructions was frequently reported but often unaddressed in study design or analysis.

Conclusions:

  • Randomised Response Techniques (RRTs) are valuable for conservation but require careful design and implementation for optimal performance.
  • Guidance is provided on selecting appropriate RRT designs, improving efficiency, and enhancing compliance.
  • Alternate methods should be considered when RRTs may not be suitable or effective.
