Naturalistic Observations

18.1K
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...

Observational Studies

11.5K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Data Collection by Observations01:08

Data Collection by Observations

15.7K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

The Scientific Method

67.2K
Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.

Summary

Successful epidemiological field studies require strong community trust and rigorous data analysis. These elements ensure that collected data accurately represent the real-world health situations of the studied populations.

Area of Science:

  • Epidemiology
  • Public Health
  • Field Research

Context:

  • The author draws on over 40 years of experience in 18 epidemiological field studies.
  • Highlights include medical services in rural Okinawa, the Yusho episode, the JICA Onchocerciasis Control Project in Guatemala, and the Miyako cohort study.

Purpose:

  • To share key lessons learned from extensive epidemiological fieldwork.
  • To emphasize the critical factors for successful and accurate epidemiological research.

Summary:

  • Successful field epidemiology hinges on establishing strong human reliance between researchers and the populations under study.
  • Thorough examination and analysis of survey data are crucial for ensuring the data accurately reflect the real-world situation.
