10. In field experiments, researchers
A. formulate conclusions based on extensive field notes.
B. use treatment conditions that already exist naturally.
C. avoid confounding variables by exposing the same participants to all treatments.
D. randomly assign participants to treatment conditions in natural settings.
i answerd C
I don't think so.
is it B?
The correct answer is D. randomly assign participants to treatment conditions in natural settings.
To arrive at the correct answer, we need to understand what a field experiment is and how researchers conduct them. A field experiment is a type of research study conducted in a real-world setting, usually outside of a controlled laboratory environment. In field experiments, researchers manipulate independent variables and measure the effect on dependent variables, just like in a laboratory experiment.
However, unlike laboratory experiments where participants are typically assigned randomly to treatment conditions, field experiments often involve natural settings and existing conditions, making random assignment more challenging. This is because researchers cannot control or manipulate the environment as easily as they can in a laboratory setting.
Option A, formulating conclusions based on extensive field notes, is not specific to field experiments and can be a part of any research study where qualitative data is collected. Therefore, it is not the correct answer.
Option B, using treatment conditions that already exist naturally, can be a characteristic of field experiments, but it is not necessary. Field experiments often involve introducing treatment conditions rather than relying solely on existing conditions. Therefore, it is not the correct answer.
Option C, avoiding confounding variables by exposing the same participants to all treatments, is not typically done in field experiments. In field experiments, researchers aim to randomly assign participants rather than expose them to all treatments. Therefore, it is not the correct answer.
Option D, randomly assigning participants to treatment conditions in natural settings, is the most appropriate and accurate description of how researchers conduct field experiments. Random assignment helps minimize bias and ensures that any differences observed between treatment groups can be attributed to the independent variable being studied. Therefore, it is the correct answer.
