Why is it important to replicate a research study?
When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings. If a researcher can replicate a study’s results, it means that it is more likely that those results can be generalized to the larger population.
Can antibiotics with the same mic have different tolerance levels?
Bacteria tolerating and these nontolerating antibiotics can have the same MIC. The strain is considered to display tolerance when an antibiotic at a concentration 32 times higher than the MIC does not contribute to 99.9% reduction in the number of bacteria used in the test (Minimal Bactericidal Concentration MBL / MIC > 32 mg/L) [51,54].
How could the psychologist use systematic replication to repeat the study?
A psychologist reads about an experimental study of a new treatment for depression and notices that it was only tested on men. How could the psychologist use systematic replication to repeat the study? She could repeat the study on a mixed group of men and women to see if the results of the depression treatment are the same. 2.
Is the MIC value sufficient to classify a strain as resistant?
However, due to epidemiological reasons, qualifying such a strain to resistant category according to the MIC value may be a trigger to undertake further research on the detection of resistance mechanism.
When is research replicable?
Research is replicable when an independent group of researchers can copy the same process and arrive at the same results as the original study. Hence, establishing its validity.
Why is it important to replicate research?
Research that has been shown to be replicable affords greater confidence in the results. It is also crucial that the process of replicating research is undertaken by independent researchers. This will reduce the chances of the research being influenced by selection bias or other dodgy elements.
What are two concepts that are closely related to the idea of replicable research?
Two concepts that are closely related to the idea of replicable research are. Reproducible research. This is research where another researcher can, given the original data, reproduce the findings. Replicability and reproducibility are commonly used as synonyms. Repeatable research.
Why is research considered replicable?
There are many potential explanations for different research findings. The most desirable explanation is typically that the research result is consistent with the theory because it is correct. However, there are many other explanations for findings: fraud, flukes, technical errors, and spurious correlations. For this reason, research is typically only regarded as being replicable when the findings have been reproduced using a methodology that is, in some important sense, different to that of the original study. Where a finding is found in multiple different ways it is said to be generalizable.
Can a study contain multiple findings?
If a study contains multiple findings, each finding must be assessed separately. While the failure to replicate one finding of a study will typically bode badly for the rest, it is not unusual to have only a subset of findings from a study be replicable.
What does it mean when a researcher replicates earlier research?
1 If the researcher obtains the same or similar results in follow-up experiments, it means that the original results are less likely to be a fluke.
What does it mean when a researcher can replicate a study?
If a researcher can replicate a study’s results, it means that it is more likely that those results can be generalized to the larger population.
Why do scientists want to replicate a study?
In other cases, scientists may want to replicate the experiment to further demonstrate the results.
How can replication be strengthened?
The Nobel Prize-winning psychologist Daniel Kahneman has suggested that because published studies are often too vague in describing methods used, replications should involve the authors of the original studies in order to more carefully mirror the methods and procedures used in the original research.
Answer
It is very important for scientists to replicate each other experiment because this will help to determine if important scientific results are repeatable. The correct option is Scientific results presented by a scientist should be reproducible anywhere in the world, without this, the results can not be accepted as theory.

How did the researchers make the laboratory chaotic?
The researchers made the laboratory chaotic by leaving garbage cans overflowing, not vacuuming, and not cleaning the computer stations where participants answered questions related to cognitive functioning.
How many stressor conditions are there in a stress experiment?
Participants are randomly assigned to the three stressor conditions and one control condition; in each of the stressor conditions, participants experience the same level of stress at the same time of day. Neither the participants nor the experimenter can tell which experimental condition the participants are in.
What is a researcher interested in?
A researcher is interested in the effects of natural disasters on mental health. She assesses people's mental health after a hurricane and compares the results to her results from a previous study examining people's mental health after an earthquake.
How to induce positive affect in participants?
In order to induce positive affect in the participants, the researcher exposes the participants in the experimental condition to a comedic film. The researcher then administers a survey to the participants in both the experimental and control conditions in order to assess their self-reported positive affect.
What is an experimenter?
Unintentional ways in which researchers influence their participants to respond in a manner consistent with the researcher's hypothesis are called experimenter: expectancy effects. When researchers repeat their own research in order to confirm the results of a previous study, this is an example of: a replication.
What is a debriefing study?
debriefing. In a study assessing the impact of depression on optimism, a researcher verbally administers a depression and optimism scale. During the day-long study, the researcher becomes ill but decides to continue the study because the subjects are already in the laboratory.

Why Should You Care That Research Is Replicable?
- In order to take a scientific study or experiment seriously, the results need to be able to be proven multiple times by independent researchers. If something is proven to be true once, why should you trust that it will always be true? Research that has been shown to be replicable affords greater confidence in the results. It is also crucial that the process of replicating research is undertaken …
