Scientist are persuaded by logical arguments that are supported by evidence?
Logos refers to the process of persuading a person or group using supportive evidence. A researcher must conduct experiments using the scientific method, and generate reliable and valid results
Why is there a need to conduct research in the field of medicine?
for the end results to be accurate and reliable
When is the measurement of turbidity a reliable indication of the number of viable cells per ml?
It is reliable for validity only when most of the cells are still valid (alive); therefore before the stationary phase (in the Log or Lag phase it would be viable).
What is the simple and reliable measurement system called?
This is the SI (International System of Units); the system is valid in the majority of countries excepting USA, UK and ancient UK colonies.
What is the difference between valid and reliable results?
Reliable - . i remember this by using the 4 A's rule: search for accuracy, average and do the experiment again, discard AnomaliesValidity - i remember this with the 3 C's rule: Cross-check ( compare with internet experiments or a classmate) calibration of equipment( starting the timer at 0.00), and the control variable( what you keep the same)hope this helped :)
Why is it possible to have a reliable measure that is not valid but impossible to have a valid measure that is not reliable?
A test can be reliable and not valid. A test cannot be valid and not reliable.
Is a reliable test necessarily valid?
In my view reliable test is always valid.
Is it possible for an operational definition to be valid but not reliable?
Is it possible for an operational definition to be valid but not reliable
A test may be reliable but not necessarily validIs it possible for a test to be valid but not reliable?
No, for a test to be valid, it must also be reliable. Reliability refers to the consistency of the test results, while validity refers to the accuracy of the test in measuring what it is supposed to measure. A test cannot be valid if it is not reliable.
What are various databases that can be used to conduct a literature review?
We can use wiki how, google, libraries, books, journals, magazines, etc to conduct a literature review.
Can a test be reliable and yet not valid?
A test may be reliable yet not valid, The results can end up being reliable, in other words certain to have yielded properly based on input. But the results may not be trustworthy.
Sampling techniques can provide statistically reliable and valid survey results except?
Sampling techniques can provide statistically reliable and valid survey results except haphazard sampling.
What is the difference between slection crieteria and validity and reliability?
Social and Medical sciences uses these statistical concepts. ideally, we have to measure the same way each time, but intrasubject, interobserver and intraobserver variance occur, so we have to anticipate and evaluate them. In short, it is the repeatability of a measurement, by you, myself and everybody person or instrument. Validity is how much the mean measure that we got is near of the true answer or value. So, an instrument can be reliable but not valid, valid but not reliable, both valid and reliable, nor valid neither reliable. I suggest that you imagine a target: you can aim and 1) always get the center (both valid and reliable) 2) always get the same distant point (reliable but not valid) 3) err much around the true center (valid but not reliable - the mean and median of your arrow's shot will get the center) 4) err much around the another center, false one (nor valid neither reliable) I did not understood exactly what selection criteria have to do with the rest of question, so, left in blank ;-)
What is not the purpose of peer review in scienece?
to conduct secret research
What are the steps in making a valid conclusion?
You first have to come up with a hypothesis. Review the relevant work already completed out there. Design an experiment around to test your hypothesis. Conduct the experiment and analyze the results. Write a summary report. Using the data from the experiment to evaluate the hypothesis in order to draw a valid conclusions.
Why Peer review important when publishing experimental results?
peer review makes the result more reliable
Scientist are persuaded by logical arguments that are supported by evidence?
Logos refers to the process of persuading a person or group using supportive evidence. A researcher must conduct experiments using the scientific method, and generate reliable and valid results
