Any method of scientific investigation is accepted on the basis of?
Its ability to generate reliable and valid results, adhere to ethical standards, and be subject to peer review and replication by other researchers.
Explain the process you would go through to make your instrument valid and reliable?
To ensure validity, I would review the instrument's content to ensure it aligns with the construct being measured. For reliability, I would conduct a pilot test to assess consistency in measurements over time and among different raters. I would also use statistical analyses, such as Cronbach's alpha for internal consistency or test-retest reliability, to further assess the instrument's reliability.
What is the manner in which scientists intend to conduct an experiment?
Scientists intend to conduct an experiment by following a structured methodology that begins with defining a clear research question or hypothesis, designing a controlled experiment to test the hypothesis, collecting and analyzing data, and drawing conclusions based on the results. The experiment should be carefully controlled to minimize bias and ensure reliable and valid results.
Scientist are persuaded by logical arguments that are supported by evidence?
Yes, scientists rely on logical arguments that are supported by empirical evidence to establish the validity of their hypotheses and conclusions. This evidence-based approach is fundamental to the scientific method and helps ensure that scientific conclusions are reliable and reproducible.
What word describes the steps used in an experiment?
The word is "methodology." It refers to the systematic approach or procedure followed in conducting an experiment to achieve reliable and valid results.
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.
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 reliable measure is consistent and yields consistent results, so it may not be measuring the intended construct accurately (lack validity). On the other hand, a valid measure accurately assesses the intended construct, but it must be consistent and produce stable results (reliable) to ensure that the measurements are dependable and trustworthy.
Any method of scientific investigation is accepted on the basis of?
Its ability to generate reliable and valid results, adhere to ethical standards, and be subject to peer review and replication by other researchers.
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.
What is the difference between a valid test and a reliable test?
Reliable indicates that each time the experiment is conducted, the same results are obtained (accuracy). Valid indicates the experiment (or test) has controlled variables and used an appropriate method/model.
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.
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.
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
Why Peer review important when publishing experimental results?
peer review makes the result more reliable
