Reliable - . i remember this by using the 4 A's rule: search for accuracy, average and do the experiment again, discard Anomalies
Validity - 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 :)
What else can I help you with?
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.
Why it is important to distinguish valid and faulty generalizations?
Distinguishing between valid and faulty generalizations helps ensure that conclusions drawn from specific instances are accurate and reliable. Valid generalizations are based on sound reasoning and evidence, while faulty ones can lead to misinformation and unfair judgments. By being able to identify the difference, we can make better decisions and avoid stereotyping or making misleading assumptions.
The same throughout the solution?
If the solution remains consistent throughout, it suggests that the methodology or approach used is reliable and valid. It helps ensure the accuracy and consistency of the results obtained.
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 type of observation involves collecting research data under controlled conditions?
Experimental observation involves collecting research data under controlled conditions. This allows researchers to manipulate variables and establish cause-and-effect relationships between them. By controlling for external factors, experimental observations aim to provide more valid and reliable results.
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.
Psychological tests that yield relatively consistent results are said to be?
valid
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.
A test may be reliable but not necessarily validIs it possible for a test to be valid but not reliable?
A test may be reliable but not valid. A test may not be valid but not reliable. For example, if I use a yard stick that is mislabeled to measure the distance from tee to hole in golf on different length holes, the results will be neither reliable nor valid. If you use the same stick to measure football fields that are the same length the result will reliable (repeatable, consistent) but not valid (wrong numbers of yards). There is no test that is unreliable (repeatable, consistent) and valid (measures what we are looking for).
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 does a reliable experiment mean?
A reliable experiment is one that can be proven or has been worked out several times giving valid or dependable results.
How can an instrument be reliable but not valid?
An instrument can be reliable but not valid when it consistently produces the same results under the same conditions, indicating stability and precision, but does not measure what it is intended to measure. For example, a scale that consistently weighs a person's mass the same way might be reliable, but if it is incorrectly calibrated and always adds five pounds, it is not valid for assessing true weight. Thus, while the results are dependable, they do not accurately reflect the intended construct.
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
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 the difference between valid and reliable?
I think that with reliability we mean that the plans tha you propose are based on some spesific and realistic elements. With validity I think that we mean that these elements are true and modern.
