Considering in test-scoring "reliability" refers to the consistency of the test scores, and "validity" refers to the accuracy of the interpretations made from those scores, then reliability is possible without validity, although validity is not possible without reliability.

Satirical websites or sources with a known history of spreading misinformation would generally have the least validity. It's important to critically evaluate the credibility and reliability of sources before accepting the information as true.

What is Suitability Reliability Validity and Practicality in sport?

In sport, suitability is how relevant something is to the chosen sport; reliability refers to how consistent results would be if the test was to be repeatedly taken and validity refers to whether or not the test measures what it claims to. Finally, practicality refers to how appropriate the current environment is for carrying out the test.


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.


When you do an experiment is it important to have all measuring accurate?

Yes, it is important to have accurate measurements in an experiment because they can directly impact the validity and reliability of the results. Inaccurate measurements can lead to flawed conclusions and unreliable data. Using precise measuring instruments and techniques helps ensure the quality of the experiment.


What term deals with repeatability of measurement?

You may be thinking of reliability, as distinct from validity in the field of things like psychological measures. If the same value can be obtained repeatedly, within reasonable margins of error, and within other applicable conditions, then the measure can be considered reliable. That does not mean that the thing measured represents what it is hypothesized to measure. That would be the measure's validity.


Why would it be important to consider selection attrition and history?

Considering selection, attrition, and history is important because they can impact the validity and generalizability of research findings. Selection bias can affect the representativeness of the sample, attrition can lead to missing data and potential bias, and history can confound the results by external events occurring during the study period. By addressing these factors, researchers can improve the rigor and reliability of their findings.

What is the difference between a IQ test being reliable and it being valid?

Reliability and validity are both important yet different qualities of any measure, including IQ tests. Reliability has a number of different meanings. Reliability might refer to test-retest reliability, which means that you don't get wildly different results each time you take a test. Reliability also refers to the consistency with which observers interpret your results. You would not want two physicians disagreeing about the results of a lab test for cancer. Standardized IQ tests, such as the Stanford-Binet and Wechsler, typically hold up well in assessments of their reliability.Validity means that a measure measures what it is supposed to measure. In other words, does an IQ test really measure intelligence? Usually, validity is assessed by seeing if the results of a measure correlate with other similar measures. IQ scores and grades on academic work are positively correlated. Much of the debate surrounding IQ testing is due to different definitions of "intelligence" and discussions about what qualities an IQ test really measures.It is possible for a measure to be reliable but not valid. For example, your bathroom scale might tell you every day that you weigh 150 pounds, but your scale might be broken and your true weight at the doctor's office is different. It is not possible, however, to have validity without reliability.

What would happen if you change the manipulated variable?

If you change the manipulated variable in an experiment, it could lead to different outcomes or results than what was originally observed. This change may affect the relationships between variables being studied and could impact the validity and reliability of the experiment. It is important to carefully consider any modifications to the manipulated variable to ensure accurate and meaningful conclusions.


Why it is important to record and measure data accurately an experiment?

Accurate data recording and measurement are important in an experiment because they ensure the reliability and validity of the results. Precise data allows for correct conclusions to be drawn and for other researchers to replicate the study. It also helps in identifying any potential errors or inconsistencies in the experimental process.
