Question
Whenever possible, it is advisable to use instruments that have already been developedand repeatedly used in published studies, rather than developing our own instruments forour studies. Do you agree? Discuss the reasons for your answer.
Solution
Yes, I agree with the statement to a certain extent. Here are the reasons for my answer:
-
Validity and Reliability: Instruments that have been developed and used in published studies have already been tested for their validity and reliability. This means that they have been proven to measure what they are intended to measure and produce consistent results.
-
Time and Resource Efficiency: Developing a new instrument can be a time-consuming and resource-intensive process. It involves designing the instrument, testing it, and validating it. Using an existing instrument can save a lot of time and resources.
-
Comparability of Results: Using the same instruments allows for the comparability of results across different studies. This can contribute to the accumulation of knowledge in a particular field.
However, it's important to note that using existing instruments may not always be the best approach. There are situations where developing a new instrument may be necessary. For instance, if the existing instruments are not suitable for the specific context of your study or if they do not measure the variables you are interested in, you may need to develop your own instrument. Also, using an existing instrument may limit the scope of your study to what the instrument can measure. Therefore, the decision to use existing instruments should be based on the specific needs and context of your study.

Review the claim and the two pieces of evidence.Learning to play an instrument can help you succeed academically.Evidence A: Researchers at Boston Children's Hospital scanned the brains of musicians and non-musicians while they completed various tasks. Musicians showed increased brain activity in areas that could strengthen school performance.Evidence B: A long-term study at a top research university showed that children who had learned to play an instrument in the past year had greater self-confidence than those who had not.Why is Evidence A stronger than Evidence B?Evidence B does not directly support the claim. It does not show that playing an instrument improves brain performance or intelligence.Evidence B does not come from a credible source. The results of this study are unreliable and cannot tell us anything about the effects of learning to play an instrument.Submit
