Question
Which of the following is an example of a way to improve the reliability of a research instrument?a.Use a larger sample sizeb.Use a different statistical analysis techniquec.Standardize the administration of the instrumentd.Change the research question
Solution
c. Standardize the administration of the instrument
This option refers to ensuring that the research instrument (like a survey or test) is administered in the same way to all participants. This can help to reduce variability in the results that might be due to differences in how the instrument was administered, rather than differences in what is being measured. This can improve the reliability, or consistency, of the results.
Option a, using a larger sample size, can improve the validity of the study, but not necessarily the reliability of the instrument itself.
Option b, using a different statistical analysis technique, might help to better analyze the data, but it doesn't improve the reliability of the instrument.
Option d, changing the research question, is not related to the reliability of the instrument.
