Quality measurement in research is essential. Measurement involves assigning numbers to concepts, objects, events or situations following a set of rules derived by the researcher through instrumentation or the use of tools for measurement. These measurements should be accurate and consistent. Chapter 16 in Gray, Groces and Sutherland (2017) explains the way that validity and reliability can be achieved. Check out page 371.

GMT - 05: Question 1 100 /^100 pts A researcher develops a new instrument to measure coping skills and conducts a pilot study to compare the new tool with an existing tool that measures this concept. Convergent validity
Coorrrecctt! (^) A researcher performs a series of pilot studies to evaluate whether a measurement tool produces consistent results. Coorrrecctt! (^) A researcher develops a 7- point Likert scale to evaluate feelings of well- being in patients who are undergoing chemotherapy. The researcher administers this measure to other, similar patients in other medical centers. Coorrrecctt! (^) In a research study, ambulatory clinic nurses teach children with asthma how to monitor peak expiratory flow volumes and how to use metered- dose inhalers to determine whether asthma control scores improve. The researcher discovers inconsistencies in how these measures were taught and how well the children understood the concepts. Coorrrecctt! (^) A researcher reviews demographic characteristics of potential study subjects, such as age and gender, to determine whether these This stu adcehd^ bayr^1 a^00 c^0 t^0 e^08 r^2 i^6 s^02 t^0 i^7 c^8 s^4 frmomaCyour^00 Test - retest reliability Intervention kdelity Internal validity
researcher examines the reliability of the scores of each data collector. Coorrrecctt! (^) A researcher evaluates scores of a paper and pencil instrument with variables at the interval level of data using the Cronbach’s alpha coefficient statistical procedure. Coorrrecctt! (^) A researcher evaluates whether a tool addresses the major elements of the construct being studied. Coorrrecctt! (^) A researcher develops a new instrument to measure coping skills and conducts a pilot study to compare the new tool with an existing tool that measures this concept. Coorrrecctt! (^) A researcher administers a scale measuring self- confidence and one measuring self-doubt to a group of subjects and performs a correlational analysis of the results. Coorrrecctt!
