The case of Genie Wiley
Bilingualism
Deaf children who have their hearing restored by cochlear implants
Recovery from brain injury to language areas
You may also support your opinion with other relevant research findings of interest to you. (300 words and 2 reference).
2. Reliability and Validity
Create a 6-question survey on a topic of your choice. Please have the first 3 items as examples of good questions (e.g., open-ended for a qualitative study) and the last 3 as examples of poorly chosen questions (e.g., double-barreled or biased questions). Please identify at least 5 concepts from your text to explain why the good questions are good and why the poorly worded questions are bad.
Then, please discuss what reliability are and how they would relate to the survey. Specifically, note how inter-rater reliability, test-retest reliability, internal validity, and external validity could be used to determine the quality of the survey. Also, please provide a real-life example of when it is important to have strong inter-rater reliability (in your chosen field, or in other testing experiences that you have had).
