A) 5%
3.If a researcher is interested in making sure that all the questions that they have developed are indicative of the topic under study they may want to perform which type of statistical test:

4.What is the most important consideration in survey design when one is trying to obtain a high response rate?
A) Length of the survey
5.Why must researchers within health informatics be cautious when using a convenience sample?

9.What is the best reason to consider using an existing survey if it meets the goals and objectives of the research study?
A) Many times the existing surveys have been tested for reliability and validity.
10.How should the researcher determine if a new or existing survey should be used for their research project?
A) Review the literature to determine if an existing survey is available that meets the needs of their research project and objectives.
11.This type of sampling method draws the sample from a list of items such as diagnoses, ICD-10-CM codes, or discharges and selects every nth case. It is called:

15.What is one important way to increase the response rate in survey research?
A) Conduct appropriate follow-up methods
16.What is the Cronbach’s alpha?
A) A measure of internal consistency
17.Which types of scales have true numerical meaning?
A) Interval and ratio
18.Which types of questions are developed when the researcher wants to collect the “why” and “why not” type of responses?
A) Open-ended questions
19.The National Cancer Institute decided to develop a new survey called the Health Information National Trends Survey (HINTS) because:
