Gnesinka [82]2 years ago

In the confidence interval method the sample data must come from a population that is normally distributed with no outliers.

A confidence interval is a range of values derived from observable data at a desired level of confidence that may include the parameter's true value. The confidence level, such as a 95% confidence level, refers to the accuracy of the estimating process rather than the degree of assurance that the computed confidence interval accurately represents the true value of the parameter under investigation. Confidence intervals are typically written as (some value) ± (a range). The range can be expressed as a percentage or as a real amount. The equation used to determine the confidence interval varies depending on which standard deviation is known.

Regarding sensitive and complicated issues, which of the following is correct? Group of answer choices a) Use self-administered
ruslelena [56]

Answer:

b)

Explanation:

Sensitive issues refer to topics which people tend to feel uncomfortable talking about (Like harassment, addictions, violence)

Many studies on this topic have shown that when people are in front of other person who's interviewing them they might hide some aspects of themselves to create a better impression on the interviewer, therefore, the information acquired this way is not 100% right.

Regarding <u>sensitive issues, it is even more difficult for people to talk about them specially when it comes to an stranger</u> (like a researcher). Thus, it is not recommended to address sensitive issues in interviews but rather by <u>self-administered questionnaires in which the person doesn't have to interact with another person.</u>

<u />

When it comes to complicated issues, a questionnaire is not recommended since it could leave the researcher without enough information, and since it's <u>a complicated issue, the researcher might want to be there to clarify people's answers.</u> Therefore, <u>for complicated issues, it is better to use interviews.</u>

Thus, the correct answer is b) Use self-administered questionnaires for sensitive issues and interviews for complicated issues
