10. WHY WOULD A STATISTICIAN CONSIDER AN INFERENCE INCOMPLETE WITHOUT AN ACCOMPANYING MEASURE OF ITS RELIABILITY
Why would a statistician consider an inference incomplete without an accompanying measure of its reliability? Choose the correct answer below o A. The measure of reliability is a value probability assigned by the individual making the inference to indicate the accuracy of their inference; it is based on what they believe the strength of their research was and the quality of the sample. Without this value, there is no way to differentiate the validity of the inference from pure guessing....
what would be most appropriate for assessing the reliability of a measure of depression? Explain this type of reliability and what it is measuring and WHY it is the most appropriate choice for measuring depression. What would you recommend as an acceptable level of reliability (.90, .75, etc.) and why?
Describe the relationship between RELIABILITY and VALIDITY. Why is it possible to have reliability without validity but not vice versa?

Should we always consider a reliable measure as valid? Why or why not? Provide an example.
Be sure to consider (and give an example) how the economy would operate without financial markets, the benefits with/without financial markets, why society created them.

Why is PCR required before running the DNA on a gel? A Without PCR, there would be things in the DNA that would interfere with running it on the gel. B Without PCR, there would be too little of the DNA region of interest to see it on the gel. C Without PCR, the DNA region of interest would not be present because PCR adds the part that will be examined. D Without PCR, the gel would not have a...
