The Importance of Relationships

As its name implies, confidence intervals provide a range of values, along with a level of confidence, to

serve as an estimate of some unknown population value. Since it is rare to have access to the entire

population, you must frequently rely on the confidence interval of the sample to make some inference

about the population of interest. Before making accurate inferences to the population, we need to fully

understand how the three key components of the interval—variability in the data, sample size, and

confidence level—impact the width of the interval.

For this Discussion, you will explore the relationship between these components and understand the

trade-off between reducing risk in our confidence of estimates and increasing precision.

To prepare for this Discussion:

Review Chapters 7 and 8 of the Frankfort-Nachmias & Leon-Guerrero text and in Chapter 8, p. 256,

consider the 2012 Benghazi Terrorist Attack Investigation and focus on how different levels of confidence

and sample size work together.

Review Magnusson’s web blog found in the Learning Resources to further your visualization and

understanding of confidence intervals.

Use the Course Guide and Assignment Help found in this week’s Learning Resources to search for a

quantitative article related to confidence intervals.

Using the SPSS software, General Social Survey dataset and choose a quantitative variable that interests

you.

By Day 3

Using SPSS:

Take a random sample of 100.

Calculate the 95% confidence interval for the variable.

Calculate a 90% confidence interval.

Take another random sample of 400.

Calculate the 95% confidence interval for the variable.

Calculate a 90% confidence interval.

Post your results and an explanation of how different levels of confidence and sample size affect the

width of the confidence interval. Next, consider the statement, “Confidence intervals are underutilized”

and explain what the implications might be of using or not using confidence intervals. Provide examples

Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources

and other scholarly evidence in APA Style.

By Day 5

Respond to one of your colleague’s posts and explain how you might see the implications differently.
