MTH 218 University of Phoenix Wk 5 US 2020 Census Statistics Discussion
Respond to the following in a minimum of 175 words:
Given what you have learned so far in the course, what are some ways you could use your statistics knowledge to work with census data?
What limitations would you have if you were using the simple procedures addressed in Wks 1-4 of this course?
What additional statistical knowledge might be helpful to enhance your analysis?
Post 2 replies to classmates or your faculty member. Be constructive and professional.
**This was the original question and I need to reply to my classmate in a minimum 100 words without references:
This is a classmate's response to the above discussion question:
"The U.S. census is a method of data collection which can then be analyzed with statistical knowledge similar to what we’ve done in the last few weeks. The U.S. Census Bureau counts every member of every household thus resulting in the total population. T-tests can be used to make inferences about the population based on samples. ANOVA tests can be conducted to test multiple parameters, providing information about American demographics which the government uses for budget reallocation. The limitations with hypothesis testing for this type of analysis is you’re not getting the whole picture and the sample size matters. For example, if the total population is 350 million people, you would need a massive sample size to make an accurate inference about the population. It might be helpful to break down the data to men and women, or by age group, but you would still need a significant sample size to garner accurate results. Another limitation is the census only publishes statistics for cities and towns with a population of at least 5,000 people. Though this may not impact results, it should still be noted as a limitation of the analysis. The other limitation I see with census data is accuracy because you are expecting everyone to be 100% honest in the surveys which is just not realistic. I’m not sure the census bureau can verify every survey to ensure everyone was stating factual data."

consider the use of dummy variables.-Create a research question using the General
Social Survey dataset that can be answered by multiple regression. -Using the SPSS software, choose a categorical
variable to dummy code as one of your predictor variables.Estimate a multiple regression model that answers your
research question. Post your response to the following:-What is your research question?-Interpret the coefficients for the model,
specifically commenting on the dummy variable.-Run diagnostics for the regression model. Does
the model meet all of the assumptions? Be sure and comment on what assumptions
were not met and the possible implications. Is there any possible remedy for
one the assumption violations?

5388 The University of Texas at Arlington Statistics in healthcare week
This week we will discuss great research questions for predictive designs. A great research question will include all of the variables, identify the predictor and outcome variable, and will imply the measurement scale of the variables. A great research question will also give you enough information to know what statistic(s) will be appropriate to answer the question. The topic for this week's forum is finding a GREAT research question or research hypothesis from an empirical study. It should be so thoroughly stated that we would all be able to have a good idea of the measurement scale of the variables – all of them should be at least ordinal to require linear regression. GUIDELINESPlease copy and paste ONE question/hypothesis (great ones will be one sentence only) and list the citation. Then tell us why YOU believe the variables involved are ordinal/interval/ratio, and WHY regression – in your words. Please make your postings brief by writing succinctly.
