RSCH Walden University Week 2 Quantitative Reasoning and Analysis Discussion
To prepare for this Discussion:Review the Learning Resources for this week related to frequency distributions and graphic displays of data.Using the SPSS software, open the General Social Survey dataset found in this week’s Learning Resources.Next, create a figure or table from a few selected variables within the dataset. Finally, think about what is good about how the data are displayed in the figure or table you created and what is not so good.BY DAY 3Post your display of the table or figure you created and provide an explanation of why this would be the best way to display the data provided, include the General Social Survey Dataset’s mean of Age to verify the dataset you used.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.From professor DiscussionThe Discussion instructions ask you to generate “a figure or table from a few selected variables” (Laureate Education, n.d., para. 1). Please follow these revised instructions.Post only One figure or graph of One variable to the discussion. Also, please be sure you use the GSS data set and clearly indicate the variable used. Please include the name of the variable as it appears in the data set. Use the Variable View to select your variable. IfFor example, the variable entitled sex is the variable name and RESPONDENTS SEX is the variable label. The value labels are 1 (male) and 2 (female). You could write something like:Figure 1 shows a bar graph of the respondents sex (sex). Participants responded 1 (male) or 2 (female). Sex is a nominal variable. Notice the APA format for reporting the value labels for male and female. These are called scale anchors. You can read more about this formatting in your APA manual. Warning! Ensure the graph you select is appropriate for the level of measurement for your variable (nominal, ordinal, scale [interval or ratio]). The readings will help with this concept.For help with SPSS and generating graphs for this week’s discussion, refer to the video for SPSS. The data set they use is similar to our GSS data set – so you might find it beneficial to open SPSS, open the GSS data set, and follow along with the video. Remember you can stop and start the video as you find the variables he uses. One variable he used didn’t appear exactly the same in our data set. When he uses number of hours worked last week – you can use number of hours usually work a week (hrs2) and it will be very similar. You should also refer to the Wagner (2016) text for additional support.Hint: when he says to click a graph and drag it to Chart Gallery, you must left-click the mouse and hold it down while you drag it to Chart Gallery. Just clicking won’t do you any good. Click-hold-drag! :)Hint: to insert the image of your graph into the discussion boardCopying SPSS Output into Discussion BoardsThe best solution we’ve found is to select the graphs or tables from the SPSS Output using the snipping tool, and save them as JPG files. Then insert the JPG file into the discussion board. If you are not familiar with the snipping tool, here is a resource to help with that. It is pretty easy to pick up. https://www.youtube.com/watch?v=uL3h5xns6DMInsert graph into discussion board1– Begin your main post2 – Insert the JPEG file into your post by using the picture tab.

Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree. The signature assignment may be graded with an automated rubric that allows the University to collect data that can be aggregated across a location or college/school and used for program improvements. Purpose of Assignment The purpose of this assignment is for students to synthesize the concepts learned throughout the course, provide students an opportunity to build critical thinking skills, develop businesses and organizations, and solve problems that require data. Assignment Steps Case 1: Scenario: Cloud Data Services (CDS), headquartered in Memphis, provides information technology services, specifically application hosting services in the cloud for several clients in the southern United States. CDS hosts software applications on their network servers. While CDS has achieved great success and customers rate CDS's services highly, lately, some customers have been complaining about downtime on one of the primary network servers. The given dataset, found in the Signature Assignment Excel® Template, contains the downtime data for the month of November.Use the data analytics skills learned in Week 3 and analyze the downtime data.Make a short presentation to CDS's management including the following:1.Using used Microsoft® Excel® Pivot Tables, construct a frequency distribution showing the number of times during the month that the server was down for each downtime cause category.2.Develop a bar chart that displays the data from the frequency distribution in part 1.3.Develop a pie chart that breaks down the percentage of total downtime that is attributed to each downtime cause during the month.4.Evaluate the mean, median, standard deviation, and variance of the downtime minutes for the month of November.Case 2:Note: Although you will be studying the concept of CPI in more detail in your ECO/561 class; for the purpose of this case, you need to use the concepts of percentages, percentage increase/decrease, and creating and interpreting line charts to compute the inflation rate in the US economy and determine which time period experienced the highest inflation rate. Follow the steps below to complete this signature assignment: 1.Search for the Federal Reserve Bank of St. Louis (FRED).2.On the home page of the website, you will see a search box.3.Type in CPI- AUCSL in the search box and press the return key.4.The first result of the search will be "Consumer Price Index for All Urban Consumers: All Items." Click on this result link.5.Click on the Download link and download the data in Excel®.6.On the Excel® file, the second column gives you the CPI values for each period starting from 1947.7.Go to the last row and notice the last date and the CPI value. Go back 6 years from this last date. For example, if the last date is 2016-11-01, then the date 6 years ago would be 2010-11-01.8.Copy and paste this six years data into a separate Excel® tab.9.Using Excel®, calculate the percentage change in CPI from a year earlier for each observation, beginning with the observation one year later than the first observation. To make this calculation, click on the blank cell next to the observation corresponding to that date and then use Formula 1, located in the Signature Assignment Excel® Formulas document (note that in Excel®, the symbol for multiplication is *), where t-1 is the first observation and t is the observation one year later. For example, to find the percentage change in CPI from 2010-11-01 to 2010-10-01, refer to Formula 2 located in the Signature Assignment Excel® Formulas document. Convert this value to a percentage in Excel®. Repeat this process for the remaining observations (you can use the copy and paste functions to avoid having to retype the formula).10.This new column contains the national inflation rate.11.Create a line graph of the percentage changes (inflation rates) from a year earlier.12.Which period experienced the highest inflation rate? What was the inflation rate during that period?Format your assignment consistent with APA guidelines. Click the Assignment Files tab to submit your assignment.
