SOCI 332 APUS Test of Significance Job Satisfaction Paper
In Week 4, we used epsilons and 10-percent-point rule to determine if a potential relationship between two variables is worth examining further. During Week 5, we studied tests of significance. In this week's discussion, we will apply these tests of significance to our project variables. We will also run measures of association to determine the strength and direction of the relationship between our variables. As we discussed previously, the levels of measurement of our variables determine which test of significance works for the research project. Here is the guideline: 1. Before-and-after design and the DV is at I/R level: Dependent Sample T-test2. DV and IV are BOTH categorical variables (nominal/ordinal): Chi-square*Special note for Chi-square: you should have less than 20% of the cells with an expected count of 5 or less. This information is reported automatically, right below the chi-square output table. If your chi-square test fails to meet this requirement, it is necessary to use "recoding" to combining certain answer categories together so the expected counts would increase. 3. DV and IV are both continuous (interval/ratio) variables: regression4. Comparison of groups (when IV is categorical - nominal/ordinal and DV is continuous - interval/ratio): a. Between 2 groups: Independent Sample T-test b. Among 3 or more groups: ANOVAWhy do we need to run tests of significance?They allow us to see if our relationship is "statistically significant." To be more specific, these tests tell us if a relationship observed in a sample, like your research project based on GSS 2016 data set, is generalizable to the population from which this sample was drawn (US adults).Test results reported under "p" in the SPSS output tells us the chances that a relationship observed in the sample is not real, but rather due to factors like a sampling error. We compare this "chance" with level of significance, commonly set as .05 or .01. If this chance is smaller than level of significance, we can reject the null hypothesis, and keep the research hypothesis.Next, we'll use tests of "measures of association" to figure out the exact strength of a relationship between two variables. In addition, we'll learn how to interpret SPSS outputs for measures of association tests such as lambda, gamma, and Pearson's r, along with other possible tests. These tests are also specific to the level of measurement of your variables. Here are the guidelines:Both DV and IV are nominal variables: Lambda (when it is not a 2X2 table)If it is a 2X2 table: PhiBoth DV and IV are ordinal variables: GammaOne variable ordinal AND the other variable dichotomous nominal (like Yes/No, male/female, etc.): GammaOne variable ordinal AND the other variable nominal (not dichotomous, has more than 2 categories): Cramer's V.Both DV and IV are I/R variables: Pearson's rTo interpret the output, see attached handout. Keep in mind measures of association is a statistical procedure based on Proportional Reduction of Error (PRE). Thus the format of interpretation will be: Knowing the IV will reduce error in predicting the DV by *%. Please note: Don't just say "IV" and "DV" in your explanation. You need to enter your variables names for IV and DV, and replace * for the exact test value from the output. If the value of Lambda is .34, then it will be interpreted as 34%.****Ok, now it is time for you to try! For this week's discussion, be sure to perform the correct test of significance (choose one) and measure of association (choose one) on your variables for the final project. You can download the class handout attached at the bottom of the page.This week in the discussion:I. You will decide which test of significance you will use for your project. Use the guideline above to make your choice.II. You will use the process for hypothesis testing which outlines five steps:Write your research hypothesis (H1) and your null hypothesis (H0).Identify and record your level of significance (alpha): either .05 or .01.Complete the significance test using SPSS. (Include the output of the analysis (table) in your post.)Identify the number under Sig. (2-tail). This will be represented by "p." Compare the numbers in steps 2 (alpha) and 4 (p) and apply the following rule:If p < or = alpha, than you reject the null hypothesisDetermine what to do with your null and explain this to your reader. Be sure to go beyond the phrase "reject or fail to reject the null" and explain what that means to your research.III. You will decide which measure of association you will use for your project. Use the guideline above to make your choice. Include the output (table) in your post. Based on the output, describe the strength and direction of the relationship between the variables. Also explain the PRE.**** I have attached information about my variables "satjob1 and happy". the gss 2018 spreadsheet that contains both my variables and a helpful handout from class.

Problem Set: Inventory Aggregation
Your friend Jane, an entrepreneur living in Boston, needs your help. Jane is considering opening an online store
to sell a product that will have a logo of one of the top universities in Boston. She is very secretive at this point
and will not tell you the type of product – just that it comes in five colors and will contain one of the 8 logos (i.e.,
there are 40 different configurations of the product). She asked another friend to make demand forecasts. The
forecast indicates level demand over the year, with the average weekly demand and the standard deviation of
the weekly demand forecast shown in Table 1. Demand will be independent across products but demand will
be positively correlated over time.
Table 1: Demand Forecast
Jane has also contracted with an offshore manufacturing facility to produce the products. Their lead-time
agreement specifies that ordered products will be received 12 weeks after the order is placed. Jane will place
orders on a weekly basis (once per week). Jane has the option of printing the logo herself (after a customer
places an order) or having the offshore supplier print the logo. She estimates her average printing cost to be
$0.75 per unit. Unfortunately, because the supplier’s manufacturing processes are typically setup to include
printing, there will be no decrease in supplier production costs if Jane prints the logos. The offshore production
costs per unit are shown in Table 2.
Offshore Poduction Costs
Table 2: Production Costs
Jane needs help with inventory planning. In particular, she has two options in mind. The first option will consist
of holding final product inventory for all 40 of the product configurations. She likes this option because she
would be able to immediately ship products to customers. The second option would consist of holding inventory
of the five product colors, and printing the university logos herself before shipment to customers. She likes this
option because it simplifies inventory requirements.
For this assignment, create an Excel spreadsheet to evaluate the two options. The comparison should compare:
(a) the annual holding cost of safety stock for the “no aggregation” option, where all 40 final product
configurations are held in inventory, and (b) the annual holding cost of safety stock plus the increased printing
cost for the “aggregation” option, where inventory is held by color so that only 5 different items are held in
inventory. When analyzing the two alternatives, use a target product fill rate of 99%.
After explaining inventory holding costs to Jane, you agree to use an annual holding rate of 35% for your
analysis because jane will need to rent warehouse space. However, this value is uncertain. So, you agree to use
a graphical display to show her how the options compare if the annual holding rate is changed over a range from
15% to 50%.
The assessment of this work will be based on the accuracy and clarity of your spreadsheet and the graph.
