  3. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 1 DQ 1 Language FOR MORE CLASSES VISIT www.bus308mentor.com Discussion 1-1/Language Numbers and measurements are the language of business. Organizations look at results in many ways: expenses, quality levels, efficiencies, time, costs, etc. What measures does your department keep track of?

  4. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 1 DQ 2 Probability FOR MORE CLASSES VISIT www.bus308mentor.com Things vary in life – virtually nothing (except physical standards such as the speed of light) we interact with is constant over time. Much of this variation follows somewhat predictable patterns that can be examined using probability. An example of a subjective probability is: “Cops usually do not patrol this road, so I can get away with speeding.” An empirical probability example is: “Each production run has a 5% reject rate.” A classical (or theoretical) probability example is: “This die has six sides, so I should see

For assistance with these calculations, see the Recommended Resources for Week One. Measurement issues. Data, even numerically code variables, can be one of 4 levels – nominal, ordinal, interval, or ratio. It is important to identify which level a variable is, as this impacts the kind of analysis we can do with the data. For example, descriptive statistics such as means can only be done on interval or ratio

  6. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 1 Quiz (New) FOR MORE CLASSES VISIT www.bus308mentor.com 1. Question : In statistical notation, M is to μ as s is to σ. Question 2. Question : A parameter refers to a sample characteristic. Question 3. Question : Data on the city from which members of a board of directors come represent interval data.

Question : Data on the city from which members of a board of directors come represent interval data. 2. Question : Inferential statistics infer the characteristics of samples. 3. Question : The mode is which of the following? 4. Question : The standard error of the mean can be calculated by dividing μ by the square root of

  8. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 2 DQ 1 Hypotheses FOR MORE CLASSES VISIT www.bus308mentor.com Discussion 2-1/Hypotheses What is a hypothesis test? Why do we need to use them to make decisions about relating sample results to the population; why can’t we just make our decisions by the sample value?

  9. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 2 DQ 2 Variation FOR MORE CLASSES VISIT www.bus308mentor.com Variation exists in virtually all parts of our lives. We often see variation in results in what we spend (utility costs each month, food costs, business supplies, etc.). Consider the measures and data you use (in either your personal or job activities). When are differences (between one time period and another, between

Be sure to show all of your work and clearly label all calculations. All statistical calculations will use the

  11. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 2 Quiz (New) FOR MORE CLASSES VISIT www.bus308mentor.com 1. Question : What is the relationship between the power of a statistical test and decision errors? Question 2. Question : The desired sample depends on all of these factors except? Question 3. Question : What question does the z test answer?

  12. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 2 Quiz FOR MORE CLASSES VISIT www.bus308mentor.com 1. Question : How is the sum of squares unlike either the standard deviation or the variance? 2. Question : If sums of squares statistics are calculated for shoppers at three different retail outlets, what statistic will indicate the variability among those at each outlet?

  13. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 3 DQ 1 ANOVA FOR MORE CLASSES VISIT www.bus308mentor.com In many ways, comparing multiple sample means is simply an extension of what we covered last week. Just as we had 3 versions of the t-test (1 sample, 2 sample (with and without equal variance), and paired; we have several versions of ANOVA – single factor, factorial (called 2-factor with replication in Excel), and within-subjects (2-factor without replication in Excel). What examples (professional, personal, social) can

  14. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 3 DQ 2 Effect Size FOR MORE CLASSES VISIT www.bus308mentor.com Several statistical tests have a way to measure effect size. What is this, and when might you want to use it in looking at results from these tests on job related data?

  16. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 4 DQ 1 Confidence Intervals FOR MORE CLASSES VISIT www.bus308mentor.com Discussion 4-1/Confidence Intervals Many people do not “like” or “trust” single point estimates for things they need measured. Looking back at the data examples you have provided in the previous discussion questions on this issue, how might adding confidence intervals help managers accept the results better? Why? Ask a manger in your organization if

BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 4 DQ 2 Chi-Square Tests FOR MORE CLASSES VISIT www.bus308mentor.com Discussion 4-2/Chi-Square Tests Chi-square tests are great to show if distributions differ or if two variables interact in producing outcomes. What are some examples of variables that you might want to check using the chi-square tests? What would these results tell you?

Question : The goodness of fit test null hypothesis states that the sample data does not match an expected distribution. Question 2. Question : Statistical significance in the Chi-square test means the population distribution (expected) is not the source of the sample (observed) data.

How could you verify this? Create a null and alternate hypothesis for one of these issues. What are the managerial implications of a correlation between these variables?

  22. BUS 308 MENTOR Great Stories Here- bus308mentor.com BUS 308 Week 5 DQ 2 Regression FOR MORE CLASSES VISIT www.bus308mentor.com Discussion 5-2/Regression At times we can generate a regression equation to explain outcomes. For example, an employee’s salary can often be explained by their pay grade, appraisal rating, education level, etc. What variables might explain or predict an outcome in your department or life? If you generated a regression equation, how would you interpret it and the residuals from it?
