Data Scales.

A marketing agency is interested in the buying habits of those who shop online versus those who shop in person. In your discussion post, address each of the following and explain your reasoning as to why you picked the specific scale:

a. A database is created and shoppers are classified as online or in-person shoppers. Such classifications represent data of which scale? Explain your reasoning.

b. Online and in-person shoppers are to be compared on their relative incomes. Income data represent data of which scale? Explain your reasoning.

c. If shoppers are also ranked from the most to the least frequent

ASHFORD BUS 308 Week 1 Quiz

1. 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 the number of values in the distribution.

5. Question : If a certifying agency raises the requirements for real estate agents, what sort of decision error is the agency protecting against?

Imagine a shift manager at a manufacturing plant is gathering data on the number of units workers assemble during two different shifts over 10 different days. If the number of units assembled by each shift varies greatly from day to day, what impact will that have on the likelihood of a significant difference between the two shifts? Explain and support your response.

ASHFORD BUS 308 Week 2 Problem Set

Problem One

Suppose that an automotive parts and accessories chain is experimenting with a new sales promotion. Two similar stores are selected for the experiment. For Store 1, nothing changes. This store constitutes the control group. For Store 2, the treatment group, the promotion is implemented.

Sales in hundreds of dollars over a five-day period are as follows:

Control: 6, 6, 7, 10, 12, 9, 6, 5, 5, 7

Treatment: 2, 5, 2, 4, 7, 1, 2, 3, 4, 5

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?

3. Question : Which is the symbol used for the test statistic in ANOVA?

4. Question : If ANOVA reveals that four different departments have significantly different levels of productivity, what will a post-hoc test indicate?

Use the data in the chart to answer the questions below. The data indicates the number of “sick days” appliance installers take during a three month period, and the number of complaints filed by customers during the same interval. Use the Analysis Toolpak in Excel to perform this simple regression and answer the questions.

a. Is the correlation between number of sick days and number of customer complaints statistically significant?

b. What is the best prediction for the number of complaints that will be registered for an installer who takes five sick days during the period?

ASHFORD BUS 308 Week 5 Final Paper

ASHFORD BUS 308 Week 5 DQ 2 Correlation and Confid

A car dealer is using the number of years customers have owned their vehicles to predict how long it will be before they elect to replace them. The correlation between the two is (the longer they have owned their present vehicles, the more quickly they are expected to replace them). The other relevant data are as follows for 32 customers:

Based on the information above, answer the following questions:

a. How long is the time to expected replacement for a customer who has owned a vehicle 6.5 years?

Assignment Instructions:

A retail store has recently hired you as a consultant to advise on economic conditions. One important indicator that the retail store is concerned about is the unemployment rate. The retail store has found that an increase in the unemployment rate will cause a lack of consumer spending in their stores. Retail stores use the unemployment rate to estimate how much inventory to keep at their stores, which is important in maintaining cost effectiveness. In this consultant role you will apply calculations and research to create a predictive sales report.
