What is the reference point of a non-owner of a mug? Give both r1 and r2. Solve for the “buying price”, the maximum price at which a non-owner is willing to buy a mug.

2. This question asks you to think about the mug experiments discussed in class in terms of actual utility functions. Let two dimensions of choice be mugs and money, with mugs being dimension 1 and money being dimension 2. Denote outcomes in mugs and moneyby c1 and c2, respectively, and reference points in the two […]

Discuss the importance of the Measures of Center and the Measures of Variation.

Introduce your scenario and data set. Provide a brief overview of the scenario you are given above and the data set that you will be analyzing. Classify the variables in your data set. Which variables are quantitative/qualitative? Which variables are discrete/continuous? Describe the level of measurement for each variable included in your data set. Discuss […]

What role do extraneous variables play in our interpretation of data?

What role do extraneous variables play in our interpretation of data? Provide examples where the statistical results could be influenced by other factors. For example, a group may spend 50% less on hair care products which could indicate they have less hair or it could mean they have poor personal hygiene.

Calculate BMI from the HEIGHT and WEIGHT variables (BMI=Weight/Height2). Examine and comment on the distribution of this new variable.

1.Read the Excel file FEV1.xls into SPSS. Label the variables (see the key table above) andadd value labels where necessary. Alter the number of decimal places displayed to suit each of the variables. Check that all the variables are set up as the appropriate type (measure), i.e. Scale, Nominal or Ordinal. Save the file as […]

What questions do you have for your instructor that might impact your final project? Do you feel that you understand the project? Are you on track to hand it in on time?

In this journal, you have the opportunity to discuss privately with your instructor the status of your final project. At this point, you have completed all of your milestones and have received feedback, and you should be preparing to hand in your final project in Module Nine. What questions do you have for your instructor […]

What statistical questions are you asking? Why would you want to predict the value of Y? What if you wanted to predict a value of Y that’s beyond the highest value of X (for example if X is time and you want to forecast Y in the future)?

Option 1: Think of a problem dealing with two possibly related variables (Y and X) that you may be interested in. Share your problem and discuss why a regression analysis could be appropriate for this problem. Specifically, what statistical questions are you asking? Why would you want to predict the value of Y? What if […]
