Making Research Decisions
2) Suppose you were preparing two-way tables of percentages for the following pairs of variables. How would you run the percentages?
a) Age and consumption of breakfast cereal.
Here I would use cross tabulation because there are two variables and start by listing age in the left most column. Each row would represent every age concerned, and then the following columns would be the amount or type of cereal consumed depending on what the question desired.
b) Family income and confidence about the family’s future.
Again I would use cross tabulation here, I would list in the left-most columns different income ranges and each row would be realistic of different family incomes. From there, each subsequent column would list a percentage relating whether those in that income bracket felt confident from a scale of 1 to 5.
c) Marital status and sports participation.
Here I would use cross tabulation to list two rows, married and unmarried. Then each column would represent a sport and a percentage of how many people participated in that sport. The last column would be marked as no sports for those that do not play sports at all.
d) Crime rate and unemployment rate.
I would use cross tabulation here and list a number of crime rates or crime rate ranges on the left. Each row would represent the crime rates of that percentage or the range. Then each column would represent a range of unemployment.
From Concept to Practice
7) Use the data in Exhibit 16-5 to construct a stem-and-leaf display.
5|13 15 17 19 21
a) Where do you find the main body of the distribution?
In the zero column or over 0 but less than 5
b) How many values reside outside the inner fence(s)?
3 values – 17,19 and 21
1) Build the management-research question hierarchy.
First, Penton media identified the management dilemma – that ad advertising might not be generating as many leads as in the past. Next, they developed their management question – should they lower advertisement revenues if ads are not generating as much as before? They went on to develop their survey and research questions which included whether or not they made or planned to make purchase inquiries that year, what methods they would prefer to make the inquiries and whether or not they used the internet. Their investigative questions detailed whether or not they had phone, fax, or internet access and their measurement questions included whether the buyer made purchasing decisions based on their methods. This resulted in revealing that buyers were influenced by a greater demand on productivity, the fast pace of business and the cost of production. The management decision in the end concluded that the buyers behavior depended on how immediate their concern was and that the key was giving the buyer the information they wanted quickly. 2) What ethical issues are relevant to this study?
None that I know of – all information is requested not taken, everyone called has an equal chance to participate. 3) Describe the sampling plan. Analyze its strengths and weaknesses. The sample was drawn from domestic subscribers, initially with a small sample, then a sample of 300 and finally with 4,000 Penton employees. Of them, 676 indicated that they were purchase decision makers of their organization. This sample size is large and has potential to be random, however because the pool is so large in the Penton employee category, much of the data may be skewed to however Penton employees may behave. It may not be relevant to worldwide. In addition, because they surveyed subscribers, they are only finding out information from people who already intend to respond and not from a larger sampling which might...
