Week 5 Assignment
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
10|9 11
15|5
20|7
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
