Using the accompanying table, which gives values for a hypothetical violent crime index, shift the base from 1982 to 2002 and recalculate values for each of the years in the table.
Year | Index of Violent Crime | Index of Violent Crime |
---|---|---|
(1982 = 100) | (2002 = 100) | |
1982 | 100.0 | _____ |
1986 | 104.2 | _____ |
1990 | 116.8 | _____ |
1998 | 132.5 | 100.0 |
2002 | 140.0 | _____ |
2006 | 138.6(est) | _____ |
Assume that we wish to construct an index of community integration involving the following indicators:
In this index, indicators a, b, and c are to be weighted equally, d is to be given triple weight, and e is to be given double weight. A person receives a 1 if he or she answers yes to the question and a 0 otherwise.
Write a set of five items to measure a concept of your choice. These items should be such that they are likely to constitute a Guttman scale. In other words, the items should be increasingly difficult or restrictive so that a respondent who “passes” an item will also be very likely to “pass” all scale items that are “easier.”
What concept are you trying to measure?
List the items in order of increasing difficulty or restrictiveness.
Devise at least six items that could be used to measure the concept of “job satisfaction.” Show how the responses to these items would be scored and how they could be combined into an index.
Write 10 items that could be used in a Likert scale to measure attitudes toward the concept of regional government (as opposed to traditional city and county government). Be sure the items are clear, grammatically correct, and appear to measure the same dimension. Provide an appropriate set of 5-point alternatives for each question.
In a study of political participation, you ask a sample of 100 persons the following four questions:
Item 1: Have you ever run for public office?
Item 2: In the past year have you attended political rallies or meetings?
Item 3: In the most recent election did you ever persuade others to vote a certain way?
Item 4: Did you vote in the last election?
Responses to these items produced the following results:
Item 1 | Item 2 | Item 3 | Item 4 | Number of Respondents |
---|---|---|---|---|
Yes | Yes | Yes | Yes | 2 |
No | Yes | Yes | Yes | 10 |
No | No | Yes | Yes | 15 |
No | No | No | Yes | 25 |
No | No | No | No | 40 |
No | Yes | No | No | 4 |
No | Yes | No | Yes | 2 |
Yes | No | Yes | Yes | 2 |
