Selecting Programs
7Surfacing And Identifying Problems
- Use data to surface potential problems
- Use values and discussion to weigh the relative
importance of identified Problems - Prioritize a set of problems for further
investigation
8Example Problems
- Teen Pregnancy
- Sexually Transmitted Diseases
- Child Neglect
- School Drop Out
9Modeling Problem Relationships
- Use data to uncover the structure of the
Problem(s) considering possible causes,
inter-relationships and changes over time - Use existing theory and research to further
explore the structure of the problem - Use values to explore agreement with formal and
informal sources of information - Negotiate and develop a model of the Problems
showing causes and associations
10Modeling Tools
11A Problem Model
12Selecting Programs
- Use research on promising programs to explore the
various programs that may be responsive to the
identified problems and the developed model - Use values to determine which of the potentially
responsive programs may work best in the
community - Choose one or more promising programs
13Choosing a Program
14Surfacing and IdentifyingProblem(s)
15Surfacing and IdentifyingProblem(s)
- Purpose
- To teach participants basic data interpretation
skill and to use these skills with a data set to
derive a prioritized set of problems
16What Do Numbers Say?
17What Do Numbers Say?
18Why Are Numbers Limited?
- Their Meaning is Often Only Understood In
Relation to Population Figures - Because of This, Numbers May Distort Our
Understanding of Problems
19Instead, Use Rates
A Rate is a Simple Calculation That 1.
Relates a Number to a Relevant Population
Figure 2. And Then, Multiplies it by a Large
Number to Make it More Interpretable
20Why Do We Do This?
Because Rates Allow Us To Make Numeric
Comparisons Between Places and/or Over Time Even
When Population Figures Are Different!
21How Do We Calculate a Rate?
We Need Three Pieces of Information The Number
(e.g., Aggravated Assaults) The Population
Figure The Per Number We Want to Use To Make
the Rate Easy To Interpret
22How Do We Calculate a Rate?
The Simple Formula is Number Per
Number Population
23Calculating Rates
Choose 10,000 as the Per Figure
24Calculating Rates
8 Assaults Per 10,000
25Calculating Rates
26So, How Do Our Numbers and Rates Look Different?

28Are Rates All You Need To Know?
Rate Per 10,000
29Are Rates All You Need To Know?
Rate Per 10,000
30Modeling ProblemRelationships
- Graphic Models and
- Analytic Tools
31Modeling ProblemRelationships
- Purpose
- To teach participants more advanced
interpretation skill and to use these to create
and model their understanding of one or more
problems
