its the standards for quantitative analysis

1. Comparative Case Study Analysis
Definition:
It involves analysis and synthesis of the
similarities, differences and patterns
across two or more cases that share a
common goal

2. A comparative case study
Investigation of data over a period of time
One or more organization
Different groups, within organization

3. It is build on four principles
1. Theoretical sampling
2. Triangulation
3. Analytical pattern-matching logic
4. Analytical Generalization

General Hypothesis

5. • Criteria for selecting individuals/cases determined by research
questions
• These criteria are typically determined in advance of sampling and
remained fixed throughout the process
• Appropriate individuals/cases are identified
• A sample of these is then selected
• A small group of people are selected initially, on the basis or research
relevance

Theoretical Sampling

6. • Difficult to establish, in advance, how many people to be interviewed
• Impossible to say, in advance, when the theoretical saturation point
will be reached
• Larger sample sizes are needed when the quantitative study has broad
scope
• A minimum number of twenty to thirty interviews is recommended
• Great care is needed when making inferences from a purposive sample

7. • The basic assumption of triangulation is counterbalancing
• Strengthen the data with different methods
• Interviewing the same respondent on a particular topic more
than once.

8. • Carefully linking data to propositions
• Precisely defined assignment of subjects and treatment condition.
Example:- Time series pattern
Campbell first showed how the annual number of traffic fatalities rate
over five years.
By state law limiting the speed from 75 to 55 miles per hour.

9. • Two types of generalization
• Statistical generalization
• Analytical generalization
• It helps in testing the validity of the research outcome
