CFS Research Methods & Evidence-Based Practice 3

Question 1

Which data collection method is best suited for gathering detailed qualitative insights from experienced floodplain administrators about regulatory challenges?

Accepted Answer

Semi-structured in-depth interviews

Answer

Semi-structured interviews allow experienced practitioners to elaborate on complex regulatory challenges while still guiding the conversation with key topics.

Question 2

When a floodplain researcher reports a p-value of 0.03 for a study on BFE accuracy, what does this indicate?

Accepted Answer

There is a 3% probability of observing the results if the null hypothesis were true

Answer

A p-value represents the probability of obtaining results at least as extreme as observed, assuming the null hypothesis is true.

Question 3

A floodplain management agency wants to use GIS-based spatial analysis to identify areas most vulnerable to repetitive flood losses. Which research design element is this?

Accepted Answer

Data analysis methodology

Answer

Specifying GIS-based spatial analysis as the tool for identifying vulnerable areas defines the data analysis methodology within the research design.

Question 4

In the context of floodplain research, what does 'triangulation' refer to?

Accepted Answer

Using multiple data sources or methods to validate findings

Answer

Triangulation in research involves using multiple data sources, methods, or investigators to cross-validate findings and increase confidence in results.

Question 5

Which type of error occurs when a floodplain researcher incorrectly concludes that a flood mitigation program was effective when it was not?

Accepted Answer

Type I error (false positive)

Answer

A Type I error (false positive) occurs when a researcher rejects a true null hypothesis, concluding an effect exists when it does not.
