CPP Research Methods & Evidence-Based Practice 4

Question 1

Which statistical test would a parking researcher use to determine if there is an association between payment method (cash vs. card) and citation rates?

Accepted Answer

Chi-square test of independence

Answer

The chi-square test of independence examines whether two categorical variables are statistically related.

Question 2

A parking demand forecast model uses current land use data to predict future demand. The primary limitation of this approach is:

Accepted Answer

It assumes future land use patterns will mirror current ones

Answer

Land use–based models assume stable patterns; changes in development, behavior, or technology can make projections inaccurate.

Question 3

Which term describes the systematic process of identifying, appraising, and synthesizing all available evidence on a specific parking policy question?

Accepted Answer

Systematic review

Answer

A systematic review follows a predetermined protocol to find and synthesize all relevant studies, minimizing bias.

Question 4

A parking consultant presents a regression analysis showing that adding bike parking reduces car demand by 0.3 spaces per bike space (R²=0.82). What does R² indicate?

Accepted Answer

82% of variance in car demand is explained by the model

Answer

R² (coefficient of determination) represents the proportion of variance in the dependent variable explained by the independent variable(s).

Question 5

An evidence-based parking standard recommends 1.0 spaces per unit for transit-oriented developments. Which type of evidence is LEAST persuasive in supporting this standard?

Accepted Answer

One manager's personal experience at a single property

Answer

A single anecdotal experience has the lowest level of evidence because it lacks replication, statistical rigor, and generalizability.
