Free CAE Mass Appraisal and Statistical Analysis Questions and Answers — Questions and Answers
Question 1: What is the primary purpose of mass appraisal in property assessment?
- To appraise only high-value homes
- To manually assess each property individually
- To automate and standardize property valuations (Correct answer)
- To enforce building codes
Correct answer: To automate and standardize property valuations
Mass appraisal involves valuing a group of properties as of a given date using standardized procedures and statistical testing for equity and uniformity.
Question 2: Which statistical measure is most commonly used to determine the accuracy of a mass appraisal model?
- Mean absolute deviation
- Median sale price
- Coefficient of dispersion (COD) (Correct answer)
- Standard score
Correct answer: Coefficient of dispersion (COD)
The coefficient of dispersion (COD) is used to measure the uniformity of assessments in mass appraisal.
Question 3: Which variable is typically considered in a mass appraisal regression model?
- Homeowner’s income
- Property owner's age
- Number of pets
- Living area in square feet (Correct answer)
Correct answer: Living area in square feet
Living area (square footage) is a significant factor in valuation models used in mass appraisal.
Question 4: In mass appraisal, what is the significance of stratification?
- To simplify zoning codes
- To reduce tax rates
- To group similar properties for analysis (Correct answer)
- To prioritize commercial assessments
Correct answer: To group similar properties for analysis
Stratification groups similar properties together to improve model accuracy and consistency within valuation models.
Question 5: What is the purpose of calibration in a mass appraisal model?
- To reduce the number of comparable sales
- To set tax rates
- To adjust the model to reflect market data (Correct answer)
- To remove non-compliant properties
Correct answer: To adjust the model to reflect market data
Calibration fine-tunes model coefficients to align estimated values with actual market values for accuracy.
Question 6: Which of the following best defines 'model specification' in mass appraisal?
- Number of appraisers on staff
- Amount of taxes owed
- Defining variables and equations used in the model (Correct answer)
- Determining property ownership
Correct answer: Defining variables and equations used in the model
Model specification defines the functional form and variables included in a mass appraisal model to estimate property values accurately.
