IAAO COURSE 300 FULL PRACTICE REVIEW
2026 TESTED QUESTIONS
◉ Quality. Answer: ____________________ relates to how accurately
recorded information, used to estimate values reflects current status
of the property.
◉ Discrete. Answer: Qualitative items that have three or more
predefined values e.g. (topography, level, rolling or steep) are known
as ________________ data.
◉ Data Inventory. Answer: A _______________ manual should explain
how to collect and code data thus ensuring greater uniformity
among appraisers.
◉ Consistency. Answer: A __________________ edit makes certain that
the number of bedrooms does not exceed the total room count or
the square footage of the basement is not greater than the square
footage of the finished area.
◉ Subjective. Answer: _________________ data are items where the
proper value is a matter of judgment, such as construction, class,
condition, etc.
,◉ Quantity. Answer: ________________ relates to the completeness of
the available data or what must be collected to capture local market
influences.
◉ Classroom, Field. Answer: Data collectors should have both
________________ and _______________ training.
◉ Array. Answer: The listing of data in order of magnitude (either
ascending or descending) is termed a/an _______________.
◉ Histogram. Answer: The charting of a frequency distribution using
a _______________ illustrates the extent to which sales ratios are in a
normal (bell shaped) distribution.
◉ Range, Quartiles, Percentiles, Standard Deviation, Coefficient of
Variation. Answer: List five common measures of dispersion.
◉ Cross-Tabulations. Answer: ____________________ show the
distribution of values for two binary or discrete variables.
◉ Scatter Diagrams. Answer: __________________ show the relationship
between two quantitative variables with the dependent variable
placed on the vertical axis and the independent variable placed on
the horizontal axis.
, ◉ Polygon. Answer: A _____________________ can be used to show
several variables simultaneously, or the same variable for different
strata.
◉ Breakdowns. Answer: _________________ compare statistics (usually
measures of central tendency) by strata, for example, average sale
price by neighborhood.
◉ Contingency Tables. Answer: _____________________ show summary
statistics for a dependent variable by combinations of two
independent variables, for example, average sale price per square
foot by construction grade and neighborhood.
◉ Standard Deviation. Answer: Interpretation of the
__________________________ as a measure of spread or dispersion
depends on the data being "normally distributed" (approximating a
bell-shaped curve).
◉ Coefficient of Variation. Answer: The __________________________
expresses the standard deviation as a percentage of the mean.
◉ Outliers and Extremes. Answer: Cases beyond the whiskers in box
plots are ____________ and _______________________.
