Which measure would best summarize the most common lot size in a subdivision?
Correct Answer
D) The mode of the recorded lot sizes
Why this is correct: The mode is the value that appears most frequently. In a subdivision with a standard lot size, the mode identifies that most common, typical dimension. Why the other choices are wrong: "The mean of all the recorded lot sizes" would be skewed by any atypical lots (e.g., corner lots). "The range between smallest and largest" only shows spread, not typicality. "The standard deviation of the lot sizes" measures variability, not the most common size. Exam tip: Use mean for average, median for midpoint, mode for most frequent. For "typical" or "most common," think mode.

An appraiser includes both 'total room count' and 'bedroom count' as independent variables in a regression model estimating single-family home sale prices.

An appraiser runs a regression of sale price on GLA, age, and a binary variable for 'renovated' (1 = yes, 0 = no). The estimated coefficient for 'renovated' is $18,400 with a standard error of $6,200 and a t-statistic of 2.97.
