• Weighted Coefficient of DispersionThe coefficient of dispersion when the absolute differences between individual assessment ratios and the measure of central tendency (for example, the median ratio) are weighted on the basis of the sale price.
• Weighted Coefficient of VariationThe coefficient of variation when the squared differences between individual assessment ratios and the arithmetic mean ratio are weighted on the basis of the sale price.

• Weighted Mean; Weighted AverageAn average in which each value is adjusted by a factor reflecting its relative importance in the whole before the values are summed and divided by their number.
• Written Estimate of Market ValueFor certain transactions (e.g., those that are below the de minimis), the NCUA allows credit unions under its jurisdiction to obtain a written estimate of market value in lieu of an appraisal. According to the agency’s regulations, individuals who prepare ‘written estimates of market value’ must be sufficiently qualified; however, the agency has also opined, “an AVM can be used to meet the valuation requirement in conjunction with review by a loan officer or an individual with knowledge, training, and experience in the real estate market where the loan is being made.”
