Quizplus · Accepted Answer

Variable respecification involves the creation of new variables or the modification of existing variables to enhance their usefulness in statistical analysis. This process can include recoding values, computing new variables through mathematical operations, and transforming variables to improve their distributional properties. B) Scale transformation involves changing the scale of measurement for a variable, such as converting measurements from centimeters to inches. C) Weighting involves adjusting the importance of different observations in the analysis based on their relative weights or probabilities. D) Standardization involves converting variables to z-scores to facilitate comparisons across variables with different units or scales of measurement.
