PROCEDURES FOR SCRAMBLING SENSITIVE QUANTITATIVE VARIABLES: AN UPDATED REVIEW.

In this document is presented a review of the current literature on randomized responses for quantitative variables. The review is chronological ordered considering its origin, Warner (1965), up to recent proposals. The techniques are classified and some are selected for classification. A study, using real data is developed using data that may be considered as sensitive, evaluating the accuracy and efficiency of the best quantitative randomized response techniques.
