Measurement, 2013
Abstract In the past, ratio scales have been a highly controversial issue between physicists and psychologists as regards the need for an empirical addition operation in order to attain them. This aspect is critical since such an operation is often unavailable in psychophysical experiments, as it is in physics, due to its intensive properties.

The Arithmetic Teacher, 1977
My mathematics class was a high ability, sixth-grade group who understood ratio and scale, but, at the start of the project described here, needed practical exercises in using these skills. The need for practice in applying the concepts of ratio and scale suggested the use of architectural floor plans.

Scale ratio ICP for 3D point clouds with different scales
2013 IEEE International Conference on Image Processing, 2013In this paper we propose a method for matching the scales of 3D point clouds. 3D point sets of the same scene obtained by 3D reconstruction techniques usually differ in scale. To match scales, we estimate the ratio of scales of two given 3D point clouds.

A Proposed Method for Absolute Ratio Scaling
Psychometrika, 1950A method of ratio scaling is described for treating comparative judgments of paired stimuli. A method of comparative judgment developed by Metfessel is employed. Formulas for scale values and the solution of a sample problem are provided. The method is designed to provide internal-consistency checks on the scale values.

A Ratio Scale Measurement of Conformity
Educational and Psychological Measurement, 1989Since the seminal work on conformity, there has been a steady stream of research attempting to isolate individual and situational variables that influence its expression. Most previous studies have employed either proportions of participants showing conformity or have used Likert scales to measure changes in conformity as a function of different ...

A “Halo”-Model for Multidimensional Ratio Scaling
Psychometrika, 1970A model for direct multidimensional ratio scaling is presented, based on the concepts “common” and “difference” of the “halos” of two percepts. Measures of halos and their differences are proportional to lengths of corresponding percept vectors and their distance in subjective space.

Scale ratios, statistical symmetries and intermittency
Europhysics Letters (EPL), 1998Existence (or lack) of preferred scale has largely been used as a useful guide to investigate statistics of stochastic extended systems. In particular, widespread use of power laws in literature actually comes from the fact that these are the only single scale functions pertaining to systems relying on no preferred scale.

A photographic method of changing the ratio of ordinate‐scale to abscissa‐scale
Terrestrial Magnetism and Atmospheric Electricity, 1931This method is proposed for the purpose of reproducing magnetograms or other continuous photographic records made at different observatories on the same scales as regards both time and value of magnetic or other recorded element with all the minutiae of detail.
