A Comparative Study between Ridit and Modified Ridit Analysis

Abstract

This paper compares ridit analysis with modified ridit analysis. The comparison was then illustrated with an example. It was observed from the example at least, that when the sample sizes of the two samples being compared are too disparate, a more reliable conclusion using the Bross ridit analysis is likely to be reached only when the group with the larger sample size is used as the reference group. Otherwise Bross ridit analysis would lead to conflicting conclusions, depending on which group is used as the reference group. Modified ridit analysis treats the groups being studied as samples drawn from some larger populations in which the variances or standard deviations as well as the results obtained are the same no matter which sample is used as the reference group. The modified procedure is therefore preferable to ridit analysis especially in cases where the groups being compared are samples from some populations.

Antecedents of mobile advertising value: a precedence analysis using the hybrid RIDIT-GRA approach

“…Appendix shows the measurement items for the research constructs. Bross (1958) was the first to propose the RIDIT analysis as a technique that does not attempt to quantify categories but rather works with their natural order (Uwawunkonye and Anaene, 2013). He introduced this technique as a 'missing link' or interface between categorical data analysis and non-parametric statistical analysis.…”

“…RIDIT analysis represents a mechanism of likelihood transformations based on an observed distribution. This is a distribution-free technique because it does not make any assumptions about normality or any alternate form of the distribution under study (Fleiss et al , 2013; Uwawunkonye and Anaene, 2013). It is essentially a weight allotted to a response group that reflects the probability of its appearance in the standard distribution.…”

“…Following such a ranking, a modified ridit transformation [ 20 , 21 ] was distinctly applied to the family structure (model A) and to the school region (model B), and for each survey year, in order to obtain a ranking score x i between 0 and 1. The family and regional ranks x i were determined as follows for each family and regional category and for each survey year: where c i is the fraction of the population in the class i or lower ( c 0 = 0 and c i = 1) [ 21 ].…”

Precedence analysis of customer engagement dimensions for tourism destinations: an evidence-based modeling using RIDIT-GRA approach

“…RIDIT analysis RIDIT analysis was conceptualized by Bross (1958) as a technique to address the missing link between categorical data and non-parametric statistical analysis. RIDIT analysis analyzes the data with their natural order rather than quantifying categories (Uwawunkonye and Anaene, 2013). It specifically observes the likelihood transformation of the data of an observed distribution (Sharma et al, 2022).…”
