Tau coefficient = (C-D)/(C+D)
= (5-1)/(5+1)
= 4/6
= 0.67 = 67%
Tau coefficient here shows an above average(Slightly Strong) relationship between the ranking of two experts on the sample data

A set of 5 essays (A, B, C, D, E) were ranked by two evaluators.
Both gave the same ranking (D was first, E was second, B was third,
C was fourth, and A was fifth). In the calculation of Spearman rank
correlation, what is the sum of squares of differences of
ranks?

A subjective risk assessment using the method described in ISO31000 was conducted where experts storage site. Experts were consequences and expressed high agreement about relevant causal mechanisms. For one hazard, two assessors gave likelihood and consequence scores and calculated risk scores, summarised below. One expert is an industry-employed scientist and the other is a scientist employed by an environmental non-governmental organisation (NGO) were asked to assess hazards associated with a proposed high-level radioactive waste provided detailed background evidence describing hazard...

Ten new sales representatives for Clark Sprocket and Chain, Inc. were required to attend a training program before being assigned to a regional sales office. At the end of the program, the representatives took a series of tests and the scores were ranked. For example, Arden had the lowest test score and is ranked 1; Arbuckle had the highest test score and is ranked 10. At the end of the first sales year, the representatives’ ranks based on test scores...

URGENT PLEASE HELP
The production of wine is a multibillion-dollar worldwide
industry. In an attempt to develop a model of wine quality as
judged by wine experts, data was collected from red wine variants.
A sample of 20 wines is provided in the accompanying table. Develop
a multiple linear regression model to predict wine quality,
measured on a scale from 0 (very bad) to 10 (excellent) based on
alcohol content (%) and the amount of chlorides. Complete parts a
