Fig. 25 and Fig. 26 depict the vote shares of peer and employer’s perception for various categories of Institutions. It is

extreme, all other remaining subject categories, i.e. Law, Medical and Architecture continued with the trend of weak

7.6. Rank Order Correlations across Parameters

Table 27 given below provides value of Spearman’s Rank Order Correlation Coefficient between ranks of institutions
based on its total score with that of its rank based on research performance in various categories and subject domains.

As mentioned before, data for research performance is taken from third-party independent sources, namely Web of
Science. Fig 27 to Fig. 32 depict the mean of the scatter plots of corresponding scores along the two axes for various
categories and subject domains. A very strong and positive correlation can be noticed for each discipline except for
colleges. The strong correlation between ranking by research performance based on data from third-party
independent sources and overall ranking vouch for authenticity of data collected from institutions.
