Correlation between Shanghai and Times ranking systems. Data are considered for the top 500 universities in the Shanghai and Times systems. Cross marks denote universities ranked outside illustrated rank positions in either system. Note that for Shanghai it is common for several universities to have the same aggregate score and thus share the same rank (the median value of the span of ranks involved).
