If the value of r on ratio scaled raw data were 0.87 and the pairs of numbers were converted to ordinal data, and r calculated for the ordinal data, r would equal 0.87.

When converting ratio scaled raw data to ordinal data, the values are ranked rather than using their actual magnitudes. This process can change the relationship between the data points, potentially altering the correlation coefficient (r). Therefore, r calculated for the ordinal data may not equal 0.87, as it was for the ratio scaled raw data.
