With interval-ratio variable

It is the difference between the maximum and minimum values in the distribution.

Example

ISSP, 2006, Hungary. Income by party preference.

 Party preference Mean Minimum Maximum Range MDF 224.050.00 43.000 500.000 457.000 SZDSZ 133.392.86 24.000 500.000 476.000 FKGP 57.166.67 40.000 70.000 30.000 MSZP 123.963.76 10.000 500.000 490.000 FIDESZ 125.898.94 15.000 500.000 485.000 Munkáspárt 75.400.00 37.400 125.000 87.600 MIÉP 165.433.50 23.000 500.000 477.000 Other 159.100.00 54.000 500.000 446.000 Uncertain 148.636.12 2.000 500.000 498.000 Total 134.243.96 2.000 500.000 498.000

Check the computation of the range by comparing the maximum and minimum values.

Interpret the differences in ranges.

Compare the amount of variability in different group of supporters.

In Section The mean, MDF-supporters turned out to be the highest mean income group. How much variability does this group show comparing to the others?

Why is the range not appropriate for nominal or ordinal variables?
