Your action?
• In order to store in the computer, data often coded numerically.
• 1,2,3,4,5
• Do you calculate the mean or variance, even though that Number
is a Name?
• In Excel, if the ʼappearance' is a number, you can calculate it as a number,
even though it is a nominal variable.
• With ordinal variables, such a process seems even more
reasonable.
• But when you are coded using the five-case method, 5, 4, 3, 2, 1,
is 4 double 2? And is there an equal difference of 1 between each
response? To begin with, is 5 to 1 linear?
