23*5 = 115 So pick any four numbers: integers, fractions, irrational numbers, whatever. Add them together to give a sum S. Let the 5th number be 115 - S Then: sum of all five numbers = (sum of the first four numbers) + (the fifth number) = S + (115 - S) = 115 And the count of numbers = 5 So mean = Sum/Count = 115/5 = 23
In an ordinal scale it is possible to order the categories by some measure. However, it is not possible to know if the difference between the categories is the same or different.For example, clothing items may be classed as extra small (XS), small (S), medium (M), large (L) and extra large (XL). This is an ordinal scale since you know that the sizes increase in the order in which these have been listed. But you do not know if the difference between S and M is the same as the difference between L and XL (or each adjacent pair).Another example is attitude surveys where answers may be "strongly disagree", "disagree", "neither disagree not agree", "agree", "strongly agree".In an ordinal scale it is possible to order the categories by some measure.
