Document Summary
Scales of measurmeent properties of scales of measurement. Talking about rank numerically of some phenomenon. take out the feelings. Difference: meaningful difference dont know where exactly someone is relative to 2nd place holder . lacking meaningful differnecei f just put 1st sencond third. then introduce score 0-100 %. 40% at rodeoing is 60% different . know exactly how different and where they are positioned relative to each other. Ratio: concept of true zero. true zero: absence of phenomenon. zero means nothing is there. Kelvin sclae 0 means absence of temperature. in that context, there is a ture zero for kelvin scale rating scale on feelings 1 2 3 4 5 0 doesnt mean absence of feelings. Then decide which scale: is that variable discrete or continuous? how many siblings? can only have whole siblings discrete. give score 0-100% can give 95. 5, decimals continous.
