Is Nistelrooy x 11/9 = Robben????? NoThe Netherlands football team during world cup Nominal Data: Numerical values just "name" the attribute uniquely variables that have two or more categories but which do not have an intrinsic order
2. 2. CAR CODE 1 2 3 4 5 6 7 8 9 10 11 12 Nominal Data: 13 Numerical values just "name" the attribute uniquely 14 variables that have two or more categories but which do not have 15 an intrinsic order
3. 3. The way in which the data can be recordedDichotomous data Example: Mobile Phone or Land Line Ur phone sir!! I have my ownMobile Me too Mobile Mobile
4. 4. Dichotomous data Example: Gender
5. 5. The way in which the data can be recordedOrdered Data: A+ B A Excellent - Poor = ???? A*D = ???? But A is greater than B for sure A>B Excellent > good F Poor < good Have the order. But, Difference is not defined
6. 6. Ordered Data:General General > Colonel RightLieutenantGeneral But,Major General General – Colonel = ?????BrigadierColonelLieutenantColonelMajorCaptainLieutenant
7. 7. The way in which the data can be recordedContinuous data 100 0C - 0 0C = 100 0C 100 0C - 1 0C = 99 0C 100 0C > 90 0C Interval data Operations valid : But, <, >,+. - 100 0C * 4 ≠ 4000C 100 K- 0 K= 100 K 100 K – 1 K = 99 K 100 K > 90 K Ratio data Operations valid : And, <, >,+. -, *, / 100 K * 4 = 400 K
8. 8. Measurement Scales/ Level of Measurement >,<,+,-,/,* >,<,+,- e.g. temperature, as measured in K >,< No absolute zero e.g. temperature, as measured in o F or o C Distances have no meaning e.g. Socioeconomic status cannot quantify or even rank order e.g. gender, race, color, city, etc.
