Section 1(1)Explanation on level of measurementsNominal: Nominal variables are those variables which are categorical in nature andelements are not arranged in specific order (Definition of nominal variable, 2017). Ordinal: Ordinal variables are those variables where each and every category is listed inspecific order. Likert scale is commonly used for ordinary variables (Hough and et.al.,2010).Ratio: It is the interval variable and show varied range in which values comes.Measurment of temperature is the example of ratio scale. Binary: It is the variable which have two values which may be 1,0 or yes and no orsuccess and failure etc.(2)Identification of variablesNominal: IMSMETN is one of the nominal variable where different classifications aredone like allow some, allow none and refusal.Ordinal: POLINTR is the ordinal variable where categories are listed as very interested,quite interested, hardly interested and refusal etc.Ratio: ALCKWDY is the ratio varible in the input sheet.Binary:GNDR is the variable that comes in category of gender.

Inter quartile range value is 2 whichindicate that there is very low difference between Q3 and Q1 which means that data pointsrelated to variable are in very small range.(5) Mean and standard deviation of variable satisfaction from lifeDescriptive StatisticsNMeanStd.DeviationHow satisfied with life as a whole400577.092.170Valid N (listwise)40057InterpretationMean value of variable satisfaction from life is 7.09 and STDEV is 2.170 which meansthat people are moderately satisfied from their life. Standard deviation is low which means thatmost of respondents are giving same response on asked question.2 | P a g e
