INTRODUCTIONThe implication of statistic tools in measuring the operational need of identifying theoperations on which it can be said that there have been fruitful identification of all the statisticalanalysis. There has been determination of appropriate probability theory which will be adequateand helpful as per making suitably decisions. In the present assessment there will be analysisover various supermarkets located at various states. It comprised with the support of descriptiveanalysis as well as various statistical tests. Thus, to identify the outcomes it will be appropriateand adequate as per making suitable changes in the operations. Ascertaining the variousoutcomes through identify values like, mean, standard deviation and several tests.PART 11. Measuring descriptive analysis based on prices at difference supermarketsAscertaining the differences of prices in each supermarkets as per implicating descriptiveanalysis over the data set. Identification of the differences with will be adequate and helpful asper making suitable determination of the facts (Zhang and et.al., 2018). However, the belowstatement will be adequate and helpful as per analysing the differences in the price at varioussupermarkets.Descriptive Statistics:PricenameMean77.5792Mean2.5Standard Error0.94471Standard Error0.10249Median81.415Median2.5Mode60.05Mode1Standard Deviation10.3488Standard Deviation1.12272Sample Variance107.098Sample Variance1.2605Kurtosis-0.7795Kurtosis-1.3667Skewness-0.8941Skewness1.50E-017Range32.34Range3Minimum59.61Minimum1Maximum91.95Maximum4Sum9309.5Sum300Count120Count120Interpretation:On the basis of above listed measurement it can be said that there havebeen huge differences in the prices and supermarket outcomes. Therefore, on the basis of derived1
results on which the average prices of products is 77.58 and standard deviation is of 0.944. Thus,as per ascertaining the outcomes on which it can be said that there are various prices on whichmean prices are of 77.58, median is 81.41 and mode of 60.05. Similarly, in relation withanalysing the supermarket data set. It brings the outcomes like mean value of 2.5, standarddeviation is of 0.102, median is 2.5 and mode is 1. Thus, as per assessing the data set outcomes ithas been analysed here that Tesco is more capable of using the information rather than othersupermarkets. Considering the standard deviation such as 1.122 on which it can be said that themost effective operations is being operated by Tesco in various states.2. Measuring descriptive analysis based or Prices among various statesDetermination of differences between supermarkets and states as per basic staple basketprices. Thus, in relation with this it can be said that there are various outcomes which will beused to have satisfactory analysis over differences in such variables (Chen and et.al., 2017).Therefore, addressing the differences between variables such as supermarket and states theyoperate which will be analysed as per below listed descriptive analysis.Descriptive Statistics:namestateMean2.5Mean2Standard Error0.10249Standard Error0.07485Median2.5Median2Mode1Mode1Standard Deviation1.12272Standard Deviation0.81992Sample Variance1.2605Sample Variance0.67227Kurtosis-1.3667Kurtosis-1.5127Skewness1.50E-017Skewness-4.00E-018Range3Range2Minimum1Minimum1Maximum4Maximum3Sum300Sum240Count120Count120Interpretation:In consideration with the above listed analysing on which it can be saidthat there are differences in the outcomes of supermarkets and the states they operate in. meanvalue of name is 2.5 which brings the outcomes that there are comparatively large numbers ofstores of Tesco and Aeon. Similarly, the mean value of states ascertains as 2 which presents the2
