1. Provide the briefest and most relevant explanation which supports or rejects each of the following; standalone support/reject answers will be ignored. 1.1 Given statistical computations using the same large sample, one computation based on grouped (weighted) data and the other computation based on ungrouped (unweighted) data, both computations will yield identical results, excluding possible rounding errors. 1.2 Given two representative random samples from the same population, both samples large but one twice the size of the other, the two samples' statistics will significantly differ 1.3 The four data levels of measurement types have the same mathematical properties 1.4 The three principal data collection methods are essentially equivalent and can be substituted for one another 1.5 In a large, well designed random survey of Facebook users, 80% said they would not vote for former president Trump; therefore, the online social media community will not vote for Trump 1.6 If the sample's standard deviation equals the IQR, that raises questions about the validity of the sample and/or the data collection methodology
