We provide here additional details on the test statistics and inference procedures used in the paper to assess the strength of identification in regressions based on instrumental variables procedures. These weak instruments test statistics are often reported in empirical applications. However, the inferential implications, particularly for the weak instruments test statistics, are often left un...

The article investigates how 14to 15year-olds build informal conceptions of inferential statistics as they engage in a modelling process and build their own computer simulations with dynamic statistical software. This study proposes four primary phases of informal inferential reasoning for the students in the statistical modeling and simulation process. Findings show shifts in the conceptual st...

Our primary topic for the three-week statistics module in this class will be inferential statistics. Inferential statistics is concerned with making precise quantitative statements about a population, given data on that population, while acknowledging the inherent uncertainty in the data. This uncertainty may be an unavoidable aspect of our data collection or, alternatively, may be purposely in...

In this paper we prove that Neutrosophic Statistics is an extension of the Interval Statistics, since it may deal with all types indeterminacies (with respect to data, inferential procedures, probability distributions, graphical representations, etc.), allows reduction indeterminacy, and uses neutrosophic more general than imprecise classical probabilities, andhas detailed corresponding density...

Soot is a mass of impure particles carbon obtained from incomplete hydrocarbon combustion. an ultrafine air-borne pollutant and enters into the body through ingestion, skin contact inhalation causing devastating effects on blood cells. The aim study was to determine effect soot methaemoglobin oxyhaemoglobin levels individuals resident in both Iwofe, Port Harcourt (exposed subjects) Ihiala, Anam...
