Analysis of Newspaper Research ReportStatistics, the mathematical ?science of perk up uping, organizing, and interpreting information? (Bennett, Briggs & Triola, 2003, p. 2) changed the world by establishing a method for researchers to collect and interpret statistical data. The orderly battle array and interpretation of data provides a basis for decision reservation based on fact rather than on whim (University of Phoenix, 2007). The goal of researchers is to pack a state, ?the complete set of pile or things universe studied? (Bennett, et al., 2003, p. 3) and to analyze characteristics, known as population parameters, particular(a) to the group, in order to assess the rigor of what is believed to be true. ?statistical science provides methods that enable researchers to determine how easily a try on statistic estimates a population parameter? (Bennett, et al., 2003, p. 5). illative statistics spends random sampling of the general population to draw conclusions. Surveys or opinion canvas are a method to use assay statistical estimates to study population parameters. An important barb for strengthening the validity of the research is application of a bank of geological fault. The margin of error is added or subtracted to the sample statistic to happen the ? hunt or interval, of set likely to contain the population parameter? (Bennett, et al, 2003, p. 5).
Margin errors for well conducted surveys or tops range from 10% for a sample size of 100 to 1% for a sample of 10,000 (Bennett, et al, 2003). Dr. Matthew M. Davis of the University of mile recently released the results of an internet poll which surveyed 2,060 adults. The purpose of the sur vey was to treasure the perception of paren! ts regarding the weights of their children. The adults self report the height and weight measurements of their children and were questioned if they considered their children to be over, If you want to get a full essay, order it on our website: OrderEssay.net
