Simple random sample

between variables should be done in the model to eliminate the multicollinearity effect. Based on the results of F and Hausman test, a fixed effects model is selected from three basic estimation techniques for panel data, including simple cross-section, fixed and random effects approaches. Finally, t-statistic and F-statistic show the significance level of individual variable and overall…

typically called normal life. Failures during infant mortality are highly undesirable and are always caused by defects and mistakes like: material defects, design mistakes, manufacturing defects, etc. Normal life failures are normally considered to be random cases of "stress exceeding designed strength" due to abnormal operating conditions. Wear-out is a fact of life due to fatigue or depreciation of materials. After useful life period most of the equipments fails which is normal and acceptable…

impacts of CSA and whether there is a direct link between it and the effects that occur later in life. Although much of the earlier research in this area used cross-sectional studies with convenience or clinical samples, recent studies have progressively used large random community samples producing more reliable findings. The questions being reviewed in this literature review are ‘what are the long term impacts of child sexual abuse?’, and if so do intervening characteristics influence them to…

This study is a cross-sectional evaluation of random digit-dial telephone surveys to identify patterns of eating away from home and attitude toward it. Participants included 530. Attitude toward Fast-Food was measured using an 11-item, 4-dimensional scale: perceived convenience of Fast-Food (alfa =…

As you walk down the street if you are not already doing this yourself, you see everybody staring down at your phone or ipad. Americans walk around with their heads tilted towards the ground staring at the little rectangle in their hands. It is almost like the little rectangle controls their minds, giving them directions on how to live their lives, almost as if they can’t live without it. I believe technology today is creating a negative effect on society. Due to the increasing dependence on…

of developing dementia, or cognitive functions. He probably had a field day when it was discovered that the clinical trials cited on Lumosity’s website that demonstrated positive results from the program were found to have used an extremely small sample size—a major faux pas in scientifically sound research. Additionally, he would have taken issue with the methodology sections’ unclear explanation of how control groups were handled in the clinical trials. I can only imagine that the idea of a…

Lee’s saw push & pull factor concepts in 1966 . He developed a “general schema into which a variety of spatial movements can be placed” (Lee, 1966:49). He also tried to figure out a number of conclusions with regard to the factors in the act of migration, the volume of migration, the development of streams and counter streams, and the characteristics of migrants. With regard to the factors in the act of migration he divided into “push” factors (factors associated with the area of origin),…

This is where you [divide] the population into subpopulations (strata) on the basis of some supplementary information. From each stratum, draw a random sample in proportion to stata sizes; this ensures representativeness (Mahboob, 2015, lecture 4). In my case, I will be dividing tourists of Niagara Region into winery tourists since I am focusing on winery tourism. In my qualitative research, I will be…

The difference between nature and nurture is that nature is the idea that behavior is effected by your chemical and gene make up while nurture is the idea that you are a blank slate and your behavior is distinguished by experiments. They both effect behavior is what was discovered. * Dualism is supported by cognitive psychologists such as George A. Miller and Sigmund Freud * Rene Descartes dealt with Monism vs. Dualism & Interactive Dualism * Monism is the belief that the mind…

‘Time’ represents EMG T2-T1 values. The rows directly below this represent the 2 different exercise sessions (1= Pre-CHO, 2= Post-CHO). For each exercise session, the standard deviations are shown, the sample size (i.e., N), and the significance. Each of the participants (N=9) performed both tests. The asterisk in the foot note provides criteria for significance (Sig<.05). The column ‘Sig’, determines whether or not the difference between the mean times…
