Tatom‚ Director of Research at Networks Financial Institute at Indiana State University writes that rising foreclosure filings and excessive personal debt have created the greatest short-term threat to the U.S. economy. This study will examine these and other variables responsible for the rise in foreclosure filings throughout the United

Pilgrim Bank Case September 26‚ 2013 How much do profits vary across customers? Provide statistical support for your answer. Out of a sample of 31‚634 Pilgrim Bank customers‚ from a population of 5 million total‚ and zero missing values‚ profits vary widely. The average customer profitability is $111.50. The minimum value of this data set is -$221 and the maximum is $2071. This describes that there is a very wide range. The median customer profitability is $9 and the standard deviation is $272.84

the DV due to the control variable (concomitant variable or a covariate) is removed. The covariate increases the opportunity to find statistical significance for the factors‚ fixed or random. Simply put‚ the covariate independent variable reduces the variance in the dependent variable that is to be explained by the factors. An example of ANCOVA is testing the effect of computer experience on the use of e-shopping‚ making attitude towards e-shopping as a covariate. The covariate removes its

Siraj Ignorance Response 1 Dr. Veronica Vieland: Measuring Statistical Evidence in Biological Research This lecture really resonated with me because I have taken a yearlong course on thermodynamics and know a bit about statistical thermodynamics. A very important topic that was discussed was the idea of the p value‚ which is a value that is used to make sense of a statistical hypothesis. The significance of the p value on statistical evidence is something that needs to be revaluated due to its

From this case‚ there are two types of errors‚ which the consortium can make. A Type I Error is referred to as a “false positive.” A Type I error would be made when the null hypothesis is rejected when it should be accepted. This error may occur if the consortium defends any lawsuit against them if they are using 6% (6/100) as their surveying result. The results of the sample size of 100 people indicate that the percentage range is from 1.35% to 10.65%. The test results can be higher than 10%‚ but

DS BST 322 Independent Project Background of the study: The data in the dataset comes from a longitudinal study of low-income women in four urban communities. In the original study‚ extensive information was collected in 1999 (Wave 1) and 2001 (Wave 2) from about 4‚000 women. A major purpose of the study was to understand the life trajectories of these women and their children during a period of major changes to social policies affecting poor people in the United States.
