. From table 6.7, it is observed that the Chi-square statistic is 104.089. Since P value is less than 0.01, the null hypothesis is rejected at 1 percent level of significance. Hence, concluded that there is association between stages at diagnosed as a kidney disease and cost factors in thousands of kidney patients. Based on the row percentage, Stage diagnosed as a kidney patients upto stage III, 6.0 patients are below 50000, 54.0% are 50000-100000, 26.0% are 100000-500000, 6.0% are…

What statistics were used to describe the length of labor in this study? Were these appropriate? The SD of the experimental group was 7.78 hours with a mean of 14.63 and was measured in 30 of 32 subjects. The SD of the control group was 7.2 hours with the mean being 12.79 hours, measured in 33 of 35 subjects. Based on the statistical methods to obtain the means, these number look right to me although 12 to 14 hours of labor for an average woman in today’s world is often long thus I would…

In our book Naked Statistics by Charles Wheelan we read some chapters in where we use stats in three different ways to get close to the answer without using all the data. We see how indepednt variables and dependent variables relate to each other and how we can get close to seeing how close they relate without using the full data. Correlation is a form of statistics in…

Darrell Huff masterfully writes How to Lie With Statistics which covers many of the statistic gathering and displaying methods used today, from carefully picked averages to well chosen samples. He does not simply discuss these methods, however. He spectacularly demonstrates how companies, colleges, and quite often media sources use these tools to manipulate data into their favor. While it may appear to be fairly outdated to the casual reader, Darrell Huff's book still applies today, over…

Sabermetrics is formally known as the empirical analysis of baseball, especially baseball statistics that measure in-game activity.

Why do Christians frequently abuse statistics? Is it to provoke shame in Christians for their “laziness”? Its main intent is to motivate Christ followers to make more disciples. Religious leaders and organizations habitually use descriptive statistics in misrepresenting and sometimes absolutely outlandish ways, usually to get attention and sound alarms, which are usually false alarms.
