Probability distribution

The article, “Standard Error of Measurement” by Leo M. Harvill from East Tennessee State University, provided a general introduction of Standard Error of Measurement (SEM). First, it introduced the basic concepts of test reliability. An obtained score or a raw score refers to the number of points obtained by an examinee. The obtained score could be influenced by several factors such as the ambiguity of test items, the fatigue of the examinee, and these factors make the obtained score unlikely to…

the form of graphs and charts, quality in the form of frequency of errors, and in the media as survey results and weather forecasts. Some folks may be nervous when they hear the word statistics; however, they are most likely using statistics and probability nearly every day of their life and not even notice it. Beltway Shoe Company is featured in this exercise reviewing the results of their Western and Eastern region shoe sales. The data is broken out by Original Price, Sale Price, and Number…

B - The value of (Ao) in the North Western part of Nile Delta and Alexandria is the same in most points and varied from 5 to 7 and…

High EQ types will consistently score between 10-12 almost every time. A more formal term for what I have called the inner you is what the EQ-i (or Emotional Quotient-Inventory) calls the "Intrapersonal EQ Scale." "Intra" means "inside," "inner."

. 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…
