You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

This is a commonly used statistical procedure by many graduate students and faculty. Because the Chi Square relies on frequency data, its value lays in the . The standardized residuals are the raw residuals (or the difference between the observed counts and expected counts), divided by the square root of the expected counts. Interpretation You can compare the standardized residuals in the output table to see which category of variables have the largest difference between the expected counts and the actual counts relative to size, and seem to be todocostadelestecomar.somee.comg: dissertation.

The Chi-Square Test has two major fields of application: 1) goodness of fit test and 2) test of independence. Firstly, the Chi-Square Test can test whether the distribution of a variable in a sample approximates an. An alternative residual is based on the deviance or likelihood ratio chi-squared statistic. The deviance residual is defined as \[\tag{}d_i = \sqrt{2 [ y_i \log(\frac{y_i}{\hat{\mu}_i}) + (n_i-y_i) \log(\frac{n_i-y_i}{n_i-\hat{\mu}_i}) ]},\] with the same sign as the raw residual \(y_i-\hat{y}_i \).Missing: dissertation.
