This endeavor employs a methodology that requires, in part, the use of an assigned rate that is based on the customer's scores, which indicate the customer's credit worthiness.John R. GerlachMaryEllen Unruh
Pearson's r as a measure of the linear relationship between two quantitative variables. In a sample, we use the symbol r. In a population, we use the Greek letter ρ ("rho"). Pearson's r can easily be computed using statistical software. ...
3.2. Quantitative analyses In what follows, we will present the quantitative analyses related to student teachers’ grammatical reasoning. We will start by providing some descriptive statistics and a few basic analyses (3.2.1), continue with a section on TGU scores (3.2.2) and student teachers’...
All quantitative enzyme assays were expressed as mean ± SD from three independent experiments. X-ray crystallography XacGH43_1 at 28 mg mL−1 (0.7 mM) crystallized by vapor diffusion method in sitting and hanging drops containing 0.2 M ammonium sulfate, 30% (w.v−1) ...
One way to bypass this problem is to remove the structural zeroes from the table and implement a test on the remaining cells which incorporate the randomness in the sampling zeros; the resulting test is a test of quasi-independence of the two categorical variables. This test is based only on...
What variables should you measure in an experiment? Independent or dependent variables? How are qualitative and quantitative observations the same? How are they different? How are CH50 assay analyzed in the scientific literature? Why is random assignment in a clinical trial an effective way to a...
Design Considerations for a Two-Sample t-Test The characteristics of the t-tests in the above examples are the following: A Two-Sample t-Test Compares Means In an experiment designed to use the two-sample t-test, you want to compare means from a quantitative variable such as height, ...

Their samples were processed with the use of a quantitative method of isolation5. This experiment showed that dictyostelids are affected by environmental factors, especially moisture6. It is now known that there are a number of factors which can affect the distribution and abundance of dictyost...
Correlation in statistics is a quantitative measure of the strength of the relationship between two random variables. Different methods of calculating the correlation are available such as Pearson's Product Moment Correlation or the Spearman'...
