**CHAPTER 3 COMMONLY USED STATISTICAL TERMS**

Standardized test statistics are a way for you to compare your results to a “normal” population. Z-scores and t-scores are very similar, although the t-distribution is …... mathematical statistics course, stressing the conditions under which one could use each test, the types of hypotheses that can be tested by each test, and the appropriate way to use each test. In

**mathematical statistics How to determine a threshold**

Test Statistics and P-Values When you run a hypothesis test , you’ll use a distribution like a t-distribution or normal distribution . These have a known area, and enable to you to calculate a probability value ( p-value ) that will tell you if your results are due to chance, or …... From here we know we should use a test for trend, or a Mann-Whitney U test (with correction for ties). Note, however, if some people share a general practitioner and others do not, then the data are not independent and a more sophisticated analysis is called for.

**One-way ANOVA Laerd Statistics**

The primary parameters used are the mean (or average) and the standard deviation (see Fig. 6-2) and the main tools the F-test, the t-test, and regression and correlation analysis. Fig. 6-2. A Gaussian or normal distribution.... Test method. Use the one-sample t-test to determine whether the hypothesized mean differs significantly from the observed sample mean. Analyze Sample Data . Using sample data, conduct a one-sample t-test. This involves finding the standard error, degrees of freedom, test statistic, and the P-value associated with the test statistic.

- Statistics Calculator will automatically use Yate's correction for two-by-two tables when the expected frequency of any cell is less than 5 or the total N is less than 50. If there is only one column or one row (a one-way chi-square test), the degrees of freedom is the number of cells minus one.
