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 if …... Observations of this type are on a scale that has a meaningful zero value but also have an equidistant measure (i.e., the difference between 10 and 20 is the same as the difference between 100 and 110). For example, a 10 year-old girl is twice as old as a 5 year-old girl. Since you can measure zero years, time is a ratio-scale variable. Money is another common ratio-scale quantitative measure

- Choosing the Correct Statistical Test Chi-Square Analysis February 20, 2006 Choosing the Correct Statistical Test • Knowing which statistical test to use in order to test the relationship between your independent and dependent variables depends on the ‘type’ of data that you have. Scales of Measurement • A Variable is anything we measure • Remember NOIR. 2 Continuous vs. Discreet
- The best way to determine whether a statistical hypothesis is true would be to examine the entire population. Since that is often impractical, researchers typically examine a random sample from the population. If sample data are not consistent with the statistical hypothesis, the hypothesis is rejected. There are two types of statistical hypotheses. Null hypothesis. The null hypothesis
