... For example, a researcher wants to study whether a new drug is better than an old drug to reduce anxiety symptoms. If we gave the old drug to the subjects and assessed them and then gave the new drug, there might be carry-over effects from the old drug still. Thus, we might want to use two different ...

... The "t value" or the "F value" obtained in a particular statistical analysis is compared to values in a table, and a probability value, or p-value determined. The p-value tells you how likely it is that the two (or more) samples you have were drawn from the same population. Another way of saying th ...
