Q n+1 represents the next state while Q n represents the present state.. References1. Formulae can be entered into the spreadsheet to calculate the sensitivity and specificity as suggested in Table 6. The order of the Truth Table is limited only by the user's available system memory. This might be the Holy Grail of laboratory testing, but diagnostic test performance depends on the population testing and prevalence (how many patients per 100,000 that have disease at any one time). When compared to a reference test or gold standard, for example, a serological test that is positive can either be a true or false positive. We can represent the truth of expressions in a tabular form called “truth tables.” These tables consider all cases and can add great insight into otherwise complicated expressions. • If there are three variables (p, q, and r), you will need 23 or 8 rows. Thus, the top left cell is A1, the next cell to the right is B1, the cell directly below that is B2, and so on. Last accessed May 16, 2010.
