High Quality Content by WIKIPEDIA articles! The cumulative frequencies are plotted, and PSM advocates claim interpretive qualities exist for any intersecting of the cumulative frequencies for each of the four price categories. Note that the standard method requires that two of the four cumulative frequencies must be inverted in order to have the possibility of four intersecting points. Conventional practice inverts the cumulative frequencies for "too cheap" and "cheap". The general explanation of intersecting cumulative frequencies varies. A common description of the intersections is that the crossing of "too cheap" and "expensive" can be the lower bound of an acceptable price range. Some describe this as the "point of marginal cheapness" or PMC. Similarly, the intersection of the "too expensive" and "cheap" lines can be viewed as the upper bound of an acceptable price range. An alternative description is the "point of marginal expensiveness" or PME. Intersections where there is generally more agreement is the point at which the "expensive" line crosses the "cheap" line.
