Abstract

Control charts facilitating the use of sequential strategies of the updown or staircase type are described. The charts are easy to use and the relevant estimates may be derived very simply from the chart. An example is given in which both the 29.3% and 70.7% points on a response curve are estimated using the Up-Down-Transformed-Response (UDTR) procedure. The charts can be used in psychophysics and are also generally applicable to experiments or control processes involving binary responses.
