| Abstract: Graphical displays of data help with analysis and interpretation of the targeted response and communication with others about progress. Selecting the graphical display that best suits the measurement system is a critical skill for behaviour analysts particularly when making clinical decisions. One such graphical display is a standard celeration chart (SCC), designed in the 1960’s in an attempt to make visual inspection easier. However, since the introduction of the SCC, it has not undergone experimental review of its utility. We examined the feasibility and reality of using SCC methodology for decision making regarding paediatric feeding data. Retrospectively, we compared equal interval graphs to ratio charts. The comparisons highlighted several barriers to use with the data. We suggest that current SCC research is not conclusive to ensure a consistent method of calculation and data plotting, regardless of the behaviour. This presentation highlights the immediate need for research into the validity of this chart and the lack of standardisation in the use of the chart to interpret behaviour change data. We point out that regarding a graphical display that is a ‘more stringent’ version of visual display, the SCC and a linear graph are equal. |
