Peer reviewed Peer reviewed
Direct linkDirect link
Mudford, Oliver C.; Martin, Neil T.; Hui, Jasmine K. Y.; Taylor, Sarah Ann – Journal of Applied Behavior Analysis, 2009
The three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

Behavior States: Now You See Them, Now You Don't.
Mudford, Oliver C.; Hogg, James; Roberts, Jessie – American Journal on Mental Retardation, 1999
A study attempted to replicate a previous study that presented reliability data from recordings of behavior state using a 13-category coding system. Replication was unsuccessful. Obtained mean percentage agreement on occurrence for individual behavior state and participants (n=34) ranged across observer pairs from 0 to 58 percent. (Contains 13…

The Representativeness of Observational Samples of Different Durations.
Peer reviewed Peer reviewed
Mudford, Oliver C.; And Others – Journal of Applied Behavior Analysis, 1990
The representativeness of behavioral observation samples with durations of less than the whole time of interest was investigated with five profoundly mentally retarded physically handicapped adults in an institutional setting. It was found that the session representativeness was a function of the relative duration of the behavioral categories and…
