Question

What are strengths of Single Subject Quantitative Research? Provide an example.

What is the meaning of baseline in Single Subject Research and how is it used to determine changes

Answer 1

I think, single-subject research designs have significant methodological advantages
over large-sample research designs that could be used to facilitate more rapid clinical research advances.
First, such designs can demonstrate clear causal relations between intervention and behavior change
with much more efficiency than large-sample designs.
Second, single-case research designs offer much more flexibility in the implementation and evaluation
of interventions than large-sample designs.
Third, the assessment methods used in single-subject research designs provide for the evaluation of
individual change patterns in the data. Large sample designs most often employ only pre- and post-
treatment assessment, precluding evaluations of how and why individuals change over the course of
treatment .
A baseline is established for several participants and the treatment is then introduced to each participant at a different time. The plotting of individual participants' data, examining the data, and making judgements about whether and to what extent the independent variable had an effect on the dependent variable.
