Single sample resesearch design (SSRD) as a way to assess individual client needs within E-commerce applications
Abstrakt
Single Sample Research Designs (also referred to as Small N experimental designs) are designs that can be applied when the sample size is one or when a number of individuals are considered as one group. These designs are often used to study the behavioural change or to assess individual needs as a > result of some experimental intervention or treatment.
Authors present SSRD > in combination with time series design as an effective and efficient way to > improve understanding affective reactions during human computer interaction > within e-commerce applications. They describe 3 basic types of SSRD: A-B-A > Withdrawal Design, Multiple-Baseline Design and Alternating Treatment Design in a combination of neurophysiological measurement such as heart and breath rate, eye tracking, skin conductivity, and other direct and indirect observation methods.
At the end of the paper advantages and limits of presented method are mentioned as well as statistical obstacles.
