ABSTRACT
The field of Human-Robot Interaction gained prominence with the advent of the so called “Human-Robot Interaction” conference in 2006, which to date represents the flagship conference in the field. Quantitative data is usually collected through questionnaires, surveys, by observing participants' behaviour in lab experiments or by observing them in the field, such as in their schools or within their families. A good literature review will summarize what work has already been done in the area of interest and what gaps in the knowledge may exist. Educational robots research in particular should also look into literature in the field of educational technology to ascertain the gaps in techniques that do not involve robots but may utilize other smart artefacts. Conducting empirical research implies collecting various types of data from research participants. The main goal of any statistical analysis is to exclude the possibility that the differences in the measurements observed are due to chance alone.
