In this video I explain the strengths and limitations of the 3 measures of central tendency: the mean, the median, and the mode. This is part of a key theme of statistics, which is the importance of the choices researchers make in how to summarize and present their data.

www.psychexamreview.com In this video I consider how it is that we improve our skills and abilities and how children make progress through different stages of development. This brings us to the work of Soviet psychologist Lev Vygotsky and his notion of the zone of proximal development. This refers to tasks outside of a child's current level of ability that can be accomplished with assistance (or scaffolding) from a parent, teacher, or peer. Like these videos?
