[2] The term "big data" is about machines and "small data" is about people. [3] This is to say that eyewitness observations or five pieces of related data could be small data.
The item-total correlation approach is a way of identifying a group of questions whose responses can be combined into a single measure or scale. This is a simple approach that works by ensuring that, when considered across a whole population, responses to the questions in the group tend to vary together and, in particular, that responses to no individual question are poorly related to an ...
