Classifying Statistical Data
Bayani Gaba-gaba
Before you can analyse data, you have to understand what kind of data you have. Is it numbers or categories? Can it take any value, or only whole steps? The answers decide which charts, averages and methods make sense. Classifying data is the quiet first step that keeps every later calculation honest.
In this lesson you will sort data into qualitative and quantitative, and quantitative data into discrete and continuous. You will then organise raw data into tally and frequency tables, and group large data sets into class intervals. These skills turn a messy list of observations into a tidy table ready for analysis.
