Statistics Definition:

-A branch of mathematics, dealing with the collction, analysis, interpretation, presentation and organisation of data.

-Statiscian Sir Arthur Lyon Bowley defines statistics as ”Numerical statemtns of facts in any department of inquiry placed in relation to each other.”

-A collection of quantitative data.

There are different types of data:

  • Numerical Data- This data has meaning as a measurement, discrete data represent items that can be counted, continuous data represents measurement
  • Categorical Data- Represent characteristics
  • Ordinal Data mixes numerical and catagorical data
  • Discriptive statistics is used to describe and summarise data
  • Numerical measres such as average, standard deviation and correlation are used to describe the features of a set of data
  • Inferential statistics studies  a statistical scope

I found some statistics on the NISRA website and jotted down some quick notes.
