-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
