Numerical Data: data that has been assigned a numeric value. Numerical data can be:
Discrete - data that can be counted but that can only have a particular value, for example the number of pieces of fruit in a bowl
Continuous - data that is not restricted to any particular value, for example the temperature outside, which is measured on a continuous scale.
Categorical Data: data is split into two or more categories. Categorical data can be:
Nominal - data that can be arranged into categories but not ordered, for example arranging shoes by colour or athletes by gender
Ordinal - data that can be arranged into categories that have an order, for example levels of education from high school to postgraduate degrees.
