Types of Data

generally, there are two types of data

1. Categorical Data

   • Nominal data
   • Ordinal data

2. Numerical Data

   • Discrete data
   • Continuous data

Categorical Data

• Categorical data represents groups or categories.
• qualitative data classified into categories.
• there are two type of data lie under categorical data

Ordinal Data

• So, when we talk about Nominal data its directly mean data with an Order associated with it.

Copy
Low < Medium < High

Nominal Data

• Nominal data means no order associated with the data.

Copy

2. BMW, Audi, Ferrari etc

Numerical Data

• Data Expressed with digits and can be measurable.

Copy
1. Height
2. Price
3. blood pressure
etc ...

Descrete Data

• Descrete data represents items that can be counted.
• Data that is descrete from one another having a quite of range between them.

Copy
1. 0,1,2,3
2. 100,200,300,301

Continuous Data

• Continuous Data represents measurements; their possible number can not be counted and ccan only be described using intervals on real number line.

Copy
1. 8.0, 8.1, 8.33, 8.3456, 8.8979, 9.0231
