Data

Definition

Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.

Qualitative vs Quantitative

Data can be qualitative or quantitative

1. Qualitative data is descriptive information (it describes something)
2. Quantitative data is numerical information (numbers)

 

 Quantitative data can also be Discrete or Continuous.

1. Discrete data can only take certain values (like whole numbers)
2. Continuous data can take any value (within a range) 

 

More Examples:

Qualitative:

• Your friends' favorite holiday destination
• The most common given names in your town
• How people describe the smell of a new perfume

Quantitative:

• Height (Continuous)
• Weight (Continuous)
• Petals on a flower (Discrete)
• Customers in a shop (Discrete)
