Types of Data and Classification

The video tutorial explains the two main types of data: categorical and numerical. Categorical data is divided into nominal and ordinal, where nominal data is simply named categories, and ordinal data has an implied order. Numerical data is divided into discrete and continuous, where discrete data involves specific values, often whole numbers, and continuous data can take any value within a range. The tutorial also discusses tricky cases like shoe sizes, which can be both discrete and continuous depending on the context.

• The number of cars

What type of data involves numbers?

• Qualitative

• Quantitative

• Nominal

• Ordinal

What is nominal data?

• Data with a specific order

• Data that is named

• Data that involves numbers

• Data that is continuous

Which of the following is an example of nominal data?

• Small, Medium, Large

• Red, Green, Blue

• 1, 2, 3

• High, Medium, Low

What characterizes ordinal data?

• It has an implied order

• It is named

• It involves numbers

• It is continuous

Which of the following is an example of ordinal data?

• Ford, Holden, Toyota

• Red, Green, Blue

• 1, 2, 3

• Best, Preferred, Acceptable

What is discrete data?

• Data that is continuous

• Data with specific, separate values

• Data that involves categories

• Data that can take any value

Which of the following is an example of discrete data?

• The number of children

• The length of a river

• The mass of a car

• The height of a tree

What is continuous data?

• Data that can take any value within a range

• Data that involves categories

• Data that is named

• Data with specific, separate values
