Types of Data: Nominal and Ordinal

The video tutorial introduces the types of data in statistics, focusing on numerical and categorical data. Numerical data is divided into discrete and continuous types, with examples illustrating each. Categorical data is further divided into nominal and ordinal types, with examples provided. The tutorial concludes with an analysis of a data table, identifying the type of data in each column.

What are the two main types of data discussed in the video?

• Textual and Categorical

• Discrete and Continuous

• Numerical and Categorical

• Numerical and Textual

Which of the following is an example of discrete data?

• The length of a shirt

• The cost of a shirt

• The number of shirts

• The weight of a shirt

Continuous data is typically represented by which type of number?

• Whole numbers

• Negative numbers

• Imaginary numbers

• Decimal numbers

What does nominal data represent?

• Data that is continuous

• Data with a specific order

• Data that can be named

• Data that is numerical

Which of the following is an example of ordinal data?

• Customer names

• Shirt sizes: small, medium, large

• The price of a shirt

• The number of shirts

In the context of the video, what does the term 'ordinal' imply?

• Data that is numerical

• Data with a specific order

• Data that is continuous

• Data that can be named

Which data type is used to categorize items like 'shirt' or 'pant'?

• Nominal data

• Ordinal data

• Continuous data

• Discrete data

What is the significance of order in ordinal data?

• Order is only sometimes important

• Order is important

• Order is irrelevant

• Order is not important

In the table example, which column represents nominal data?

• Size

• Cost

• Quantity

• Customer name

What type of data is represented by the 'cost' column in the table example?

• Continuous data

• Discrete data

• Ordinal data

• Nominal data
