Types of Data and Their Characteristics

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 types of data in each column.

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

• Numerical and Categorical

• Numerical and Textual

• Discrete and Continuous

• Textual and Categorical

Which type of numerical data is represented by whole numbers?

• Continuous

• Nominal

• Ordinal

• Discrete

What is an example of continuous data?

• Sizes of shirts

• Types of clothing

• Cost of a shirt

• Number of shirts

What does 'nominal' data refer to?

• Data with a specific order

• Data that is always numerical

• Data with decimal values

• Data that can be named

Which data type is described as having no discrete value and being continuous?

• Discrete

• Nominal

• Ordinal

• Continuous

Which of the following is an example of ordinal data?

• Customer names

• Shirt sizes: small, medium, large

• Cost of items

• Number of items purchased

What is the key characteristic of ordinal data?

• It is always numerical

• It has a specific order

• It can be named

• It is always continuous

What is the significance of the order in ordinal data?

• It is not important

• It determines the data type

• It is crucial for categorization

• It affects the numerical value

In the table example, what type of data is 'customer name'?

• Ordinal

• Nominal

• Continuous

• Discrete

What type of data is 'quantity' in the table example?

• Continuous

• Ordinal

• Discrete

• Nominal
