Understanding Data Types

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

• Categorical and Numerical

• Qualitative and Quantitative

• Discrete and Continuous

• Primary and Secondary

Which of the following is an example of categorical data?

• Weight in kilograms

• Eye color

• Height in centimeters

• Number of siblings

What distinguishes numerical data from categorical data?

• Numerical data is always discrete

• Numerical data is always whole numbers

• Numerical data can be measured and expressed in numbers

• Numerical data is always continuous

Which of the following is a characteristic of discrete data?

• It can take any value within a range

• It is always represented in words

• It consists of distinct and separate values

• It is always measured in decimals

Which example best represents discrete data?

• The time taken to run a marathon

• The height of a building

• The number of books on a shelf

• The temperature in a room

What is a key feature of continuous data?

• It can only be whole numbers

• It can be measured to any level of precision

• It is always a fixed set of values

• It is always represented in categories

Which of the following is an example of continuous data?

• The speed of a car

• The number of students in a class

• The color of a car

• The type of fruit

Why is it important to know the type of data you are working with?

• It dictates how you might display the data

• It determines the type of analysis you can perform

• It helps in choosing the right data collection method

• It is not important at all

How can categorical data be visually represented?

• In a scatter plot

• In a pie chart

• In a line graph

• In a histogram

Which method is suitable for representing numerical data?

• Bar chart

• Pie chart

• Frequency histogram

• Venn diagram
