• Mathematics and physics

• Psychology and sociology

• Experiments and surveys

Which data collection method involves in-depth analysis of a single individual or event?

• Surveys

• Sampling

• Case studies

•  Experiments

Which of the following is an example of nominal data?

• Temperature in Celsius

• Height in centimeters

• Types of animals

• Likert scale responses

Which type of data involves categories without any inherent order?

• Interval data

• Nominal data

• Ratio data

• Ordinal data

In ordinal data, the order of categories matters, but:

• Categories are numeric

• Ratios between categories are meaningful

• Differences between categories are uniform

• Differences between categories might not be uniform or meaningful

What differentiates ratio data from interval data?

• Ratio data involve categories.

• Ratio data have a true zero point.

• Interval data have uniform differences between values.

• Interval data involve a specific order of categories.

Which of the following is an example of ratio data?

• Education levels (e.g., high school, bachelor's)

• Colors of cars

• Likert scale responses

• Income in dollars
