Determine the level of measurement of the following variable: Eye color. Is the following variable discrete or continuous? The daily volume of water through a leaky faucet. What type of sampling is used to determine customer opinion of their pricing?
Understand the Problem
The question is asking about statistical concepts such as levels of measurement for variables (eye color), the nature of a variable (discrete or continuous), and types of sampling methods used in surveys. This is related to understanding basic statistics and research methodology.
Answer
Nominal; Continuous; Cluster sampling.
- Eye color is measured on the nominal scale. 2. The daily volume of water through a leaky faucet is continuous. 3. The sampling method used is cluster sampling.
Answer for screen readers
- Eye color is measured on the nominal scale. 2. The daily volume of water through a leaky faucet is continuous. 3. The sampling method used is cluster sampling.
More Information
Eye color, being categorial, belongs to the nominal level of measurement, as it describes a characteristic without implying order. Water volume is continuous as it can take on infinite values. Cluster sampling involves dividing a population into clusters and surveying all members within selected clusters.
Tips
A common mistake is confusing nominal with ordinal: nominal data do not have a specific order. Continuous variables can take fractional values, unlike discrete variables.
