Is the following variable discrete or continuous? Number of cars in the parking lot. Determine the level of measurement of the following variable: Monthly temperatures: 60 F, 64 F,... Is the following variable discrete or continuous? Number of cars in the parking lot. Determine the level of measurement of the following variable: Monthly temperatures: 60 F, 64 F, 68 F, 75 F, 80 F. Determine the level of measurement of the following variable: Survey responses of 'Good, Better, Best'.
Understand the Problem
The question is asking about the nature of a variable, specifically whether it is discrete or continuous, and how to determine the level of measurement for certain data types such as monthly temperatures and survey responses.
Answer
Discrete; Interval; Ordinal
The number of cars in the parking lot is a discrete variable. Monthly temperatures are at the interval level of measurement. Survey responses of 'Good, Better, Best' are at the ordinal level of measurement.
Answer for screen readers
The number of cars in the parking lot is a discrete variable. Monthly temperatures are at the interval level of measurement. Survey responses of 'Good, Better, Best' are at the ordinal level of measurement.
More Information
The number of cars is counted in whole numbers, making it discrete. Temperatures are measured on a consistent scale, making them interval data. 'Good, Better, Best' has an inherent order without a precise difference between levels, thus ordinal.
Tips
A common mistake is confusing interval and ratio levels; interval lacks a true zero point.
