Identify the nominal variables.
A. Gender
B. Annoyance level
C. Caste
D. Temperature in Kelvin
E. Economic status
Choose the correct answer from the options given below:

Correct option is B

Nominal variables are categorical variables that do not have an intrinsic ordering or ranking. They are used to label or categorize data without any quantitative value. Examples of nominal variables include categories like gender, caste, or colors. In this question:
A. Gender and C. Caste are nominal variables as they are categories without any order or rank.
B. Annoyance level and E. Economic status can be considered ordinal variables because they imply a ranking or level (e.g., high annoyance, low annoyance).
D. Temperature in Kelvin is a continuous interval variable that represents a quantitative value on a fixed scale with equal intervals but no true zero.
Information Booster:
Nominal Variable: Used to label categories without any natural order. Examples include ethnicity, country, and language.
Ordinal Variable: Has an order or ranking but does not quantify the difference between levels (e.g., satisfaction ratings).
Interval Variable: A scale with meaningful intervals but no absolute zero, like temperature in Celsius or Fahrenheit.
Ratio Variable: Has an absolute zero and meaningful ratios, like weight or height.
Discrete Variable: Represents countable items, such as the number of students.
Continuous Variable: Represents measurements that can take any value within a range, like temperature or height.
