To determine which of the options are categorical data, we need to understand what categorical data is. Categorical data are variables that can be divided into distinct groups or categories.
Now let's analyze each option:
A. Numbers of inches of rain: This is not categorical data because it is a numerical measurement, not divided into distinct categories.
B. Types of drinks: This is categorical data because drinks can be divided into distinct categories such as soda, juice, coffee, etc.
C. Lengths of movies (in minutes): This is not categorical data because it is a numerical measurement, not divided into distinct categories.
D. Weights of students: This is not categorical data because it is a numerical measurement, not divided into distinct categories.
So, the options that represent categorical data are:
B. types of drinks
Now, let's move on to the second question:
A statistical question is a question that anticipates an answer based on data that vary. It is not just about numbers, but about understanding the relationship between different variables and making inferences from data.
Therefore, the correct option that best describes a statistical question is:
D. a question that anticipates an answer based on data that vary
