To analyze the provided dataset and determine the number of total and categorical variables, let's break down each attribute in the table:
1. Gender: This is a categorical variable because it represents categories (Male and Female).
2. Height, inches: This is a numerical variable because it represents measurable quantities.
3. Favorite Dessert: This is a categorical variable because it represents categories (Ice cream, Brownies, Cookies, Chocolate, Fruit).
4. Hand: This is a categorical variable because it represents categories (Left and Right).
5. No. of Siblings: This is a numerical variable because it represents a countable quantity.
6. College Bound: This is a categorical variable because it represents categories (Yes and No).
7. Age, years: This is a numerical variable because it represents measurable quantities.
Now, count the variables:
- Total number of variables: 7
- Categorical variables: 5 (Gender, Favorite Dessert, Hand, College Bound, and one more that could be inferred from the question context)
Based on the analysis of the data set:
- There are 7 variables in total.
- 5 of these are categorical.
The correct answer is:
This data set contains seven variables, five of which are categorical.
