Solution Steps

To determine whether a column represents qualitative or quantitative variables, we need to understand the nature of the data in each column. Qualitative variables describe categories or qualities, while quantitative variables represent numerical values that can be measured.

  1. Rank: This is a numerical value indicating order, so it is a quantitative variable.
  2. Book: This is a name or title, which is a category, so it is a qualitative variable.
  3. Author(s): This is a name, which is a category, so it is a qualitative variable.
  4. Language: This is a category describing the language, so it is a qualitative variable.
  5. Year Published: This is a numerical value indicating a year, so it is a quantitative variable.
  6. Sales: This is a numerical value indicating the number of copies sold, so it is a quantitative variable.
  7. Genre: This is a category describing the type of book, so it is a qualitative variable.
Step 1: Identify Variable Types

We analyze each column in the dataset to determine whether it represents qualitative or quantitative variables.

  • Rank: This column contains numerical values indicating the order of the books, thus it is classified as a quantitative variable.
  • Book: This column contains titles of books, which are categorical in nature, making it a qualitative variable.
  • Author(s): This column lists the names of authors, which are also categorical, hence it is a qualitative variable.
  • Language: This column indicates the language of the books, which is a category, so it is a qualitative variable.
  • Year Published: This column contains numerical values representing the year of publication, classifying it as a quantitative variable.
  • Sales: This column indicates the number of copies sold, which is a numerical value, thus it is a quantitative variable.
  • Genre: This column describes the type of book, making it a qualitative variable.
Step 2: Summarize Findings

Based on the analysis, we summarize the variable types for each column as follows:

  • \( \text{Rank} \): quantitative
  • \( \text{Book} \): qualitative
  • \( \text{Author(s)} \): qualitative
  • \( \text{Language} \): qualitative
  • \( \text{Year Published} \): quantitative
  • \( \text{Sales} \): quantitative
  • \( \text{Genre} \): qualitative

Final Answer

The classifications for each column are:

  • The column Rank represents \( \text{quantitative} \) variables.
  • The column Book represents \( \text{qualitative} \) variables.
  • The column Author(s) represents \( \text{qualitative} \) variables.
  • The column Language represents \( \text{qualitative} \) variables.
  • The column Year Published represents \( \text{quantitative} \) variables.
  • The column Sales represents \( \text{quantitative} \) variables.
  • The column Genre represents \( \text{qualitative} \) variables.

Thus, the final answer is: \[ \boxed{ \begin{align_} \text{Rank} & : \text{quantitative} \\ \text{Book} & : \text{qualitative} \\ \text{Author(s)} & : \text{qualitative} \\ \text{Language} & : \text{qualitative} \\ \text{Year Published} & : \text{quantitative} \\ \text{Sales} & : \text{quantitative} \\ \text{Genre} & : \text{qualitative} \end{align_} } \]
