Introduction:
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. It provides tools and techniques for making decisions and drawing conclusions based on data. The term "statistics" is a plural noun, indicating that it encompasses various aspects of the field.

Explanation:
The correct answer to the question is option 'C' - Statistical data. Here's an explanation of why:

Statistical methods:
- Statistical methods refer to the techniques and procedures used to collect, analyze, and interpret data.
- While statistics as a field encompasses statistical methods, it is not specifically indicated by the plural form of the noun.

Descriptive statistics:
- Descriptive statistics involves summarizing and describing data using numerical measures such as measures of central tendency (mean, median, mode) and measures of variability (range, standard deviation).
- While descriptive statistics is a part of statistics, it does not fully encompass the plural form of the noun.

Statistical data:
- Statistical data refers to the collection of numerical information or facts that have been analyzed and interpreted using statistical methods.
- The plural form of "statistics" indicates that it includes the data itself, which is an essential component of the field.

Inductive statistics:
- Inductive statistics, also known as inferential statistics, involves making predictions, inferences, or generalizations about a population based on a sample.
- While inductive statistics is a part of statistics, it does not fully encompass the plural form of the noun.

Conclusion:
In summary, statistics as a plural noun indicates statistical data. While it encompasses various aspects of the field such as statistical methods, descriptive statistics, and inductive statistics, the primary focus is on the collection, analysis, and interpretation of data. Statistical data is the foundation on which statistical methods and techniques are built, making it the correct answer to the question.
