Chapter 1: Problem 13

A blanket idea covering several related principles is called a (a) theory (c) concept (b) hypothesis (d) conclusion

Short Answer

Expert verified
(a) theory

Step by step solution

01

Understanding the question

We are asked to determine which term best describes a blanket idea that encompasses several related principles. Each option given should be considered to see which has this definition.
02

Analyzing the options

Let's examine each choice: (a) Theory typically refers to a well-substantiated explanation of some aspect of the natural world that is repeatedly confirmed through observation and experimentation. (b) Hypothesis is a proposed explanation made on the basis of limited evidence. (c) Concept usually refers to a general idea or understanding that organizes thoughts or notions. (d) Conclusion is a final decision or judgment. Among these, a theory generally covers multiple principles.
03

Selecting the correct answer

Based on the definitions, a theory is most aligned with the idea of covering several related principles as it involves a systematic explanation that ties together various related ideas and principles.
04

Confirming the answer

We have established that the term 'theory' is often used to describe a comprehensive framework that integrates various principles. Thus, the correct answer is most likely 'a theory'.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Hypothesis
A hypothesis is the starting block of scientific inquiry. It's a proposed explanation or assumption made based on limited evidence as a starting point for further investigation. Scientists formulate hypotheses to explain observations or phenomena they encounter in the world.
  • Hypotheses are not guesses; they are informed assumptions that guide the research process.
  • They are typically testable and measurable, meaning you can design experiments to support or refute them.
  • They set the stage for experimentation and further observation.
In summary, a hypothesis provides a preliminary framework that guides the direction of scientific research. From here, scientists conduct tests, gather data, and determine whether the hypothesis holds true or needs revision.
Concept
A concept is a mental grouping of ideas or an understanding that serves as an organizing principle for thoughts and notions. Concepts help us to categorize and group different observations and pieces of information.
  • Concepts act as building blocks for theories by providing a common understanding or framework for easy reference.
  • They simplify complex information by creating general categories.
  • Examples of concepts could include gravity, ecosystems, or democracy.
Overall, a concept helps to simplify and clarify by providing a universal language that aids discussion and understanding within a particular field of study. It often serves as a groundwork for more complex theories and ideas.
Conclusion
A conclusion is the final step in the scientific method and in logical reasoning. It represents a reasoned judgment based on evidence gathered during experimentation and observation.
  • Conclusions summarize findings and state whether the initial hypothesis was supported or not.
  • They are drawn after the careful analysis of data collected during research.
  • Conclusions provide clear answers to the research questions posed at the beginning of the experimental process.
In essence, a conclusion helps in closing a scientific inquiry by encapsulating the findings and allowing for the refinement of theories or the formulation of new hypotheses as required.
