Scientific Method: Review Quiz 2017 End Of Unit Practice

The correct answer is "Procedure" because when testing, it is important to have a clear and well-defined procedure in place. This includes outlining the steps to follow, the variables to control, and the expected outcomes. A procedure helps ensure that the testing is conducted consistently and accurately, allowing for reliable results to be obtained. Without a proper procedure, the testing process may be disorganized and the results may be invalid or unreliable.

Observation refers to what one notices or senses while performing the activity. It involves carefully watching and taking note of any relevant information or changes that occur during the activity. Observation is an important part of the scientific method as it helps in gathering data and drawing conclusions based on the evidence observed.

The conclusion is the result or outcome that is derived from the data and analysis. It is the final statement that is made based on the evidence and observations gathered during the experiment or study. The conclusion helps to determine whether the hypothesis was supported or not. It summarizes the relationship between the hypothesis and the test results, providing a clear and concise summary of the findings.

The correct answer is "Experiment" because it is the process that is used to test an idea. The theory provides the basis for the idea, the process outlines the steps to be followed, and the control is used as a comparison. However, it is the experiment that actually puts the idea to the test and allows for the collection of data and evidence to support or refute the hypothesis.

In research, a problem refers to an area or issue that needs to be investigated or explored. It is the starting point of a research study, as it identifies the gap or problem that needs to be addressed. Without clearly defining the problem, it would be difficult to conduct any research. Qualitative and quantitative research are two different approaches or methods used to gather data and analyze information. Hypothesis, on the other hand, is a tentative statement or prediction that is tested through research. However, the given answer "Problem" is the most relevant and accurate term among the options provided.

In testing, measurements refer to the collection of information or observations that are recorded during the testing process. These measurements can include various types of data, such as numerical values, qualitative descriptions, or binary outcomes. By analyzing and interpreting this data, testers can gain insights into the performance, behavior, and quality of the system or product being tested. Therefore, the correct answer is "Data."

The correct answer is "Hypothesis" because in the scientific method, a hypothesis is a proposed explanation or solution to a problem or question. It is an educated guess that is based on prior knowledge and observations. The hypothesis is then tested through experimentation and data analysis to determine if it is supported or refuted. Therefore, the hypothesis is a crucial step in the scientific process as it guides the research and investigation.

The correct answer is "Independent variable." In research, an independent variable is a factor that is manipulated or changed by the researcher to observe its effect on the dependent variable. It is called "independent" because it is not influenced by other variables and is under the control of the researcher. In this context, the isolated factor being tested is the independent variable, as it is the variable that is being manipulated to test the suggested problem solution.

A law is a statement that describes a natural phenomenon or relationship that has been consistently observed and verified through experimentation and observation. It is a generalization that applies to a wide range of situations and is supported by empirical evidence. Laws are often used to make predictions and guide scientific understanding of the natural world. Unlike theories, laws do not provide explanations for why a phenomenon occurs, but rather describe what will happen under certain conditions.

A theory is an explanation of how nature works that is supported by a substantial amount of evidence. It is a well-established and widely accepted explanation that has been tested and verified through scientific methods. Theories are often used to explain complex phenomena and provide a framework for further research and understanding. Unlike a hypothesis, which is an educated guess or prediction, a theory is backed by extensive evidence and has withstood rigorous testing. Therefore, the correct answer is theory.

A dependent variable is a factor that may change in response to the test factor. In an experiment, the independent variable is manipulated or controlled by the researcher, while the dependent variable is the outcome or result that is measured or observed. It is called dependent because it depends on the independent variable and changes accordingly.
