Question

match the following terms: prediction outlier data trial research evidence conclusion constant hypothesis

• ______: a tentative, testable, and falsifiable explanation for a phenomenon or observation, often based on existing knowledge and acting as a starting point for further investigation. it is a proposed answer to a research question.
• ______: a factor that is deliberately kept unchanged throughout an experiment to ensure that only the independent variable affects the dependent variable. it ensures the experiment is fair and reproducible.
• ______: a synthesis of key findings derived from the analysis of data, which explains the significance of the results and addresses the research problem, often providing a \take - home\ message.
• ______: data, facts, and observations collected during research that support or refute a hypothesis.
• ______: a systematic process of investigation, which includes developing questions, formulating hypotheses, collecting data, and analyzing results to increase knowledge.
• ______: a single, controlled execution of an experiment or test, often one of many in a study designed to verify results.
• ______: the information, measurements, or observations gathered during an experiment or study that are subsequently analyzed to test a hypothesis.
• ______: a data point that differs significantly from the general trend or other observations in a data set, potentially indicating measurement error or novel, unexpected behavior.
• ______: a specific, expected outcome stated in advance, often written in \if - then\ format, describing what should happen if a hypothesis is correct.

Explanation:

1. For the first blank: The description matches the definition of a hypothesis, which is a tentative explanation for a phenomenon.
2. For the second blank: A factor kept unchanged in an experiment is a constant.
3. For the fifth blank: The systematic process of investigation is research.
4. For the sixth blank: A single execution of an experiment is a trial.
5. For the seventh blank: Information gathered during a study is data.
6. For the eighth blank: A data point differing from others is an outlier.
7. For the ninth blank: A specific expected outcome is a prediction.

Answer:

• Hypothesis: A tentative, testable, and falsifiable explanation for a phenomenon or observation, often based on existing knowledge and acting as a starting point for further investigation. It is a proposed answer to a research question.
• Constant: A factor that is deliberately kept unchanged throughout an experiment to ensure that only the independent variable affects the dependent variable. It ensures the experiment is fair and reproducible.
• Research: A systematic process of investigation, which includes developing questions, formulating hypotheses, collecting data, and analyzing results to increase knowledge.
• Trial: A single, controlled execution of an experiment or test, often one of many in a study designed to verify results.
• Data: The information, measurements, or observations gathered during an experiment or study that are subsequently analyzed to test a hypothesis.
• Outlier: A data point that differs significantly from the general trend or other observations in a data set, potentially indicating measurement error or novel, unexpected behavior.
• Prediction: A specific, expected outcome stated in advance, often written in "if - then" format, describing what should happen if a hypothesis is correct.
