what is the following answers for the definitions i don't understand;

control, repetition, validity, reliability, accuracy, controlled variable, independent and dependent variable, hypothesis?

We'll be happy to help you understand these definitions if you post the dictionary meanings that pertain to your subject.

Sure! Here are the definitions for the terms you mentioned:

1. Control: In the context of scientific experiments and studies, control refers to a standard or reference condition against which other conditions are compared. It helps researchers isolate and identify the effects of specific variables being tested.

2. Repetition: Repetition, also known as replication, refers to the act of conducting an experiment or observation multiple times in order to validate the results and ensure their consistency. Repetition helps increase the reliability of the findings.

3. Validity: Validity refers to the extent to which an experiment, test, or study measures what it intends to measure. In other words, it assesses the accuracy and meaningfulness of the data or conclusions obtained.

4. Reliability: Reliability relates to the consistency and stability of data or measurements. It indicates the degree to which a particular assessment, experiment, or instrument consistently produces the same results upon repetition.

5. Accuracy: Accuracy refers to the degree of closeness between a measured value or result and the true or accepted value. It suggests how correct or precise a measurement or observation is.

6. Controlled variable: Also known as a constant, a controlled variable is a factor or element that is intentionally kept unchanged throughout an experiment or study. By keeping certain variables constant, researchers can focus on the effects of the variables they specifically want to examine.

7. Independent variable: An independent variable is the variable in an experiment that is manipulated or controlled by the researcher. It is the factor being intentionally changed or tested to observe its impact on the dependent variable.

8. Dependent variable: The dependent variable is the variable that is observed or measured in an experiment. It is influenced by the independent variable and changes in response to the manipulation of the independent variable.

9. Hypothesis: A hypothesis is an educated guess or prediction made by a researcher prior to conducting an experiment. It is a proposed explanation for a phenomenon or a relationship between variables that can be tested and analyzed.

Remember, these definitions are not exhaustive, and depending on the context, the meanings might vary slightly. However, these explanations should provide you with a good starting point to understand these terms.
