Study Notes

Variables in Scientific Research

A variable is a factor or characteristic that can be manipulated, measured, or observed in a scientific experiment.

Data in Scientific Research

The primary function of data in scientific research is to provide a basis for drawing conclusions, making inferences, and supporting hypotheses.

Participants in Scientific Research

In the context of scientific research, a participant refers to an individual or case that provides data for a study, often through direct observation, surveys, or experiments.

Parameters in Scientific Research

Parameters are numerical values that describe a population, such as mean, proportion, or standard deviation, which are used to make inferences about the population based on sample data.
The role of parameters in scientific research is to provide a point of reference for making inferences and generalizations about a larger population based on a sample of data.
