4. What is a dependent variable? Provide at least two examples
A dependent variable is a variable that is affected or influenced by changes in another variable, which is referred to as the independent variable. In an experiment, the dependent variable is the outcome or response that the researcher measures or observes.
Examples of dependent variables:
1. In a study investigating the effect of a new drug on reducing blood pressure, the dependent variable would be the blood pressure levels of the participants. The researcher would measure the changes in blood pressure as a result of administering the drug.
2. In a study examining the impact of different teaching methods on student performance, the dependent variable would be the students' test scores. The researcher would measure the changes in the test scores and compare them based on the teaching method used.
