Learning Activity 4: Iv and DV Worksheet IVs and DVs are essential in experiments where cause and effect relationships are predicted between independent variables (IV) and dependent variables (DV). For instance, researchers might want to know whether blueberry consumption increases maze-running performance among mice.
Entry and exit tickets are brief prompts that enable students to consider an issue independently, discuss it in pairs, and ultimately share it with their whole class. They work best when questions promote problem-solving and critical analysis.
Independent variable
Changed variables you manipulate to test whether they affect dependent variables are often called predictor or predictor variables.
Katiana experimented to see which liquid would best support bean cultivation. She experimented with Coca-Cola, lemonade, and plain water as irrigation sources before measuring how tall her beans had grown after one week.
Researchers looking into how playing video games affects teenage memory and mood are conducting experiments involving groups of teenagers at different levels of gaming and observing any effects on memory and mood, using different IV levels and one class for DV. Their data may be quantitative or qualitative. Researchers must make clear and distinct roles between IV and DV during such studies.
