Independent vs. Dependent Variables Explained

This video tutorial explains the concepts of dependent and independent variables, providing definitions and examples. It introduces the DRY MIX acronym to help remember the roles of these variables. The video includes an example problem to identify variables in a scenario and offers a practice problem for viewers to solve. The tutorial concludes with suggested practice problems to reinforce learning.

What does an independent variable do?

• Remains constant throughout the experiment

• Causes changes in other variables

• Is affected by external factors

• Changes in response to other variables

What role does the dependent variable play in an experiment?

• It is used to predict experimental outcomes

• It remains unchanged throughout the experiment

• It responds to changes in the independent variable

• It is controlled by the experimenter

Which of the following best describes a dependent variable?

• It influences other variables in the experiment

• It remains constant to provide reliable data

• It changes in response to another variable

• It is not necessary for experimental conclusions

Which variable is commonly represented by 'x' in experiments?

• Manipulated variable

• Independent variable

• Control variable

• Dependent variable

In the DRY MIX acronym, what does 'M' stand for?

• Minimized

• Moderated

• Measured

• Manipulated

What does the 'D' in DRY stand for in the context of variables?

• Direct

• Determined

• Dependent

• Dynamic

What is the primary purpose of the DRY MIX acronym?

• To design experimental setups

• To calculate experimental errors

• To help remember variable roles

• To simplify complex formulas

• Dependent

• Independent

• Control

• Constant

In the scenario with Mr. H and pizzas, what determines the cost?

• The ingredients of the pizza

• The size of the pizza

• The number of pizzas

• The type of pizza

Which variable would a baker control in the given scenario?

• Amount of batter used

• Type of batter

• Cooking time

• Number of pancakes
