Exploring Independent and Dependent Variables

The video tutorial from Mumu Math and Science explains the difference between independent and dependent variables. It provides examples such as car color affecting temperature, tree height depending on water, and bananas influencing blood pressure. The video also introduces the DRY MIX method for graphing variables, where 'D' stands for dependent, 'R' for responding, 'Y' for y-axis, 'M' for manipulated, 'I' for independent, and 'X' for x-axis. The tutorial concludes with a reminder to subscribe for daily educational content.

What is the term used for a variable that stands alone and is not changed by other variables?

• Independent variable

• Constant variable

• Dependent variable

• Control variable

Which variable is known as the 'responding variable'?

• Dependent variable
