This document discusses experimental research and its practical applications. It provides examples of how to identify independent and dependent variables in equations and hypotheses. The examples show that independent variables are those values that determine the dependent variables. Dependent variables are values that are determined by the independent variables. Exercises are given to identify independent and dependent variables in different scenarios involving drinking mountain dew before bed and dissolving sugar in water as the temperature changes.
Experimental research and its application
- 2. • REPORTER: • MARIA KATRINA S. MACAPAZ
- 20. Graphing Independent and Dependent Variables
- 21. • Example 1: If we take an equation y = f(x) = In x, i.e. y depends on x. if we take different different values of x then we find some different values of y. x = 1 then y = In 1 = 0, x = 2 then y = 0.693 x = 3 then y = 1.09, x = 5 then y = 1.60x = 7 then y = 1.945
- 23. Important: • In Mathematics, independent variables are those values that determine the value of other variables. Dependent variables are those, whose values are determined with the help of the independent variable.
- 24. EXERCISES: • If I drink mountain dew before bed,then I will not sleep very much. • (Independent or Dependent) 1. DrinK mountain dew.____________ 2. amount of sleep. _______________
- 25. Answer: • 1. independent • 2. dependent
- 26. Hypothesis example: • If water temperature increases, then the amount of sugar dissolved in the water will also increase. • Independent or dependent? • 1. amount of sugar that dissolves, measured in grams. _______________________ • 2.water temperature_________________
- 27. Answer: • 1.dependent variable • 2. Independent variable
