5. If calcium is given, then bone strength will increase.
Manipulated variable: ________________________________________________________________________
Responding variable: ________________________________________________________________________

Answers

1. Manipulated: Water

Responding: Growth Height

2. Manipulated: Chocolate Given

Responding: Amount of Homework

3. Manipulated: Trees with Leaves

Responding: Number of Bird Nests

4. Manipulated: Acid Rain

Responding: Fish Population

5. Manipulated: Calcium Given

Responding:  Bone Strength

Think about the manipulated variable as the changing item in the experiment. If this changes, the response will. (This is the Independent Variable)

Think of the Responding Variable as the result of the variable only can change when Manipulated is changed. (This is the Dependent Variable)

Hope This Helps :)

Manipulated variable in each case are watering of plants, number of chocolates, trees having leaves,water in acid rain, amount of calcium respectively and responding variables are growth  height, amount of homework,number of bird nests,fish population,bone strength.

What are variables?

Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.

There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable  which do not change
