Answer:
Independent variable: Type of fertilizer
Dependent variable: Growth rate of carrots
Control variable: No fertilizer
Explanation:
An independent variable in statistics is defined as the variable that is manipulated, and a dependent variable is defined as the variable that is measured. A control variable is defined as a variable that doesn't change and is used to compare the other variables to. Furthermore, the independent and control variables are graphed on the <em>x</em>-axis, and the dependent variables are graphed on the <em>y</em>-axis.
In this case, the farmers <em>manipulate </em>the <em>type of fertilizer</em> they use to <em>measure </em>the <em>effect it has on growth</em>. The control variable would then be the carrots that grow without any fertilizer, because if the fertilizer does have an effect on growth, you would want to know how much or what kind of effect it has.
There once was a kid named John. He was a young and adventurous kid. One day he went into the forest. He was sort of peculiar about it. His friends told him stories that there was a witch who made kids like him disappear. He wanted to prove them wrong that there wasn’t a witch. He soon came across an old, creaky house. He went inside, trying not to make a sound. He tried to see what was inside with his flash light. As soon as he turned around, he saw something dash across the hallway. He was curious. It looked like a dog to him. He went into the room that the thing went it. The witch was standing there, waiting for him. He grabbed John and tied him to the chair. She was stirring a potion. John was trying to yell for help, but he couldn’t. He was too deep into the forest. The witch forced him to drink the potion. Then … POOF! He disappeared, and John was never to be seen again.
