Hypothesis, Inference, etc.?

Question

What is the difference between a hypothesis, an inference, and a prediction? They are all made after taking observations but what is the main thing setting them apart? Also, what's the difference between a Control Group and a Constant?

Answer 1

a hypothesis is an educated guess that you think will happen before you do an experiment and a inference is something that you can infer....like the block is blue

Answer 2

okay...
a hypothesis is a statement made upon the outcome of data. An inference is basically an educated guess EX: The grass is wet so it must have rained. A prediction is an educated guess about the future outcome of experiment data. A control group is something you leave the same in an experiment so you can compare other items in the experiment to it EX: you are growing beans and want to see if their growing height has anything to do with what you water them with so you feed one salt water, one sugar water, and one plain water. The plain water would be your control. A constant is something you need to keep the same for data to be accurate EX: all of the bean plants would need the same amount of sunlight
