The sky is blue
The sky is a nice colour
There are a lot of clouds in the sky
It isn't raining
Which is not a step in the scientific method?
Designing an Experiment
Analysing the Experimental results
Adding more variable to one of the experimental group to get the same effect
Which statement is correct?
An experiment can only prove the hypothesis is true
Testing is more reliable when using a larger sample size
Septic conditions are more reliable than sterile conditions
An effect in half the samples proves a hypothesis
Which of the following can be seen as being a clear hypothesis?
antibiotics don't cure viral diseases
some viral disease make you feel bad
Obesity is a leading cause of health problems

Define Placebo in terms of a medical trial?

A medicine which has no effect on a patient
Define Controlled experiment?
A controlled experiment is one in which all possible effects from variables are eliminated
An experiment done under any conditions
An experiment where external factors aren't an issue
A reliable tested out on a variety of people who have no characteristics in common
What is the null hypothesis?
A hypothesis that no possible solution exists
A hypothesis proving that a number will always have zero as a factor
A hypothesis in which something is being proved false in an effect or not experiment
A hypothesis in which there are no factors which had an effect
Define inductive reasoning?
Where an explanation is guessed based on personal feeling
A prediction is made because other people seem to think so
A generalization based on specific details
A specific idea based on generalized observations
Which isn't a correct characteristic of a good hypothesis?
It should be a general principle that holds across space and time
It should agree with available observations
It should be testable and potentially falsifiable. In other words, there should be a way to show the hypothesis is false; a way to disprove the hypothesis.
It doesn't have to be completely true or false, can be open to interpretation
Which is true of the scientific method?
The scientific method changes depending on the experiment being done
Inductive and deductive reasoning are both part of forming a hypothesis and predicting an outcome
It doesn't matter whether the hypothesis is biased as the experiment isn't dependant upon objectivity
