Q.1
When the hypothesis is supported, the data is in...
  • dispute
  • agreement
  • negative
  • borderline
Q.2
If the data does not support the hypothesis, you should ...
  • repeat the experiment several times to ensure the accuracy and reliability of the results
  • write a conclusion based on this first experiment
  • give up
  • make up the results
Q.3
What is a hypothesis?
  • A prediction based on previous knowledge
  • A random guess
  • The results obtained
  • A statistical test
Q.4
Which of the following is an example of a hypothesis?
  • I think that the reaction will be slowed down
  • I think that the reaction will be faster
  • I think that if I increase the concentration of acid, the reaction will be faster
  • If I increase the concentration of acid, there will be more acid particles so I think the reaction will be faster because there will be more collisions
Q.5

Q.7
Why is a control used in scientific experiments?

  • To compare with the experimental group
  • To increase the sample size
  • To make it more likely that we get a good result
Q.8
Which of the following could be a practical reason for unexpected data which does not support the hypothesis?
  • Running out of time
  • Incorrect measuring of volumes
  • Being distracted
  • Working on your own
Q.9
How would you process the data to work out if your hypothesis is supported?
  • Work out the average and compare the groups of data
  • Draw a pie chart
  • Do more tests
  • Put the results into a table
Q.10
