Paper 2

Question 0

Q2- Anomalies

Answer 0

Yes- one is far away from the line of best fit- example from results, and LOBF
No- all points close to LOBF- point furthest away from LOBF, LOBF suggestion, very close actually

Question 1

Q1

Answer 1

Hypothesis
Do your results support it
Show any pattern- the larger, the smaller etc
Example from results

Question 2

Q2/3- Reproducibility

Answer 2

Compare their results with your results
If some pattern, then investigation= reproducible
Only valid if same variables and investigated

Question 3

Q3- Mean

Answer 3

Repeated readings
Calculate mean
Add numbers up and divide by number of repeats
Not include anomalies

Question 4

Q4- Errors

Answer 4

Largest error/ cause of uncertainty
What could you do to reduce that were you to do the experiment again?
How would this reduce the error/ make you results reliable

Question 5

Q4- Range

Answer 5

What the independent variable was
Range used was
This was good because it was wide enough to show a clear pattern between variables

Question 6

Case Study Questions

Answer 6

Compare the results
Usually one will investigate different variables, so not valid
Look for similar patterns
Sketch graph- label axis and use units
Context- why would the information be useful to the manufacturers?
