Show hintHide hint
What do we do to improve the reliability of our results?
3Question 3.
Random errors are predictable and can be easily corrected.
- True

Show hintHide hint
Think about whether all errors follow a pattern.
4Question 4.
What is the best way to minimize the effects of random errors?
- Take one measurement.

- Ignore them.
Show hintHide hint
Consider how averages work when we have multiple values.
Question 5.
You are conducting a temperature measurement on a given day using two different thermometers multiple times. How would you analyze the data to account for random errors?
Show hintHide hint
What statistics would give you a sense of typical measurement versus variability?
Question 6.
Design a study where random errors are intentionally introduced in measurements. Discuss how you would quantify their significance.
Show hintHide hint
Consider what method ensures you can determine the extent of those random influences.
