Notes for Sample Bias/Measuring Validity etc
- Generalization can occur by basing the result on sample taken from a study on a
significant number of people.
- Have to determine: the right size, measure validity and bias in sampling
- 'Generalization' is the process of moving from specific observations about some
individuals within a group to general claims about the members of the group.’
- Thought: how to identify when it is explicit or implicit?
- The process: SAMPLE (some of the population) GENERALIZATION (the whole
Occurs at intermediate conclusion to final conclusion
- Tricky qualification?
- Clarify the parameter thingy / population parameter value etc

- Tips on slide 125
- Slide 137 about precision and bias
- Identifying a gap – the argument is deductively invalid when it is made
- Significance of Slide 48
- The possible deduction process: if the claim is about sample is unbiased – there is a
possibility that it might go wrong. If the sample claims to be the right size, there is a
possibility that this could go wrong. It is
