- Evaluating the use of Evidence
- Sample size
- the smaller a sample size the less reliable - a sample size of around 1000 people is very accurate.
- Representatives
- A sample of data needs to represent everyone in a communtiy - every race, gender, religion, age etc...
- Circumstance of Data Collection
- If data is not carefully collected it is less reliable. - the most reliable evidence is collected by professional collectors in controlled conditions
- Generalisability
- for data to be reliable it should be collected resently and should be relevant to a location, situation or types of people being discussed
- Ambiguity of Findings
- The way that data is used - Ambiguity - there is more than one possible meaning
- Interpretation of statistics
- the use of averages can give a misleading impression - have the statistics been averaged - ie has the mean, median, mode or range been used
- Sample size
