PHIL 12 Chapter 5, 6, 7: Imprecision and Confidence Level & Statistical Relations & Correlations Described
Document Summary
Phil 12 textbook notes chapter 5: imprecision and confidence level & chapter 6: 5. 2 imprecision: a more precise conclusion is less likely to be true than a less precise one, the less information there is in a claim, the more likely it is to be true. 5. 3 some technical terms: sample size: amount of things you are observing, observed frequency: proportion of a property in a sample, margin of error: range of possibilities observed around the frequency; expressed as a decimal +/- 5. 4 confidence level: confidence level: probability of the truth of a claim. 5. 5 how to pick a confidence level: usually 95% 6. 2 standard deviation: one standard deviation: 67% level of confidence, two standard deviation: 95% level of confidence, three standard deviation: 99% level of confidence. 7. 1 proportions and correlations: proportion: a percent, correlations: difference between p and q in the population, positively correlated: proportion of p is larger than the proportion of q among the population.
