In inferential statistics, we are generally using a sample. When the sample size is small, the estimation and testing procedures of Chapter 8 are not appropriate. Remember there is variability among samples- they might seem to come from different populations but they may not.

Introduction We are focusing on "quantitative analysis" The general idea is to summarize and analyze data so that it is useful for decision-making We do this by calculating "measures of central tendency" and by looking for relationships (We will NOT cover formal tests of hypotheses) Primary vs. secondary data sources Data on uses Blackwell Scientific Publications, Oxford. Standard Error Standard error of the mean Standard deviation / square root of (sample size) (if sample greater than 60) Standard error of the proportion Square root of (proportion X 1 - proportion) / n) Important: dependent on sample size Larger the sample, the smaller the standard error. Standard error measures the precision of the estimate of a population parameter provided by the sample mean or proportion. This course The Physics of systems containing, Classical Newtons Laws ?? More than one method is . Introduction Observational Data Descriptive statistics involve summarizing a collection of data. A very large study might find that a difference of .1 on a VAS Scale of 0 to 10 is statistically significant but it may be of no clinical significance A large study might find many significant findings during multivariable analyses.
