PLG 310 Chapter Notes - Chapter 8: Walkability, Standard Deviation, Statistical Inference
Document Summary
Week 8 lecture: introductgion to inferential statistics, estimating. When we don"t know the population mean. We will draw one sample, calculate its mean value, and then make an inference about the value of the population mean based on sample"s mean value. Statistical interference: the theory, methods, and practice of forming judgements about the parameters of a population, usually on the basis of random sampling: our interest is in population. We calculate sample statistics and then use the statistics to understand what the parameter might be: objective of inferential statistics: is to use the information contained in the sample data to increase our knowledge of the sampled population. We are using the sample statistic to estimate a population parameter. We collected data from 36 households who live in low income neighbourhoods. The average hh income for another neighbourhood (b) is ,000.
