Document Summary
Chapter 9: the distributions of sample statistics: descriptive statistics the focus is on summarizing and presenting info. Finding measures of location and variation, making charts and tables, and assess the distribution of the data. It"s (cid:374)ot possible to measure the number of km each canadian walks every day. So, i randomly choose a sample of 10 people in canada and record how far they walk on average on a given day. Then, i randomly choose another group of 10 people and measure their average daily walking distance. I repeat this process 5x and each time i record the average daily walking distance for each group. Each sample has its own average walking distance. I can continue this experiment of selecting random people and measuring their average walking distance to observe the pattern of sample means. This pattern is the sampling distribution for the average number of km canadians walk on a given day: remember: sample size (n) is different from.
