WebDefinition and Properties. 'Bootstrapping' describes a process which aims to estimate how a statistic's value will vary when it is calculated from random samples of an infinite population. To achieve this a model population is constructed from your sample of observations, and resampled so as to mimic how those observations were obtained. WebExamples on Inferential Statistics. Example 1: After a new sales training is given to employees the average sale goes up to $150 (a sample of 25 employees was examined) with a standard deviation of $12. Before the training, the average sale was $100. Check if the training helped at α α = 0.05.
