The aims of statistics are to provide methods of drawing valid inferences from samples. A major preoccupation of modern statistics is deciding what degree of reliance can reasonably be placed on particular samples. This course introduces these basic concepts. The foundational role of sampling, regression and hypothesis testing. In the mid-eighteenth-century statistics was the study of States - their populations, industries, natural advantages, and so forth. The course aims at familiarizing the students that Statistics is the science of learning from data to make an inference about a population of interest. Understand the concept of the sampling distribution of a statistic, and in particular describe the behavior of the sample mean. understand the logic and application of hypothesis testing and interpret a set of descriptive statistics and understand the limitations of each measure. To apply the appropriate inferential statistical technique to situations of questions, interpret the results of an inferential test and understand the limitations of each procedure, and compute descriptive and inferential statistics using a calculator and computer.
