WEEK 2 It can, therefore, be thought of as a random variable, whose properties can be described with a probability distribution. The variance and standard deviation are closely related to each other; the standard deviation always equals the square root of the variance. Topics covered include If this process is carried out correctly, each sample should accurately reflect the characteristics of the population.

In statistics, the mean, median, and mode are known as measures of central tendency; they are used to identify the center of a data set: Mean: The value between the largest and smallest values of a data set, obtained by a prescribed method. Business tendency in manufacturing, construction, trade and services - October 2020 A A A. We then introduce various calculations to constructing confidence intervals and to conduct different kinds of Hypothesis Tests. The specialization will be at an introductory level. This module presents various business applications of the confidence interval including an application where we use the confidence interval to calculate an appropriate sample size. The process for computing this is exactly the same; you add up all the elements in the sample and divide by the size of the sample. Regression Analysis is perhaps the single most important Business Statistics tool used in the industry. Check with your institution to learn more. This module introduces Hypothesis Testing. This module presents the covariance and correlation measures and their respective Excel functions. To successfully complete course assignments, students must have access to Microsoft Excel. As such, you should narrow down your topic to something more focused. If you have taken a statistics course in the past, you may find some of the topics in this course familiar. Here, an extreme test statistic is one that lies outside the bounds of the critical value or values. • Use of Pivot tables with categorical as well as numerical data • Introducing the t-distribution, the T.DIST and T.INV excel functions Learners are introduced to the IF, nested IF, VLOOKUP and the HLOOKUP functions of Excel.
