In order to use data from a sample group to make judgments about an entire population, you will explore probability in order to move toward the area of inferential statistics in this course. You will identify the role of discrete variables, use them in determining probability, find the expected value, and define variance. Additionally, the normal distribution, often called the bell curve, is a practical model for many business measurements, including financial decision making, process variations, and salaries. In this course you will examine the normal distribution and identify how to determine probabilities and percentiles from each of these distributions.
WHAT YOU'LL LEARN
Identify the role of discrete variables and how to utilize them in determining probability
Determine their population mean, known as expected value
Define variance of a discrete variable and calculate it in a practice exercise
Examine the normal distribution, including both the standard normal curve and its siblings with differing means and standard deviations
Identify how to determine probabilities and percentiles from each of these distributions
