In Lessons 2 and Lesson 3 you learned about descriptive statistics. Lesson 4 begins our coverage of inferential statistics which use data from a sample to make an inference about a population. Confidence intervals use data collected from a sample to estimate a population parameter. One quantitative variable is covered in Sections 2.2 and 2.3 of the Lock 5 textbook. In these sections, you will learn how to describe the distribution of a quantitative variable in terms of shape, central tendency, and variability. You will be introduced to the normal distribution, z scores, percentiles, graphs, and the five-number-summary.Sampling Distribution for a Proportion. Choose samples of size n =. Generate 1 Sample.
