Confidence Intervals

In this lesson, we will learn confidence intervals. We will understand point estimate, margin of error, confidence level, standard error, and how a population parameter is estimated as an interval using sample data through practical examples. ## Lesson objective In this lesson, we will learn confidence intervals. In the previous lesson, we covered sampling and sampling distributions. We learned population, sample, representative sample, sampling bias, sampling error, standard error, and Central Limit Theorem. Now we will learn how to make better conclusions about a population based on a sample. In real data analysis, we often do not know the full population.
