Course: SkillsCom BA 275 16.0 > Section: Credit Unit 3 Module 1

Throughout Credit Unit 3, you will be learning about confidence intervals. In statistics, a confidence interval (CI) is a type of interval estimate of a population parameter. It is an observed interval, i.e., it is calculated from the observations, in principle from sample to sample, that frequently includes the parameter of interest if the experiment is repeated.

Next, we will be exploring hypothesis testing. A statistical hypothesis test is a method of statistical inference using data from a scientific study. In statistics a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone, according to a pre-determined threshold probability, the significance level.
