R Programming for Statistics and Data Science - Standard Error and Confidence Intervals

The video tutorial explains the difference between population and sample data, emphasizing the use of sample data to estimate population parameters. It introduces the concepts of standard error and confidence intervals, explaining their roles in determining the accuracy of sample estimates. The tutorial also covers how to interpret confidence intervals and the significance of standard error in statistical analysis. The lesson concludes with a transition to hypothesis testing.
