24 Confidence intervals for two independent means
So far, you have learnt to ask a RQ, identify different ways of obtaining data, design the study, collect the data describe the data, summarise data graphically and numerically, and understand the tools of inference.
In this chapter, you will learn about confidence intervals for the differences between two means. You will learn to:
- produce confidence intervals for two independent means.
- determine whether the conditions for using the confidence intervals apply in a given situation.
