Reliability is all about consistency. If different methods are used to measure water, it would

Each can be estimated by comparing different sets of results produced by the same methods.”
The types of reliability are: 1. Test-reset, 2. Interrater 3. Parallel forms and 4. Internal
consistency (Middleton, 2019).
Now we will look at the different types of individually.
