When planning an experiment, do you usually decide on the statistical analysis before collecting the data, or after seeing what the data look like?

Curious how this is usually practically handled.

How do experimental life scientists usually decide which statistical test to use in practice?

For a given dataset, more than one test may satisfy the statistical assumptions and align with the hypothesis being tested.

Curious how this varies across labs and fields.
