Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Observing a double slit experiment changes the result?

Unclear. Several reference and forum sources state that detecting or observing which slit a particle passes through destroys the interference pattern, changing the measured result. These are explanatory and interpretive accounts rather than a single primary experiment, so they cover the claim only in part.
