Statistical significance is the same as practical significance.

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 8 against

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

Is it true that statistical significance is the same as practical significance?

No. Multiple peer-reviewed sources and a reference work state that statistical significance and practical significance are distinct concepts, and one explicitly calls conflating them a common misconception.
