The "data" (the unknown variables) always varies. That's why you need n >> 1 in A/B tests. And you are only testing one variable: the asking price.

Thanks, though what does "n >> 1" mean?

(Ask since to me it reads as gibberish and there's no way to Google it myself.)

Usually this notation ("x >> y") means "x much larger than y," so you need way more than 1 person to A/B test.

Thanks. Normally need more few thousand to do a valid A/B test; meaning to me the comment makes no sense.

[Karunamon → saycheese]

You need more than one person to A/B test against, so n in this point is sample size.

"much greater than"

[brianwawok → matt4077]

Correct. Running a e-commerce store each buyer buys different items. You need a big n.

What is a "big n" mean?

(Ask since I'm used to running valid A/B test on groups in the 1000s.)
