Do bear in mind that 250k is the total number of receipts they have. The number of receipts with gaming related purchases are much lower. For example, last year only 1.1% of their total sample made a gaming related purchase.

 

We dont know the number this year but if we apply that same percentage then it would mean that less than 3,000 of the 250,000 made a gaming purchase and were counted above. 

People already posted the fine print that only 2000 receipts were game related... no info on how many HW receipts, maybe even less than 500. So I have quite the hard time believing on their precision.

1. that was last year or the year before, when the overall sample was just 150k
2. this is a further proof, that theire sample size is quite decent. if 90% of all receipts would be game related, theire sample size would be screwed towards gamer and way more unreliable.

as said earlier if you want to do a good preliminary election poll, you don't want 100% political interested people. you wan't 40-50%. just like the average country.
it's never about the sample size. 2000 is totally fine for statsitics. it's about the sample itself
