# Talk:892: Null Hypothesis

If you get a 50% discount at two shops and buy stuff from both of them, you have a 100% discount. Math. That's how it works, bitches. Davidy²²[talk] 10:05, 9 March 2013 (UTC)

I would feel entirely justified punching someone who said that unironically. Pennpenn 108.162.249.205 00:59, 27 January 2015 (UTC)
I mean, if the two items cost the same, then you would technically get a 100% discount on one. Beanie (talk) 13:31, 30 April 2021 (UTC)

That's a misleading thing about percentages. Like this: Prices of coffee increase by 2% this year, then by 3% next year. That's a 1% increase between years, or a 50% increase between years (from 2 to 3). So which is it? 1 or 50? 141.101.98.240 08:26, 18 December 2013 (UTC)

It's a 50% increase and an increase of 1 percentage point. There's a difference between the two. 162.158.158.235 16:37, 23 April 2020 (UTC)

That's why they've invented the "base points" in financials, to denote the percentages of percentages. It's 1% absolute but 50bpp (base point percentage). 108.162.246.11 18:35, 20 January 2014 (UTC)

Oh really. If you say it increased by 2% this year, then by 3% next year. It increased 3%. Unless you mean it will increase by 3% from LAST YEAR to NEXT YEAR. Then it really increased by 2% then .97%. But for this purpose let's throw that out and make it simple. It increased by 2% this year, and will increase by 3% next year. 50% isn't how much it increased, but how much the increase increased. That's called acceleration. The rate of increase per year is always 2 or 3%. So, 1% doesn't factor into this equation at all no matter how you do the math. The answer is 1.02*1.03. It increased by 5.06% over the last two years. 108.162.216.114 14:59, 18 August 2014 (UTC)

Don't these discussion points belong in a different comic? Or perhaps the garbage? Except (1), he lol'd me. 108.162.219.58 21:23, 5 February 2014 (UTC)

They should be on 985: Percentage Points or 1102: Fastest-Growing --Pudder (talk) 11:35, 23 October 2014 (UTC)

Every time I learn what the null hypothesis is, I forget about it by the next day. I guess my brain is trying to organize the information and it thinks the /dev/null/ folder would be a good place for it. 172.69.58.152 21:17, 26 March 2024 (UTC)
