But, with the example on the left, there is one value to the left of q1. And one is not a quarter of seven. That's something that has always confused me a little.

[@rjblitz5871]

Yes! Likewise. I hoped Eddie would explain this

[@sharonche5042]

Just what I thought!

[@drspin1820]

If you think of the quartiles as cut-off points or checkpoints, the number of values between two cut-offs should be one quarter. So in the first example of 3, 7, 9, 13, 14, 17, 20, the cut-offs are 7, 13 and 17. To the left of 7 is one number, between 7 and 13 is one number, between 13 and 17 is one number, and to the right of 17 is one number. Each makes up a quarter of the data points between cut-offs. In the second example, because your cut-offs are not numbers observed in the dataset, you will be including all 8 data points in the quartering.

Can I know the app you used on your Ipad in the video? It looks convenient.

Being able to explain can be rough. But what's really frustrating is people who can't get simple concepts, or completely forget in 5 minutes. I have repeatedly tried to get some co-workers to deal with "military time". It really is simple: if the time is after noon, just add 12. 1PM becomes 13, 2PM becomes 14, etc. Going the other way, if the number is larger than 12, just subtract 12: 13 becomes 1, etc. But they just can't get it. And don't even get started on decimal hours!

[@goldenwarrior1186]

What are decimal hours?

[@jursamaj]

@@goldenwarrior1186 You know, like 3.5 is 3 and a half. You don't use minutes at all, instead using hundredths of an hour.

Lol. We use that in Europe

Why don’t some people get military time? It’s really intuitive

I recently ran into a problem by accident. I was feeding baby some Gerber Rice Cereal when I spotted the brag on the package: "Iron For Brain Development". So I looked at the nutrition label and it said: 6.75mg per serving; = 60% minimum daily req. So I went to my bottle of iron pills and read that label: 65mg = 361% mdr. So the question arose: What % of the iron mommy needs does baby get? Have at it.

[@goldenwarrior1186]

NEI (looking at it from a purely mathematical perspective). Edit: I reread the comment and think there might actually be enough info to solve it. Too lazy to do the math tho (also I don’t even know what to do to solve it)

[@skinovtheperineum1208]

@@goldenwarrior1186 - That was the point.

[@goldenwarrior1186]

@@skinovtheperineum1208 6.75 is about 10.38% of 65 (wait is that the answer?). Also, 100% mdr would be 11.25 mg
