## neverforgetvivistee 4 years ago in box and whisker plots, do you draw a line to the outliers (as your whisker)?

1. neverforgetvivistee

or do you just plot a point, but don't draw a line to it?

2. Sigsauer54

Yes You Do

3. Sigsauer54

You draw lines to both outlier points, single lines, not dotted

4. neverforgetvivistee

5. neverforgetvivistee

i mean lower extreme and higher extreme

6. Sigsauer54

No, outliers are first and last numbers

7. neverforgetvivistee

not quartile

No, the whiskers only extend so far and outliers may be single solitary points

10. bob06

is it just me or is this kind of solving this question somewhat of a pain

11. neverforgetvivistee

so you don't draw lines to the outlier?

12. Sigsauer54

See the picture, the ihghest and lowest number, also known as extremes, get points on them and lines drawn to them

13. neverforgetvivistee

but the outliers, like ones that are way lower than the low quartile or way higher than the high quartile, do you draw lines to those? Those are the lower and higher extremes

14. jim_thompson5910

It depends how far the outlier is, but the whiskers will not always connect

15. neverforgetvivistee

how far is too far for the outleir? like 1.5 times the interquartile range right?

16. jim_thompson5910

yeah that sounds right (I'd need to look it up), but take a look at something like this http://media.texample.net/tikz/examples/PNG/box-and-whisker-plot.png

17. neverforgetvivistee

ok thanks, that makes sense now :)

18. jim_thompson5910

you'll see that the outliers are on their own
