Talk:Stemplot

From Wikipedia, the free encyclopedia

[edit] Error

Somebody needs to check the math. I've always heard stemplots are to be rounded down to the nearest integer, yet in all the examples standard rounding principles (0-4, 5-9) are used. Again, someone with more math knowledge then me please check that out. I'm looking at a business statistics book right now and it's telling me to round down...

And Kareeser, the point of a stemplot is to sort data so that it can be anlyzed quicker. It was mainly used prior to computers and spreadsheets, but it is still an easy way to sort simple data into a more coherent and easier-to-read format. Rykoshet 1:50 Oct 1 2007 (EST)

[edit] Comments

Fairly good article on describing what a stemplot is and how to construct one, but what is its use? I am still slightly confused. Kareeser|^Talk! 19:00, 11 September 2006 (UTC)

I've added a section on their advantages and disadvantages. Richard001 00:11, 11 March 2007 (UTC)

[edit] Error for negative stem

The second plot (one with the negative values) has omitted -3.4. I do not know which one of these two possible solutions is correct. Also, would negative numbers be sorted by absolute value, or by their actual value?
