The ranged typically from 10^5 to 10^7 copies of gene (ABC), (DEF), or (XYZ) in a particular environment, so even log transformed, the values range from 4.xx to 7.xx<br /><br />And while SAS is great at doing analysis ... I'm not too fond of the lengths I need to go to to get that data. *grumble*<br /><br />PS: Saw your comment over at The Big Stick. Next time I'm in DC I'll drop you an email and we can meet for lunch or something.Tomhttps://www.blogger.com/profile/14211618861743447072noreply@blogger.comtag:blogger.com,1999:blog-38049554.post-78529373496312878542010-03-18T07:45:09.364-05:002010-03-18T07:45:09.364-05:00What - you're rebelling against SAS-Graph? Oh...What - you're rebelling against SAS-Graph? Oh the burn . . . <br /><br />Ok, back to reality. I htink box and whisker is an excellent choice for ranges of data over a population wher eyour results don't trend to zero (so your right hand figure). IF they do trend to zero, or you have data skewed to zero one way or the other, then they aren't as descriptive because they won't do as good a job of showing Standard Deviation or anything like that.Philip H.https://www.blogger.com/profile/12049875206738422083noreply@blogger.comtag:blogger.com,1999:blog-38049554.post-81993232748094622222010-03-16T11:39:40.984-05:002010-03-16T11:39:40.984-05:00Good points soil mama, and I have nothing to hide!...Good points soil mama, and I have nothing to hide! B&W plots for me (and I did log transform my data before doing my statistics). We use SAS for our statistics, but their graphing options stink so I splurged for Analyze-It! :)Tomhttps://www.blogger.com/profile/14211618861743447072noreply@blogger.comtag:blogger.com,1999:blog-38049554.post-71922162669391785342010-03-16T11:24:09.591-05:002010-03-16T11:24:09.591-05:00I'm also working on a manuscript that will inc...I'm also working on a manuscript that will include some QPCR data. I was looking to see how others have presented it and it's nearly all normal bar charts or tables. I get what you're saying about the bar chart seeming misleading by shading in the whole area, but I think most people still just look at the mean and error bars. <br />one reason why people probably don't present box plots is that it shows the "shape" of the data and it would be really obvious if it has a normal distribution or not. I know for a fact that many folks in our field don't know jack about stats and don't log transform before doing stats, even when their data doesn't fit normality assumptions of the statistical test. If they were to present box plots, then it would be very obvious that they didn't do the stats right. I've also found that some people are just presenting means and SE and not even doing stats on QPRC data.<br /><br />soo, I think you could/should go for the box and whisker plots. I think it's similar to soil enzyme data where most people do standard bar charts, but some do box plots since they like them better. Just be aware that if your data doesn't look pretty is will be much more obvious with the box plots.<br /><br />*I use SigmaPlot :)soil mamahttps://www.blogger.com/profile/01893750762515926957noreply@blogger.comtag:blogger.com,1999:blog-38049554.post-18063165973696329022010-03-16T10:42:46.110-05:002010-03-16T10:42:46.110-05:00I'm pro-G&W plot.
