Two Events: Multiplication Law

christoff — Thu, 29 Mar 2012 00:15:57 +0000

A quick overview of the multiplicaiton law used in probability. There is a pretty nice little java applet to help you visualize the math.

Receiver Operating Characteristic Curves: an Introduction

christoff — Wed, 05 Oct 2011 01:01:33 +0000

This might be a little more than just an introduction into ROC curves. This specific lecture goes over statistical sensitivity, specificity, false negative fractions and false positive fractions and how they all work together in making a ROC curve. The other benifit of this lecture is that it does so in a medical sense, which will be benefitial to biostatistic majors and medical students.

Scientific mind map software (free)

josh — Wed, 22 Jun 2011 05:24:45 +0000

It's time for me to come clean: I'm a total mindmap junkie. Someone turned me on to the phenomenon a few years ago and it didn't quite click but in the last year, I've been unstoppable. I find it to be the easiest way to visaulize a topic from top to bottom and helps me to construct a complete picture of any topic. You can use them like a to-do like or you can plan out an entire master's thesis.

I use Mind Node for Mac but tried this out and saw the potential for folks in the research world. Give it a try and comment below if you found it useful for your studies, writing, or otherwise.

Mathematical function graphing software program

josh — Wed, 22 Jun 2011 05:16:04 +0000

This is a freeware math function graphing software that can plot "2 dimensional, parametric, polar, and 3 dimension functions" but only in Windows XP, Vista, and 2003. It looks like a useful program if you're able to run it and you've got to give the guy credit for a completely comic-sans website.

p-Value Calculator for the Chi-Square Test

josh — Wed, 22 Jun 2011 05:06:36 +0000

From the site:

This calculator will tell you the one-tailed probability value of a chi-square test (i.e., the area under the chi-square distribution from the chi-square value to infinity), given the chi-square value and the degrees of freedom.

Chi-Square Value Calculator

josh — Wed, 22 Jun 2011 05:01:27 +0000

From the site:

Computes a chi-square value, given the probability and the degrees of freedom.

One-Way ANOVA from Summary Data

josh — Wed, 22 Jun 2011 04:57:51 +0000

From the site:

This calculator will generate a complete one-way analysis of variance (ANOVA) table for up to 8 groups, including sums of squares, degrees of freedom, mean squares, and F and p-values, given the number of subjects, mean, and standard deviation for each group.

ANOVA Intraclass Correlation Calculator

josh — Wed, 22 Jun 2011 04:56:33 +0000

From the site:

This calculator will compute the intraclass correlation for an analysis of variance (ANOVA), given the between-groups mean square, the within-groups mean square, and the number of subjects in each group.

Search and upload theses and dissertations

OpenThesis is a place to upload your thesis for everyone else to read and use. Looks like a great resource for students who need a little help getting through the hardest part of a grad degree. From the site:

OpenThesis is a free repository of theses, dissertations, and other academic documents, coupled with powerful search, organization, and collaboration tools.

Y-intercept and the slope of a line

Video from the Khan Academy on line slope, y-intercepts, and how they're related.

3rd degree polynomial coefficient problem

Great video from the always-helpful Khan Academy!

Publishing your research 101

christoff — Tue, 10 May 2011 19:49:18 +0000

This is a great video on the process of having your research published. This is great for undergraduates and graduate students who are starting with their own research.

Best advice: Make writing a part of the research and start early.

When should you begin to think about writing up your research for publication?
How do your students handle your approach of writing while you research?
How do new technologies help scientists communicate their work?
How many drafts does each paper undergo? Do you have your papers undergo an internal review?
Do authors need to be thinking of marketing their articles?
How concerned should I be about the title and abstract of my papers?

Great calculus video tutoring.

All you ever wanted to know about Pascal's triangle

gsadmin — Tue, 19 Apr 2011 18:25:43 +0000

I realize this might be better suited for the Math section but since pascal's triangle has a micro-implementation in NMR spectroscopy I thought it might be somewhat interesting. There is a lot of information on this site about pascal's triangle.
