This article from Nature is  an excellent primer on the concerns surrounding the use of p -values as the great gate keeper of statistical significance. The article includes historical perspective on how p -values came to be so widely used as well as some discussion on solutions and alternative measures of significance. This article also provides good examples failed attempts at replication (good examples of Type I errors) and a shout out to Open Science Framework folks. Personally, I have revised my class for the fall to include more discussion of and use of effect sizes. I think this article may be a bit above an undergraduate, introduction to statistics class but it could be useful for us as instructors as well as a good reading for advanced undergraduates and graduate students.

This NPR story by Patti Neighmond is about determining the underlying cause of U.S. obesity epidemic. As the name of the segment states, it seems to come down to food consumption and exercise, but which is the culprit? This is a good example for research methods because it describes methodology for examining both sides of this question. The methodology used also provides good examples of archival data usage.

If you are looking for an alternative to using good ol' Excel and SPSS to create graphs and charts, perhaps you students would like to create infographics via a free, online resource. One such tool is Piktochart . It requires registration (via email, Facebook, or Google). It has many free templates as well as a "pro" pay to play package. Below are a few screen grabs of what it is like to personalize one of their templates with your own data. Below, I input a bit of user data from this blog into a pre-existing template. Piktochart template User interface for entering your own data (if you can use Excel, you can use this) End result, with data from this blog It is pretty easy to use, they have multiple different kinds of figures (from good old pie charts and bar graphs to visualizations that stray far from the APA style manual but still do a good job of conveying data to an audience). This coming semester, I am adding a service learning component to my s...

Five.com created an app to predict you score on the Big Five by analyzing your FB status updates. five.com's prediction via status update It might be fun to have students use this app to measure their Big Five and then compare those findings to the  youarewhatyoulike.com app ( which I previously discussed on this blog ), which predicts your scores on the Big Five based on what you "Like" on FB. youarewhatyoulike.com's prediction via "Likes" As you can see, my "Likes" indicate that I am calm and relaxed but I am a neurotic status updater (crap...I'm that guy!). By contrasting the two, you could discuss reliability, validity, how such results are affected by social desirability, etc. Furthermore, you could also have your students take the original scale and see how it stacks up to the two FB measures. Note: If you ask your students to do this, they will have to give these apps access to a bunch of their personal informat...

I am busy prepping my statistics class for the fall (as well as doing a bunch of stuff that I should have done in June, but I digress). Most of my students are required to take statistics and are afraid of mathematics so I'm going to try to convince them to embrace statistics by showing them that more and more non-statsy jobs require data collection, data analysis, data driven decisions, program assessment, etc..  I find that my students are increasingly aware of the current job market as well as their student loan debt. As such, I think that students are receptive to arguments that  explain  how even a little bit of statistical knowledge can make them more attractive to potential employers. Here are some resources I have found to do just that.  This article by Susan Adams for Forbes lists the top ten skills employers are looking for in employees. Included in the top ten: "2. Ability to make decisions and solve problems 5. Ability to obtain and ...

The folks of TED have created ed.ted.com , a website that allows you to use their videos (or any video available via youtube) and create a lesson around the video. You can create an assessment quiz (and save your student's grades on the assessment). You can also create discussion boards and post your own commentary/links related to the content of the video. I know, right? There are several lessons that relate to statistics and research methods . Here is a shorter video that teaches the viewer how to assess  the quality of medical research , and here is a list of TED talks about Data Analysis and Probability  While the teaching of statistics and research methods are my jam, you can use any old video from youtube/TED ( like the many talks featuring psychology research ) and create an online lesson and assessment about the talk. Pretty cool! I think these could be use as bonus points, a quick homework assignment, and as a way to reiterate the more conceptual ideas surroun...
