A simple tool operationalizes post-childbirth hemorrhaging and saves lives.

I love it.  Here is a link to the original study . I learned about it from an NPR story about the research by Rhitu Chaterjee . I also love it because it is an accessible example of a bunch of statistics things: Dependent variables...operationalizing variables...why cross-cultural research and solutions aren't just lip service to diversity...how control groups in medical research are very different than control groups in psychology research...absolute vs. relative risk. -Dependent variables/operationalized variables: This study clearly illustrates the power of measurement and operationalization. The researchers wanted to create a way to better assess post-childbirth h...

CDC Mental Health Data

It shouldn't come as a shock that the CDC shares data on rates of public health issues in the US.  However, you may be unaware of the available data and interactive visualizations provided by the CDC and the different ways you can use them in class . 1. Teach your students a lesson about good sources for mental health data. 2. Show your students how data visualizations can help present and simplify complex data. https://www.cdc.gov/nchs/covid19/pulse/mental-health.htm 3. Get into the research methods. Everyone has heard of the census, but fewer have heard of the Household Pulse Survey (https://www.census.gov/data/experimental-data-products/household-pulse-survey.html). The US Census collects much information between the 10-year census, including mental health data. https://www.census.gov/data/experimental-data-products/household-pulse-survey.html 4. Talk about how the government assesses depression and anxiety. For example, you can show how the basic methodology uses a valid, relia...

MCU regression, revisited

I think it is important to emphasize how regression can be used to make future predictions using trends in existing data. Most psychology books use psychology examples to illustrate this, which makes sense. Still, I think explaining how regression is widely used in business to make financial decisions, and predictions is important. But that can be boring. But I found one example that uses the Marvel Comic Universe to do this. I already blogged about this , but I'm sharing exactly how I used this in class presently. ASIDE: This data is being regularly updated! Here is a Google Drive folder with 1) my version of the data (CSV and I turned all the percentages to decimal points for JASP) and 2) my PPT . Which includes photos of the scientists of the MCU. ALSO: While your students are doing their exercise, totes play the soundtrack from Guardians of the Galaxy. Do it. 

A rank ordering of the Taylor Swift songbook.

File under: End of the semester stress blogging about a person who brings me joy. Taylor Swift (see: sampling error with Taylor ). Here is a new, VERY accessible example of ordinal data . Rob Sheffield, writing for Rolling Stone, rank-ordered ALL of Dr. Swift's songs.  https://www.rollingstone.com/music/music-lists/taylor-swift-songs-ranked-rob-sheffield-201800/bad-blood-2014-196114/ Also, introduce your students to Methods Section 😁. This rank order is based on the variable "Taylor genius". You could even use this as an example of anti-interrater reliability. This ranking comes from exactly one person. AND YOU'RE ON YOUR OWN KID DESERVED BETTER. Each ranking includes the best lyric from the song as well as a brief description of the Taylor Genius on display. Is this also an example of qualitative data? https://www.rollingstone.com/music/music-lists/taylor-swift-songs-ranked-rob-sheffield-201800/the-great-war-2022-1234617639/

1,200 years worth of cherry blossom bloom data from Kyoto, Japan.

It is April 18 in Erie, PA. It sleeted yesterday at my kid's soccer game. However, I know in my heart that Spring is coming. Every year, I get excited about the first crocuses and daffodils here in NW PA. Due to these hard winters followed by beautiful (if snowy) springs, I feel a certain kinship for the Japanese spring lovers who have been tracking the date of the cherry blossom blooms in Kyoto, Japan, for the last 1,200 years. Well, it hasn't always been tracked by humans; sometimes, modern humans have extrapolated this data. I'll get to that in a second. I learned about this data from Twitter user Robin Rohwer . She created this visualization for the data: https://twitter.com/RobinRohwer/status/1639097356657512449 She also shared where she found this data via NOAA , via  Yasuyuki Aono's website: http://atmenv.envi.osakafu-u.ac.jp/aono/kyophenotemp4/ . Go to the NOAA website and poke around. You can see notations referring to how the data was extrapolated over time an...

Want to avoid federal regulation and increase profits? Just don't share your data.

TL;DR: One way to avoid government regulation is by simply refusing to share data that may lead to government regulation (and safer trains). I'm looking at you, railroads. _____________________________________________________________________________ Not every example I post syncs directly to the typical Psychological Statistics curriculum. I also post about statistical literacy. Like why data matters and counts. And how very, very simple data could help illuminate and solve real-world problems, but only if we can access that data. I get good and mad at organizations that avoid responsibility by manipulating and/or withholding data.  See: Organizations that  share data but in a functionally inaccessible way. Also, I created a spreadsheet (of course I did) containing several examples of times when large organizations goofed around with data so they wouldn't get sued. It looks like I should add rail roads to this list. Aside: I grew up not 10 miles from the world-famous Horsesho...

Sampling Error (Taylor's Version)

Friends. You don't know what finding fun stats blog content has been like over the last few years. All of the data writers/websites I followed were always writing about, explaining, and visualizing COVID or political data (rightfully so). I prefer examples about puppies , lists of songs banned from wedding reception s, and ghosts . Memorable examples stick in my students' heads and don't presuppose any knowledge about psychological theory.  Due to the lack of silly data and my own life as a professor, mom of two, wife, and friend, my number of posts during The Rona definitely dipped.  But now, as the crocuses bloom in Erie, PA, the earth, and I, are finding new life and new examples. Nathaniel Rakich, writing for FiveThirtyEight, wrote a whole piece  USING TAYLOR SWIFT TO EXPLAIN POLLING/SAMPLING ERROR S. Specifically, this article tackles three different polling firms and how they went about asking Americans which Taylor Swift album is their favorite Taylor Swift album....
