In a coin toss, the probability of heads is taught to be half. Is it really? In this preprint, I argue that helping students understand statistics better entails explicit and sustained inclusion of the observer-relative reality of randomness in your pedagogy. #education #STEM doi.org/10.35542/osf...

"Absence of evidence is not evidence of absence." Comprehending this one statement can clear up a host of misunderstandings about how null hypothesis testing works and why failure to reject the null hypothesis does say less than rejecting it. doi.org/10.64628/AAI...

The idea of "Wisdom of the Crowd" may seem strange at first glance, until you realize that the historical foundations of the Gaussian distribution is based on observations of human measurement error. Then, the idea becomes quite... Normal. #Statsky #statistics #edusky

"Association does not imply causation" is the truth and continues to be an important mantra in the practice of statistics. What does it actually mean? Can we prove causal relationships using observational data? If no, does it mean that detected associations are useless? #statssky #causalinference

Join me on 10/18/25 as I talk about ubiquitous bias for publishing statistically significant results in peer-reviewed journals and why it's not the boogeyman it is made out to be. The event is virtual, free and hosted by the R Users Group - PH. Register now! #science www.meetup.com/r-user-group...

Happy to share that one of my most enduring insights from over two decades of teaching statistics and mathematics subjects is now published in Statistics Teacher by @amstatnews.bsky.social. #statsky #STEM #STEAM #education #mathed #iteachmath www.statisticsteacher.org/2025/09/25/p...

All parents want the best for their child. Thus, the issue on Tylenol use & autism risk is so consequential. It's important to communicate the science objectively, thoroughly & compassionately.

There are many “statistically significant” birthdays in August, including the term “artificial intelligence,” coined in August 1955. Read about more historical happenings in August’s This Month in Statistics History: magazine.amstat.org/...

Curious how #publicationbias shapes scientific record? This Shiny app shows hypothetical distributions of published papers across levels of bias. Play with assumptions on the research landscape and how researchers behave to see what happens. #science #statsky #bias levelalpha005.shinyapps.io/shiny1/

In this paper, I discuss an often misunderstood aspect of inference that can trip up even seasoned researchers. If you wonder what "practical significance" means in #statistics, I guarantee you that reading this will make you a better scientist. #statsky #StatsSky #science doi.org/10.1093/jrss...

Off to Nashville for the Joint Statistical Meetings. #jsm #jsm2025 #statsky. Doing a talk on our paper about some new disaggregated displays and measures for comparing continuous quantities between groups. Wish me luck!

Published studies often show more significant results than unpublished ones. Is this bad practice by journals? Not really. Read why in my latest paper published by @tandfresearch.bsky.social #sciencesky #statsky #researchsky #science #statistics #bias #research www.tandfonline.com/doi/full/10....

No method is perfect; no assumptions hold exactly. We use #statistics to make sense of uncertainty as objectively as we can. Most importantly, proper statistical practice keeps us honest, especially when results don't conform to what we hoped for. #datascience #statsky #dataliteracy #science #edusky

Congratulations to the finalists of Significance Magazine's Statistical Excellence Award for Early-Career Writing!

Statistical power is the chance of detecting an effect given that a specific one exists. Being transparent with how much power we can get for a study before spending resources on it gives confidence to funders that their money is not being spent on a coin toss. #academicsky #research #science #STEM

Our latest paper is now published in @jrssa.bsky.social. We constructed new ways to describe disparity between groups in survey-weighted data. Software to use these methods are now available in the glorenz R-package. #statsky #datascience #dataliteracy #academicsky academic.oup.com/jrsssa/advan...

Hoping the role shifts more towards genuinely enlightening the lay public about statistical principles and how they inform policymaking. Now more than ever, there is opportunity to bring a higher level of #dataliteracy to our youth, especially to those who won't enter #STEM. #statsky #datascience

In #ABAtherapy, children with #autism who accomplish a task at 80% mastery criterion do not necessarily have 80% mastery level. #BCBA and researchers can now use the miebl R-package to better contextualize criterion choices in discrete trial training. #ABA cran.r-project.org/web/packages...

My 1st paper in 2025 published by @springernature.com is so close to my heart. As a parent of a child w/level 2 #autism, I hope this work will help #ABAtherapy practitioners & researchers in their tireless efforts to help kids like my Mabel be the best they can be. link.springer.com/article/10.1...

Every teacher needs to ask themselves: "Knowing that my students have easy access to gen #ai after class, how can I develop my pedagogy to maximize the value of this resource for them?" It won't be easy, but it can be glorious. #edusky #academicsky #EdTech #Educhat #K12 #EduSkyAI #Edchat

You can interrogate data ceaselessly until it confesses but remember that at that point, it will just tell you whatever it was that you wanted to hear. Learning #statistics is knowing better than to fool oneself. #datascience #edusky #statsky #dataliteracy #iteachmath art by @bonkerific.bsky.social

In addition, if you love any #science, taking courses on 1.) the fundamentals of statistical estimation and inference and on 2.) specific methods commonly used in your field will make you a much better scientist regardless of your major. #edusky #statsky #academicsky

This was in the 60's. Now kids have TI calculators & apps like Desmos as part of math class. A similar thing is happening now with #ai, but this time on writing instead of computing. As before, #education must adapt to prepare students for their future, which includes ai tools. #edusky #iteachmath

On this day, the brilliant statistician responsible for many tools we still use now (ANOVA,MLE,Exact Tests, etc.) but most importantly for popularizing significance & p-values, was born. Sir Ronald Aylmer Fisher FRS (17 Feb 1890 – 29 Jul 1962). #statsky #datascience #statistics #pvalue #significance

Imagine having one of them shoot a target for you. You're not allowed to see whether they hit the target or not but you are required to decide on whether or not you think the target was hit. What decision will you make? Why? What statistical concept did I just explain? #edusky #statsky #iteachmath

Remember that in #statistics, there’s a world of difference between setting out to find if two things are different and not finding enough evidence that they are, and setting out to find if two things are the same and finding enough evidence that they are. Never mistake the former for the latter.

My kid was telling me earlier how glad she was that she didn't have to deal with geometry anymore (she took it last year) and that advanced algebra is way more fun. We both like Marvel movies (me more than her), so I just sent this to her on discord:

Think of how much sleep you typically get. Decide to stop looking at screens an hour before bed. Collect data on your sleep in this new setting. From 0%-100% how close is this new sleep experience to before you reduced screentime? That's basically a p-value. #edusky #statsky #datascience #iteachmath

One of the things I live by as a teacher: don't test what you didn't teach. Obviously, this doesn't mean that our examples should be the exact items we include in our exams, but we should be mindful about how much the complexity of our test items depart from our examples. #edusky #iteachmath #STEM

Handwashing wasn't #commonsense until the 1840's, when Ignaz Semmelweis showed it drastically reduced puerperal fever incidence among new mothers. Even then, it faced resistance, and took decades of more #science from Pasteur and Lister to be accepted by the public. Do you wash your hands? #edusky

Public health policy initiatives made today can take years to produce enough data to measure impact. This makes competence and #integrity of decision makers ever critical. All decisions carry uncertainty, but each one needs to be made with the best information and a clear conscience. #publichealth

The statistician’s #paradox: Without uncertainty, there is no need for statistical inference, but a lot of critiques against statistical inference seem based on the notion that tools in #statistics should enable decision-making with certainty. #datascience #edusky #statsky #dataliteracy #academicsky

Keep in mind that on their own, point estimates are virtually meaningless. Average hourly income for Job A [11, 10, 11, 9, 9] = $10 Average hourly income for Job B [5, 5, 5, 5, 30] = $10 Average hourly income for Job C [0, 0, 0, 50, 0] = $10 #iteachmath #statsky #dataliteracy #datascience #edusky

DO adjust when you are exploring many different candidate signals (e.g. SNPs) and are interested which of them might be significant. DON’T adjust if you are hypothesizing a model with one primary variable of interest and a ton of confounders. #researchsky #academicsky #science #statsky #datascience

If you’re worried about #ai use in your course, I submit that your focus shouldn’t be on guarding against ai use in your assessments but on revising assessments so that they can still measure desired learning outcomes in a world where students use ai. #edusky #academicsky #education #academicchatter

At alpha=0.05, the probability that two independent studies on the same topic will both make a type 1 error is 0.0025. That illustrates how important even a single replication study is in improving the credibility of a discovery. #science #researchsky #academicsky #statsky #datascience #dataliteracy

Indeed, a lot of money is often needed to do great things in #science. However, not all science needs funding to be worth doing. It might not have much impact, but satisfying one's curiosity and sharing it with others is good for the soul. #academicsky #researchsky #academicchatter #researchlife

That time when a study studied if studies on positive publication bias were subject to positive publication bias. 😆 (imo, results look lackluster with only 26 studies and I disagree with some aspects of the interpretation, but this idea is quite fun). #science #researchsky #academicsky #bias #edusky

Some fun with gganimate. Graph shows journal articles in a hypothetical world where 80% of null hypotheses studied are true, studies have good (80%) power, & publishers have no positive bias. Do you like this world? How close/far are we from it? #statsky #edusky #academicsky #researchsky #iteachmath
