On Saturday August 25, 2018 at 8:08 PM I finally hit Inbox Zero! Inbox Zero I did it by immediately copying the snippets of email I wanted into Evernote notes (my notetaking system). I also attended to to-dos more immediately, or added them to a note of “To-Dos”. I doubt I will stay at zero emails in my inbox, but I have been at fewer than 10 emails all summer.

I am giving a talk at the 46th Annual Meeting of the Statistical Society of Canada in Montreal on June 05, 2018. The talk is part of an invited session on Teaching Statistics to Graduate Students in the Health and Social Sciences. Information, including the slides, is available below. Title: Statistical Computing: Non-Ignorable Missingness in the Graduate-Level Social Science Curriculum Abstract: In 2010, Nolan and Temple Lang pointed out that "computational literacy and programming are as fundamental to statistical practice and research as mathematics".

R Markdown is a great way to integrate R code into a document. An example of the default theme used in R Markdown HTML documents is shown below. Pre-Packaged Themes There are several other canned themes you can use rather than the default theme. There are 12 additional themes that you can use without installing any other packages: “cerulean”, “cosmo”, “flatly”, “journal”, “lumen”, “paper”, “readable”, “sandstone”, “simplex”, “spacelab”, “united”, and “yeti”.

It feels like this spring has been especially terrible weather-wise. We have gotten a lot of snow and it has been cold. To evaluate whether this is the case or whether I have hindsight bias, I pulled some historical weather data for the month of April from Weather Underground. library(dplyr) library(forcats) library(ggplot2) library(ggridges) library(readr) library(viridis) # Read in data april = read_csv("~/Documents/github/Public-Stuff/data/april-weather.csv") # Filter dates april = april %>% filter(date <= 11) I grabbed data back to 2008 (avialable at https://raw.

This post is the fourth (and last) in a series of blogposts in which I respond to questions from the students in the Becoming a Teacher of Statistics course. In today’s posting I respond to questions that asked me for predictions about the future of statistics teaching and statistics education research. Before I get into the Q&A, let me just state: Prediction is hard. Leland Wilkinson in The Future of Statistical Computing reminded us of this when he cited a prediction about computers that Andrew Hamilton made in a 1949 issue of Popular Mechanics

Projects

e-ATLAS Project

Evaluation and Assessment of Teaching and Learning About Statistics (e-ATLAS) was an NSF-funded project from 2011–2013 that developed high-quality instruments to help evaluate the effectiveness of past and on-going efforts to reform the teaching and learning of introductory statistics at the tertiary level (DUE-1044812 & 1043141).

AIMS Project

Adapting and Implementing Innovative Material in Statistics (AIMS) was an NSF-funded project from 2006–2010 that developed lesson plans and activities based on innovative materials that have been produced for introductory statistics courses (DUE-0535912).

BioSQuaRE

BioSQuaRE is an instrument, created via an HHMI grant, to assess the quantitative readiness of students planning on majoring in biology or the life sciences.

CATALST Project

Change Agents for Teaching and Learning Statistics (CATALST) was an NSF-funded project from 2008–2012 that developed materials for teaching a radically different introductory statistics course based on randomization and bootstrap methods to provide students a deep understanding of statistical inference (DUE-0814433).
