This course was taught between 2018 and 2025. It is replaced by a new course 'sampling and estimation' in 2026-2027, but I am leaving the materials here for archival reasons.
This course aims to give students a firm introduction in three broad, and related topics: (1) inference - how do we use small sets of data to produce knowledge about the world around us; (2) survey data analysis, in particular sampling and analyzing complex datasets; (3) survey design - why are surveys designed the way they are? The focus here is on the overall design of a study, not on the design of individual survey questions.
Dear all,
Nine years ago I started blogging. I have been quiet the last few years when it comes to blogging. Perhaps I will pick this up again, perhaps not. What changed quite a bit is how I work as a scientist. I am using R now as my default software for analysis, and have also started to use GitHub for version control, as the cool kids nowadays do. Anyways, my website was long due an overhaul.
There are several ways to do an exit poll, but they all come down to asking people what they voted, right after they went into the voting booth. The first succesfull modern exit poll was conducted in 1967 to predict the governor’s election of Kentucky .
One of the difficulties in exit polling, is that some people might not want to say whom they vote for, especially if this person is politically controversial.
