To construct confidence interval for the mean, we often use quantiles of standardized sample mean distribution. Here, I include a list of cases where I’d use quantiles of t-distribution versus quantiles of normal distribution for that purpose.

Note: the below text could be directly translated to answer when to use t-test versus z-test in testing hypothesis about the mean parameter.


I spent the last days of 2018-19 winter break in Austin, TX where I traveled for RStudio 2019 conference. I attended e-poster session and two days of the conference: Jan 17-18. Below I list some of the topics from the talks that I particularly liked and I think I am likely to benefit from in the future. Also: The official repo with abstracts for every session, workshop (together with workshop files free to download for most if not all of them), and e-poster can be accessed here.


W 2015 roku zdobylam tytul Magister na kierunku Matematyka na Politechnice Wroclawskiej. W sierpniu 2016 rozpoczelam aplikacje na programy doktoranckie na kierunku Biostatystyka w Stanach Zjednoczonych rozpoczynajace sie jesienia 2017. Dostalam i zaakeptowalam oferte z Departamentu Biostatystyki na Johns Hopkins Bloomberg School of Public Health w Baltimore (stan Maryland), oferujacego jeden z 3 najlepszych (ex aequo) programow na kierunku Biostatystyka w USA wg rankingu z 2018 roku. W notatce opisuje etapy rekrutacji i podaje swoje obserwacje i wskazowki.
