hi there,
the book on github openintro-statistic-slides and the book which i download
OpenIntro Statistics
Fourth Edition
is different?
what is the issue?
chapter names are same, but the content in the chapter is different.
many thanks,

Dear @mine-cetinkaya-rundel,
On slide 13 of Ch. 6, it says if the success-failure condition cannot be fulfilled, use randomization instead. What does randomization mean here exactly? I couldn't seem to find the explanations in the textbook.
Hope to hear from you soon, and I apologize if this is not the preferred method of reporting a question.
Suggestion from Rivo Randrianarivony via email:
By the way, I understand that the goal is not to overwhelm the student with mathematical notations but then sometimes it's better to make things more precise. For example, on slide 55 of chap. 3., it would be better to add a subscript to the
$S$ and$C$ r.v.'s in the variance formula like so:$V(S_1 + ... + S_5 + C_1 + ...)$ so that we can talk about the time spent on the first stat homework for$S_1$ , etc..
Some of the R code in the examples doesn't follow best practices
setwd()
commands sprinkled around -- replace with use of here::here()
(a) Are these data collected as part of an
experiment or an observational study?
(b) What is the most common dog name?
What is the most common cat name?
(c) What names are more common for
cats than dogs?
(d) Is the relationship between the two
variables positive or negative? What
does this mean in context of the data?
thank you,
rao
Use of literate programming via Sweave will likely not be very helpful at this point, but the slides could benefit from a xaringan / Rmd conversion. This would allow us to test and maintain the code easily and provide a good starting point for faculty who are R users.
One issue is that we might not want to remove the PDF option completely, and we don't want to maintain two code bases, so this would require a solution where slides can be written to PDF and HTML easily from the same source files.
This needs to happen before a release can be issued.
Create a makefile to compile all chapter slides at once. This will help easily check that any changes made to the style file do not break anything.
From Adam Alsamadisi over email:
We’ve corresponded once before, but I believe there’s an error in the slides for 3.4 on Random Variables. Slide #13 has the incorrect formula for the standard deviation of linear combinations of random variables—I thought it may be up for interpretation, but I noticed another slide deck attributed to you (found here: https://docs.google.com/presentation/d/16DKhcwkkA3bulJ7jaECAEASVVM30_Yf_CBD1ACNZYD4/edit#slide=id.g1729f44319_0_0) had the correct calculation.
