My Year in Books: Technical Edition

ByAnnMaria De Mars December 31, 2014January 3, 2015

I read a lot. This year, I finished 308 books  on my Kindle app, another dozen on iBooks, a half-dozen on ebrary and 15 or 20 around the house. I don’t read books on paper very often any more. It’s not too practical for me. I go through them at the rate of about a book…

My Success Is Personal

Below are the results of our pretest on knowledge of fraction operations of 322 students in grades 3 through 7, attending schools on and adjacent to American Indian reservations.

How not to get your ass fired: Part 1

ByAnnMaria De Mars December 3, 2014December 3, 2014

I was going to call this new category for my blog “Mama AnnMaria’s advice on not getting your ass fired”  but it turned out to be too long to fit in the box. It may surprise young people in the work place to find out that people who admit to having screwed up are often…

ByAnnMaria De Mars December 2, 2014

What if you wanted to turn your PROC MIXED into a repeated measures ANOVA using PROC GLM. Why would you want to do this? Well, I don’t know why you would want to do it but I wanted to do it because I wanted to demonstrate for my class that both give you the same…
