Statistics for User Experience Researchers

Statistics for User Experience Researchers. Sunday, September 6, 2009. Z is for Z Test. Today we discuss the Wonderful World of Z Tests. I started hearing from co-workers last year, about testing means with Z-tests, and I wondered why one would use a Z-test when one has perfectly good t-tests. Z-tests can also be used to test proportions, such as people who prefer Coke vs. Pepsi. Why not use a Chi-square. Out of the 1,000 Funhouse players, 750 choose to play as JP Patches. In user experience, we would ha...

Statistics for User Experience Researchers: Comparing two variables

http://www.uerstats.blogspot.com/2009/07/comparing-two-variables.html

Statistics for User Experience Researchers. Thursday, July 30, 2009. Sometimes we want to know how the scores in Variable 1 compare to Variable 2. A common situation is comparing your study participants' pre-test and post-test scores. Or you might compare your participants' level of satisfaction with two things such as photos manipulated in Pretty Photo Premier versus Super Snapshot Suite. For these situations, we would use Mr. T-Test again, this time a paired samples t-test. 99) = 4.85, p. T-test, infer...

Scarlet Hamster: January 2009

Friday, January 23, 2009. Revolution via Facebook in Egypt. In response to the military action in Gaza, several Egyptians have been using Facebook for their social activism. Sunday, January 18, 2009. I feel exhilarated from today's cooking efforts. I had a strong urge to cook, so I made:. S Chinese-style egg flower soup. This recipe is an old favorite of mine.

Scarlet Hamster: January 2011

http://scarlethamster.blogspot.com/2011_01_01_archive.html

Friday, January 07, 2011. Using Skype for long-distance romance. Really great article in today's paper about college students sustaining romantic relationships with video chat and technology. The implication is that the Turkey Drop (dumping boyfriend during Thanksgiving break at home) is no more with all this connectivity to keep the love alive while apart. That may be true, but I also suspect that the technology keeps some relationships on life support much longer than they should.

Monday, July 27, 2009. I've made great progress on my baby coat dress. The alpaca is a beautiful pruney color. It's sheddy as alpaca is wont to be, but I think the softness and color make up for that. I need to sew on the arms and buttons and then wash and block the thing. PS I decided to move all my blogs over to free blogspot hosting. So I have layers of broken links everywhere. bear with me please.

Scarlet Hamster: February 2009

http://scarlethamster.blogspot.com/2009_02_01_archive.html

Wednesday, February 18, 2009. Yummy cold Korean soup noodles. Side dishes of kimchi, pickled ginger, and fried mushrooms. My first from-scratch attempt at this dish. Sunday, February 08, 2009. I finished the Ripple Scarf a while ago. It is lovely and soft and just a tiny bit sheddy because of the alpaca. I am tempted to make another lacy scarf or smoke ring soon with qiviut (muskox down). But I am not sure I need to fork over $90 for a skein at this moment. Subscribe to: Posts (Atom).

I am tempted to make another lacy scarf or smoke ring soon with qiviut (muskox down). But I am not sure I need to fork over $90 for a skein at this moment. Here's what the sweater looks like flat.

Scarlet Hamster: More goofing around

Monday, July 27, 2009. As a good recessionista, I have decided to give up official web hosting and domain names. Blogspot serves my purposes, and it sure is easier to use the canned templates than for me to dredge up some HTML from the dark corners of my memory. Hence this new domain name.

Scarlet Hamster: Peanut butter jar camping lamp

http://scarlethamster.blogspot.com/2009/08/peanut-butter-jar-camping-lamp.html

Sunday, August 02, 2009. Peanut butter jar camping lamp. I made this lamp based on instructions from Made by Cynthia Rae. I had all the materials and tools hanging around aside from the battery-operated candle light. Since peanut butter jars are rather difficult to come by, I've been experimenting with other containers. Plastic is key because broken glass is no fun. I got a square salsa jar that might work. hmm. Subscribe to: Post Comments (Atom). View my complete profile. Stats for UX Researchers.

STOP UERSS | No a la Unión Europea de Repúblicas Socialistas Soviéticas

No a la Unión Europea de Repúblicas Socialistas Soviéticas. Julio 13, 2012. Si realmente este proyecto de la UE es una unión que debe beneficiar a todos, por qué países como España, Portugal o Italia solamente pueden financiarse a unos intereses abusivos, mientras que el resto de los países que lideran esta UE lo hacen a un tipo de interés prácticamente nulo e incluso negativo? No debemos exigir los beneficios verdaderos de esta unión y no solo aquellos que nos pintan como supuestos beneficios? Http:/ ww...
