Testimonials

I want to thank you very much for your random number generator! We teachers are supposed to check for understanding with all of our students. I am sure you are aware of all the stumbling blocks to actually calling on students randomly. I hope that your random number generator, with its ability to generate integers within the range that I specify, will help me to better sample my students for their understanding. More important to the students is the classroom jobs like setting up the technology each day, passing out folders, etc. (I teach 6th Grade in the USA.)

The most important feature of your generator is the ability to set the range/limits!

I tried popsicle sticks in a can but found that method to be ‘uncannily’ unfair! It seemed like I kept getting the same sticks!

I tried writing numbers on index cards, but I can't shuffle cards to save my life! (Besides, when I pick the cards without looking, you know there is bias in that as well … somewhere in my brain.)

I finally purchased some dice from the net that have various numbers of sides. But that didn't work either because the number of students in my class changes throughout the year as the students in our area have a somewhat high transiency rate.

I was at a loss, and the students have been getting upset with me.

In the past I have Googled for something like this, but I guess I never quite put in the correct words to arrive at your site, but I THANK GOD THAT I FOUND YOUR SITE TODAY! And, yes, you may use this testimonial!

Dr. Haahr,

I used a list of your new random numbers in your new set generator for the dog races on Friday March 14, 2008. Using your sets on the last 4 of 13 races generated 2 trifectas. The sets I use are chosen by calculating over and over until the sets generated line up with the previous winning numbers. In this particular case I used races 1 through 9 and matched them with the sets generated. Of course there is not a 100% match for all numbers. However, the way the races are set up, the 1st three finishing positions are the ones to key on.
