O.k. So, I’ve updated the statistics programs for the TI-83/84 that are needed to do the simulations for Unit #13 (Statistics) in the new Common Core Algebra II.
Here are the programs and a description of what they do. Click on the link to download one and then use TI-Connect (and a cable) to get them onto your calculator. If you are unsure how to do this, click on the link below:
Instructions for TI-Connect (Don’t download statistics programs from this link).
Here are the programs:
NORMSAMP is a very simple program. The user specifies a mean and standard deviation for an infinite population that is normally distributed. The program will then simulate a sample from this population of any size and perform multiple simulations. This output is a list of sample means and a list of sample standard deviations.
PSIMUL will pull a sample (of any size) from a population with a given proportion specified by the user. The population is assumed infinite (sampling with replacement essentially). The program will create as many samples as the user specifies and then exports a list of sample proportions.
This program allows the user to put in two lists with experimental results (Treatments 1 and 2). It then scrambles the data randomly and recalculates the differences in the treatment means. The user can do this as many times as they want in order to establish if the original difference was statistically significant.
Lesson planning, grading, and organizing materials can take up hours of precious time. Having ready-to-use resources means less stress and more space to focus on students. With the right tools, teachers can spend their energy on what matters most: inspiring a love of math and helping every learner succeed.
