Recently my good friend Joey Shavelle of Jolo Studios put some additional functionality into two of our statistical simulators. For the sample mean simulator he added code that calculates the mean of the means and the standard deviation of the means. Here’s what it looks like when I had a population mean of 127, a standard deviation of 32, and a sample size of 50 with 1000 simulations:

He also added the same code to the sample proportion simulator that calculated the mean sample proportion and the standard deviation of the sample proportions. Here’s a shot of what it looked like when the population p was 0.3, a sample of size 100 was used, with 1000 simulations:
So, check them out and use this new functionality in our lessons that require it if you haven’t already finished statistics at this point.
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.
