Interdisciplinary Blog- Mr. Rich's Statistics Class

In Mr. Rich's class we are doing a lesson called Standard Deviation. Standard Deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. I'm usually good at statistics ,but this specific lesson was a little confusing to me due to all the steps you have to do to find the answer. With time I've realized that if you know the steps then the problem will be much more easier and quicker to solve. In my opinion, the skill that has to be used with this lesson is memorization because if you memorize the steps then you basically have all you need. As well using a calculator, to find the standard deviation there are further steps you need to know which are very little to find the answer on the calculator. This is much easier than writing out the table and doing all of the seven steps. In the calculator, you first have to click on "Stat" then go all the way down to number four and clear the list after doing that you go "Stat" again click on number one and start writing down the numbers. after that you go to "calc" click on number one and it shows all of the long seven steps you did by hand. I love math, and I think i always will, but this lesson taught me that my memorization skills are not so great. But I'm happy that with the new technology we have today calculators are a great resource.
