This chapter was a breeze for me, thanks to this lecture.  -Sherley J. Forestal

What did this video teach me? Everything! I appreciate you teaching me how to compute statistical data using my scientific calculator. It really does save a ton of time. Tosha R. MFG1106

Hello Ms. Hearn, Im also in your MFG 1106 class. My name is Puja P.
One take-away from this video is if I don't have the calculator on hand, im still able to find standard deviation.

Professor, I learned how to calculate these problems in my calculator. Thank you for making this so easy.

Hello Professor,

Pinder Perez MGF1106 one thing I liked about this video is how you explain the steps for calculating standard deviation on the TI30XIIS.

Hello Prof Hearn. My name is Luisana Mangan, and I am currently taking MGF1106. Something I learned about this video is how to calculate the standard deviation in an exercise. Also, how to use the calculator to find out the standard deviation, which makes it much easier.

One part that I loved learning about this video is how we can calculate and obtain the same result with a calculator, instead of going through the long process which can be stressful but with your explanation you did everything much easier. Thank you so much!

"To enter the data, first you have to clear the calculator by hitting 2nd then the STATVAR. The second step is to hit data( when entering the data hit the arrow button two times to keep the FRQ ; it is always one). Once all the data is entered press STATVAR to calculate the standard deviation."

One thing I like about this video is the way that Ms. Hearn explains mean calculation and her added pictures of examples

The sample standard deviation is denoted by "s" and the population standard deviation is denoted by the Greek letter sigma.

This section kept throwing me through a loop for some reason. One thing this video is really great for is helping me understand the step by step instructions for both "by hand " and calculator for Standard deviation.

"The standard deviation of the data the sample standard deviation of the data SX and what do you see there."

I like how in this video Ms Hearn also explains how to do it by hand, i particularly prefer to do my calculations by hand as a way to make sure my calculations are right and this video made it so easy for me to understand how to calculate standard deviations by hand, step by step.
