This video will show how to find standard deviation and variance for one variable statistics in Casio 300ES Plus Scientific Calculator. This process is similar for those who own a Casio 115ES Plus Scientific Calculator
Thank you for this! I'm in a stats class where it requires me to write long and complicated formulas and I simply wouldn't have the time in an exam to calculate the mean and SD of some of the questions (which is essentially just step 0 in some questions). This will save me a bunch of time with a lower chance for error!
Here is the video I have that shows you how to add numbers into your calculator. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nqcW50m1Xy8.html Good luck!
No, the population SD is calculated differently than the sample SD which is why the numbers are different in your calculator. The variance is found based on those numbers, so those answers will be different as well.
Here's the first video to get you started! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-nqcW50m1Xy8.html After that check to make sure you don't have any commas, decimals (at the end of numbers), or math symbols (+, -) in your lists. If you continue to get an error you can reset your calculator to clear everything out. Shift, 9(CLR), 3:All. This will clear everything if you still have issues with your lists. Good luck!
