It will do that if you are finding the 1-var stats of a probability distribution. Normally it shows up. It's hard to say without looking at the data set.
You can try clearing you memory by hitting 2nd +7 1 2. It won't show up if it's a probability distribution. You can also try going to 2nd STAT arrow over to math and select the one that says standard deviation. I can't remember the number off the top of my head.
@@mageic7001 you use it if you are finding a weighted mean or if you put the frequency of values in another column. Leave it blank if you aren't using a frequency list.
I have the teaching software from TI. I know they have student software available for purchase. There's also a free online graphing calculator called ClassCalc that does most of the things the TI-84 does
New favorite math youtuber. I was about to cry.
I'm sorry you were about to cry.
thank you. you saved me from throwing my phone across the room 😂😂
Thank you so much I wasted an entire day trying to figure it out... super helpful..took me minutes after your video
THANK YOU STRAIGHT TO THE POINT LOVE IT
Thank you so much, you have no idea how much this helped, my professor tells us to ask again next semester when we ask him a question
I'm sorry to hear you are in a situation like that. It's frustrating!
Richard Quiles get him fired and report him to the dean
You saved the day! I wish every math professor I had taught like this!
Great video, this gal is super sharp. Thanks so much for the help.
Glad it helped you
Thank you so much for this! I had almost given up on my graphing calculator!
I'm glad the video helped. Graphing calculators are amazing tools, but can be frustrating!
Queen you saved me
thank you for this every other video is made in such an unprepared format.
Thank you!very detailed and nice pace, much appreciated! This is a way easier way to find the Variance!
It is definitely easier in the calculator! I'm glad you found it helpful.
Thanks for this. I was doing this by hand because I don't know how to use stat crunch yet.
you saved my grade thx
You're welcome
God bless you woman
Thank you I did not want to do Sx by hand!
It's definitely not practical to do it by hand.
THANK YOU!!!!
You're welcome. Glad it helped.
Hi how do you enter negative values into that because when I try to calculate with negative numbers it says error?
Make sure you use the negative button (-) left of enter, and don't use the subtraction button. The calculator sees them differently.
@@MathandStatsHelp I use the negative button and it still says error for some reason :(
@@MathandStatsHelp thank you soo much!!!
I had the same exact question/ problem with it
You are great. Thank you
QUEEEEEEEEEEEEEEEEEEN YOU SAVED MEEEEEEEEEEEE THANK YOUUUUUUUUUUUU :)
I'm glad I was able to help!
you are the best.
Genius.
Thank you so much! I learned so much from watching your video.
Why is the Sx blank on my ti-84?
everything else shows up fine
It will do that if you are finding the 1-var stats of a probability distribution. Normally it shows up. It's hard to say without looking at the data set.
@@MathandStatsHelp What does the frequency list on 1-var stats mean?
You can try clearing you memory by hitting 2nd +7 1 2. It won't show up if it's a probability distribution. You can also try going to 2nd STAT arrow over to math and select the one that says standard deviation. I can't remember the number off the top of my head.
@@mageic7001 you use it if you are finding a weighted mean or if you put the frequency of values in another column. Leave it blank if you aren't using a frequency list.
what app is that that simulates the calculator?

Can you use this ev at a card game transparent
what if the question doesnt have any data set but asks for variance and deviation for samples of the following (n=8, Ex^2=87,Ex=26)
How do you do when you have ex 200 observation...
