I'm gonna be a high school senior also. I've taken most of the standard high school classes for AP/TAG/GT/whatever you wanna call it. Math and history are my forte, but - excuse the lack of humility - I'm pretty good in most subjects, so feel free to ask for help!

 

Also fluent in Chinese and took that AP test.

 

Of course, if you guys just need someone to cry about the stress of student life, I'm hurrrr for that too :P

I can help people whenever during 2nd semester aka Feb-June. 
These are the subjects I can help with: Chemistry, Biology (Bozeman Science will probably be more helpful than me tbh), environmental science, all levels of math up to calculus, English, neuro, apush, micro/macroeconomics (not an expert), and maybe Spanish too (not a native speaker) lel.

Honestly though, Google is your best friend  :imstupid: 
If I need help with Spanish Lit. at like 2am, I'll come here I guess  :ohbi:

please find the mean, median, and mode of this data set: 30, 37, 32, 39, 33, 34, 32

don't judge me :._.:

 

also how do u find mean again? my teacher went through the notes to fast for me to finish writing.

to find the mean -> just find the average of the set of data aka add all the numbers and divide by the # of values (7)

median -> order the numbers from least to greatest (30, 32, 32, 33, 34, 37, 39) and the value in the middle is is the median. if there are two numbers in the middle, then you find the avg. of those numbers, but with your case only one number is in the middle.

mode -> the value that appears the most often in the data set

to find the mean

 

add everything together and divide by how many there are

30+ 37+ 32+ 39+ 33+ 34+ 32 =237

237/7 =33.9

what is this

i meant that i did them without taking 1000000 years

was too lazy to do all of them hehe, does it make sense though?
