standardised score

[tawdry yarrow]

mean for test 1 is

at the middle

cuz the centre of the bell curve is roughly the mean / median

then +3 standard deviation away from the mean

is 99.8% of data

pretty much all data

so you take the end of the curve and take that away from the mean

to get 3 standart deviation

and divide by 3 to get 1 standard deviation

I’m confused what this means

[tawdry yarrow]

uh

so mean +/- 3 standard deviation is 99.8% of the data

[spring sierra]

Oh okay,is this true for any questions or just this one. I just have never heard of this 😭

[tawdry yarrow]

its true for all bell curves

[spring sierra]

I got a 3 on the February mock 😭 on higher paper so probably not since it’s very time consuming when I try teach myself

[tawdry yarrow]
