Summary
-
-
+C always even when working backwards, it is not assumed
-
a Valid pdf (probability density function) must have all probabilities between 0 and 1 inclusive and should add up to 1
-
check the type of graph displacement, velocity, acceleration
-
as n increases in the sample the std deviation decreases (the graph gets narrower as n increases) but also the graph of a sample is narrower than the original graph the true distribution
-
underestimate on an increasing AND decreasing function occurs on either the right OR left and in the middle check both sides to see if which is lower. (or if minimum) Overestimate on this kind is maximum if in the middle otherwise check sides.
- f''(x) roots
- f'(x) stationary points
- f(x) inflection points
- f''(x) stationary points
- f'(x) inflection points
- f(x)
- f''(x)
- f'(x) roots
- f(x) stationary points
when it is added or timsed, it is added JUST to the original (not the plus K), and it is timsed or divided to the original AND to the K.
-
for discrete values the calculator uses equal and greater than not just pure greater than so often has to be changed
however for continuous values it does include it do nothing needs to be changed (the opposite is not true?)
the central limit theorem: that a sample of means (averages) of large enough size will be able to be modelled with a normal function regardless of if the original probability function was normally distributed or was positively or negatively skewed. As n increases the function will become more normal (bell-shaped)
std dev over root n, as n increases the range decreases
