12. Writing Assignment – Pop Quiz Sigma – standard deviation - population
Parameter
mu – a mean – an average - population
Parameter
x-bar – a mean – an average - sample
statistic
s – standard deviation - sample
statistic
The number of “standard deviations” the score is from the mean
population
Sigma squared and s squared - variance
Sigma is parameter (population) s is statistic (sample)
Deviation scores
(x-µ) for population (parameter) (x-x) is statistic (sample)
Sum of squares
On left is statistic on right is parameter
Standard deviation
s is statistic sigma is parameter
Degrees of freedom
sample

Each of these are deviation scores
3 – 5 = -2
-22= 4
6 – 5 = +1 -2 1 3 -1 4 1 9
12= 1 3 -3 -1 1 9 1
Σ(x - µ) = 0 50 36 36 2
= 2
10 - 1
This is the standard deviation! 5 4
