10 questions from this quiz
To simplify calculations with data
y=x−aby = \frac{x - a}{b}y=bx−a
Shifts the data
Scales the data
xˉ=byˉ+a\bar{x} = b\bar{y} + axˉ=byˉ+a
Var(x)=b2×Var(y)\text{Var}(x) = b^2 \times \text{Var}(y)Var(x)=b2×Var(y)
SD(x)=b×SD(y)\text{SD}(x) = b \times \text{SD}(y)SD(x)=b×SD(y)
