You will be matching each graph with the standard deviation measure that best fits it.
Which standard deviation value best matches Graph A?
SD #1 $\sigma=0$
SD #2 $\sigma=1.02$
SD #3 $\sigma=10.2$
SD #4 $\sigma=100.2$
You will be matching each graph with the standard deviation measure that best fits it.
Which standard deviation value best matches Graph C?
SD #1 $\sigma=0$
SD #2 $\sigma=1.02$
SD #3 $\sigma=10.2$
SD #4 $\sigma=100.2$
