Each of the dot plots shown represents the number of glue sticks brought in by each student for two classes, class A and class B. Consider Class A. If the student who brought 1 glue stick instead brought 7 glue sticks, how would the standard deviation of the number of glue sticks for Class A change?
The standard deviation would decrease.
The standard deviation would increase.
The standard deviation would remain the same.
It is impossible to determine without calculating the exact values.
