Dr. Greyeagle calculated descriptive statistics for the age of residents in a nursing home. She reported the mean age as 75 years, with a standard deviation of 10 years. Later she found that she had made an error in her calculations. One resident's age was entered as 27 when it should have been 72. What will happen to the standard deviation when this correction is made?

◦ It will decrease.
◦ It will increase.
◦ It will not change.
◦ It will increase, but only if the mean remains the same.
