The salaries of 750 teachers were recorded and analyzed. The analyst later found that the lowest salary was recorded incorrectly as $0. After the error was corrected, the report showed that the corrected value was still lower than any other salary. Which sample statistic must have remained the same after the correction was made?
A Mean
B Median
C Mode
D Minimum

Step-by-step explanation: Because "adjusted value was still lower than any other pay" did not change the position of that observation (still lower) in the sorted list of salaries, the median (half-above and half-below) could not have changed.

What is a median?

When a given data set is arranged in ascending order the observation which at the between of the data is the median of that data set. It is a value in the set whose left and right both have the same number of observations. For example: In the given data set 0,2,4,6,8,10,12; 6 is the median for the data set since it has the same number of values on its left and on its right.

For any given data set if the value of the minimum is changed, the median of the data set will still remain the same, until and unless the data set has only two observations. Therefore, The sample statistic must have remained the same after the correction was made in the median.

Hence, the correct option is B.
