Question

CAN SOMEONE HELP?????????
The salaries of 830 lawyers were recorded and analyzed. The analyst later found that the lowest salary was incorrectly recorded 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?

Mean
Minimum
Mode
Median

Answer 1

The median (half-above and half-below) could not have changed, because "corrected value was still lower than any other salary" does not change the position of that observation (still least) in the sorted list of salaries.

Answer 2

Answer:

Median                      

Step-by-step explanation:

Since, after correction also salary is the lowest salary than any other salary, this means outlier is present in data and it affects the data so much. Thus we use the Median here.

Mean, Median and Mode are used to measure Central tendency.

Mean is the average of all observation. It is mainly used the data is normally distributed and it has no outlier.

Minimum: It can be found by arranging the data in ascending order, the first value we will get is the minimum value.

The middle observation of given data is called Median. It is used when an outlier is present in the data.

The mode is the observation which has a high number of repetitions (frequency).
