Consider the following set of sample data.

21 29 32 38 38 45 50 64 72 100

For the given data, the mean is , the median is , and the mode is .

Suppose the observation 21 in the data is mistakenly recorded as 2 instead of 21. For the sample with this error, the mean is , the median is , and the mode is . The mean , the median and the mode

Suppose the value 21 in the original sample is inadvertently removed from the sample. For the sample with this value removed, the mean is , the median is , and the mode is . The mean , the median , and the mode
