Consider the following set of sample data.

Answer 1

Consider the following set of sample data.

21 29 32 38 38 45 50 64 72 100

For the given data, the mean is 48.9, the median is 41.5, and the mode is 38.

Suppose the observation 21 in the data is mistakenly recorded as 2 instead of 21. For the sample with this error, the mean is 47, the median is 41.5, and the mode is 38.

Suppose the value 21 in the original sample is inadvertently removed from the sample. For the sample with this value removed, the mean is 52, the median is 45, and the mode is 38.
