#### Answer

Mean: 26.17 Median: 30.5 Mode: 33 Median is the best descriptor

#### Work Step by Step

To find the mean, we add up all of the values and divide by the total number of values. Mean: $\frac{1+29+33+31+30+33}{6} = 26.17$ To find the median, we order up all of the values from least to greatest and find the middle number. If there are an even total number of terms, then we take the average of the two terms that are closest to the middle. Median: $1, 29, 30, 31, 33, 33 \rightarrow \frac{30+31}{2} = 30.5$ To find the mode, we determine the number that shows up the most. Mode: $33$ There is an outlier in the data so the median will be the best measure to describe the data.
