I think so, because we can find the mean, median, mode and range for the dataset. The mean is \$29/5=\$5.8; the median is \$6 because it's the central value of all the values when ordered: \$4, \$5, \$6, \$7, \$7; the mode is \$7 because \$7 is repeated; and the range is \$3 ranging from 4\$ to \$7, or could be defined as the interval \$4-\$7. From these other stats can be derived.

I misunderstood what you were asking. Also apologies for silly errors and omissions. From your comment I see that you were expecting me to select one of the list, not make a statement about the list which summarises the data. If thatâ€™s so, then I would go for the median of \$6 because the mean (\$5.80) and the median (\$6) are close, and the mode is biased towards the highest cost of lunch. Also, all the figures are whole dollars, so the median is naturally a whole number of dollars and better represents the whole data. What took you so long to comment on a 5-year old question?
