I think so, because we can find the mean, median, mode and range for the dataset. The mean is $29/5=$14.5; the median is $6 because it's the central value of all the values when ordered: $4, $5, $6, $7, $7; the mode is 2 because $7 is repeated; and the range is $3 ranging from 4$ to $7. From these other stats can be derived.
