Answer:
Mean =
sum of all observations/ Total number of observations
21/7 = 3
Median =
No. of observations = 7
Since the number of observations are odd, the median can be calculated as,
[(n + 1) / 2]th observation
[(7 + 1) / 2]th observation
4th observation
= 2
Mode =
Most frequently coming number is 1.
Hence, mode = 1
