Arrange the data in an ascending order. 2,2,2,2,7,7,7,7,7 Here, number of observations = 8 (Even) Therefore, Median =
4th observation + 5th observation
2
=
2+7
2
=

2
=4.5
Mean=
2+2+2+2+7+7+7+7
8
=

8
=4.5 Hence, statement 1 is correct Mode is the value that occurs most often. In the given data, both 2 and 7 occur four times. So, the mode isboth 2 and 7. Hence, statement 2 is correct.
