Step-by-step explanation:

Arrange the data in ascending order:

1.  1 1 2 3 4 7 9

Median = middle number = 3.

Q1 = 1

Q3 = 7.

2.  26 31 34 38 42 66 74 78

Median = mean of 2 middle numbers = 40.

Q1 = 31.

Q3 = 74.

3.  36 45 49 52 53 64 81 87 93

Median =  middle number = 53.

Q1 = 47.

Q3 = 84.
