Answer:
first and last
Step-by-step explanation:
Total observations:
3 + 7 + 7 + 4 + 1 = 22
There are 22 observations, so data from 22 households
Median position: (n + 1)/2
(22 + 1)/2 = 23/2 = 11.5th value
median is the average of 11th and 12th values, both are 2. So the average is also 2
Therefore, Centre is at 2
