Answer:
2
Step-by-step explanation:
To find the median of a group of numbers, arrange the data points from smallest to largest. If the number of data points is odd, the median is the middle data point in the list. If the number of data points is even, the median is the average of the two middle data points in the list.
9 people took 1 portion, ( so we write 9 1s)
8 people took 2 portions, (so we write 8 2s)
7people took 3 portions, (so we write 7 3s)
7people took 4 portions and (so we write 7 4s)
2 people took 5 portions. (so we write 2 5s)
1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 4 4 4 4 4 4 4 5 5
Now that you have written out all of your data points, just find the number in the middle which in this case is: 2
The answer is:
The median number of portions of vegetables that people surveyed yesterday was 2 portions.
