Randomly pick 25 fish from the entire pond and weigh each of them
Explanation:
Centimeters, feet and inches measure length, not weight.
To find the average weight of fish living in a large pond, the scientist will randomly pick 25 fish from all over the pond. Next, each fish will be weighed. The weight of all 25 fish will be added and the total will be divided by 25. This will give you the average weight of a fish living in the large pond.
