Question
A scientist wants to find the average weight of fish living in a large pond. So she will use the weights of 25 fish from the pond to find the average weight. Answer the questions below. \( \begin{array}{l}\text { (a) Which unit(s) could be used for the unit of measurement? Check all that apply. } \\ \square \text { seconds } \square \text { ounces } \square \text { hours } \square \text { pounds } \square \text { minutes } \\ \text { (b) Which of the procedures below would be the best way to find the average weight? } \\ \text { Randomly pick } 25 \text { fish from the entire pond and estimate their weights. } \\ \text { Randomly pick } 25 \text { fish from the entire pond and weigh each of them. } \\ \text { Pick } 25 \text { fish from a shallow region of the pond and weigh each of them. } \\ \text { Pick } 25 \text { fish from a shallow region of the pond and estimate their weights. }\end{array} \)

Answer
**(a) Units of measurement**
- ounces
- pounds
**(b) Best procedure to find the average weight**
- Randomly pick 25 fish from the entire pond and weigh each of them.
Solution
**(a) Units of measurement**
The weight of a fish is measured using units of mass or weight. Among the given options, the appropriate units are:
- \( \text{ounces} \)
- \( \text{pounds} \)
Units such as seconds, hours, and minutes measure time and are not suitable for weight.
---
**(b) Best procedure to find the average weight**
The goal is to compute the average weight of the fish. The best procedure would involve both randomly selecting the fish (to avoid bias) and accurately measuring their weight rather than estimating.
Thus, the correct procedure is:
- **Randomly pick 25 fish from the entire pond and weigh each of them.**

Simplify this solution Beyond the Answer
For measuring the weight of fish, you could use "ounces" and "pounds" as relevant units of measurement. Both are commonly used to quantify the weight of fish and are much more applicable than units like seconds or hours, which are related to time, not weight! When it comes to the best method for finding the average weight, the most accurate procedure is to randomly pick 25 fish from the entire pond and weigh each of them. This method ensures that your sample is representative of the entire pond's fish population, avoiding any biases that might occur if you selected fish only from one area. Happy measuring!
