Question

you counted 4 quadrats with the following number of plants: 5, 7, 6, and 8. first step: find the average number of plants per quadrat.

Explanation:

Step1: Calculate the sum of plants

$$5 + 7+6 + 8=26$$

Step2: Calculate the average

The number of quadrats \(n = 4\). The formula for the average \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). Substitute \(\sum_{i=1}^{n}x_{i}=26\) and \(n = 4\) into the formula:
$$\bar{x}=\frac{26}{4}=6.5$$

Answer:

The average number of plants per quadrat is \(6.5\)
