- i = N/n
- nth element
- Population (N) = 20Sample Size (n) = 10
- i = 20/10 = 2 i = 2 so, 2 is our nth element
- Since only 10 students will represent the class, the teacher explains how she will choose 10 students among all the 20 students. Using the Interval (i) formula.
- Upon explaining the interval formula, the teacher also mentioned the nth element, which will determine the 10 students that will represent the class.
- In order for the class to understand fully what the teacher is saying, the teacher shows how to solve the nth element with the help of the interval formula. i represent the interval and capital N is for the population, the small n is for the sample size.
- In accordance with the nth element, the teacher proceeds to choose every 2nd in the population list will represent the class for the dance competition.
- Upon selecting the 10 students, these students proceed to another room to start practicing, while the 10 remaining students remain in their classroom to wait for their class.
- The day after their teacher selects the ten class representatives, Chad and Shaun talk about what their teacher has taught them, which is Systematic Random Sampling learning how to solve using the Interval formula and getting the nth element. Overall, they both had a wonderful day.
