QuestionSimon plans to make gloves.
One morning, Simon decided to carry out a survey to find the mean hand span of people in Wales.
He decided to sample systematically.
He decided to sample from the first 240 people who pass him in the street during the morning.
He wanted to take 20 people's hand span measurements. Explain how Simon could use systematic sampling to obtain 20 measurements.
Studdy Solution
Simon should select a random starting point between and .
Let's say he picks **7**.
Then, he measures the hand span of every **th person starting with the **7th** person.
So, he'll measure the 7th, 19th, 31st, and so on, until he has 20 measurements.
