Jared is interested in finding out which of two types of soda are preferred by ​students at his school.
​
​Explain how he can randomly choose fifty students to ​participate in a survey or an experiment.
​
​Then describe how both a survey ​and an experiment can be designed for the purpose of answering his ​question.

Answer 1

How to pick 50 students (randomly, simply)
- Get a complete list of all students (roster).
- Number them 1 to N.
- Use a random-number generator (phone/computer) to pick 50 distinct numbers, or put all names in a hat and draw 50.
- Those drawn are the sample.

Simple survey design
- Give each chosen student a short anonymous questionnaire: “Which do you prefer: Soda A or Soda B?”
- Give clear instructions and present the two sodas (or pictures) in a neutral way (order randomized if possible).
- Record answers and report percentages.

Simple experiment (blind taste test)
- Bring both sodas in identical unlabelled cups.
- Randomly assign each student an order (A then B or B then A) to avoid order effects.
- Have them taste both and say which they prefer (or rate each).
- Record results and compare counts/percentages.

Quick notes: ensure voluntary consent, keep it anonymous, and use the same serving size/temperature for fairness.
