Final answer:
To randomly assign half of a group of students to a treatment group, assign number labels to the students and use a long string of random digits to select groups of students.
Step-by-step explanation:
To randomly assign half of a group of 100 students to a treatment group, you can use a long string of random digits. Here's how:
- Assign consecutive number labels to all the students, starting with zero.
- Break the long string into chunks of digits.
- Select the chunks of digits in pairs, triples, or any other size as specified. Each chunk of digits represents a group of students.
