By the end of this lesson your student should be able to turn a list of survey answers into a frequency table with tallies and frequencies, answer questions from it, and check that the frequencies add up to the number of responses.
🚨 Skipping an answer, or tallying the same response twice. The check is that the frequency column adds up to the number of people surveyed, and if it doesn't, something was missed.
Listing the same answer on two rows. Each possible answer gets exactly one row, no matter how many people gave it.
Do a real survey at home with five or six people, with a question that has a few possible answers, and make the frequency table on paper. The twenty answers in the lesson are made up for practice.
