Answer 1

Correct answers:
- True: "Dot plots are best used to show a distribution of data." — A dot plot displays each observation as a dot along a number line so you can see shape, center, gaps, and outliers.
- True (in a limited sense): "Dot plots are best used to help you tally data." — Dot plots effectively show counts (each dot = one observation), so they’re useful for tallying or summarizing collected data.

Incorrect:
- "Dot plots are best used to show answers to a non-statistical question." — Not really; dot plots display quantitative or categorical data, not the “answer type” of a question.
- "Dot plots are best used to help you ask questions." — No; they help you analyze and display data, which can lead you to ask questions, but they don’t directly help you formulate questions.
