Lesson 1: Organizing data

# Making appropriate scatter plots

AP.STATS: UNC‑1 (EU), UNC‑1.S (LO), UNC‑1.S.1 (EK), UNC‑1.S.2 (EK), UNC‑1.S.3 (EK)

## Problem

Megan wants to predict how much gas is left in her tank based on the distance she has driven. She filled up her tank and measured the amount of gas in her tank (in liters) after driving certain distances (in kilometers). Her data is summarized in the table below.
Distance (km)0100200300400500
Gas left (L)50, point, 042, point, 234, point, 226, point, 017, point, 69, point, 1
All of the scatter plots below display the data correctly, but which one of them displays the data best?
By convention, a good scatter plot uses a reasonable scale on both axes and puts the explanatory variable on the x-axis.
