Question

two - variable statistics: unit 3 review
this table shows the latitude and high temperature on december 25, 2017 for 12 cities in the united states.

construct a scatter plot for this data set.

describe any relationship between the latitude of a city and its high temperature on december 25, 2017

Explanation:

A scatter - plot is a graph that shows the relationship between two variables. Here, the two variables are latitude (on the x - axis) and high temperature (on the y - axis). Each city is represented as a point \((x,y)\) where \(x\) is the latitude and \(y\) is the high temperature.
Looking at the data:

• As the latitude (a measure of how far north a city is) increases, the high temperature on December 25, 2017, generally decreases. For example, Miami (\(26^{\circ}N\), \(83^{\circ}F\)) is at a lower latitude and has a higher temperature, while Minneapolis (\(45^{\circ}N\), \(5^{\circ}F\)) is at a higher latitude and has a lower temperature.

Answer:

There is a negative relationship between the latitude of a city and its high temperature on December 25, 2017. As the latitude (northward position) of a city increases, its high temperature on that day tends to decrease.
