Description
What It Is:
This is an 'Exit Ticket' worksheet focused on median income in the United States. It presents a table of data showing the year (from 1997 to 2006) and corresponding median income. Students are asked to determine if there is a positive or negative correlation, draw the line of best fit, write the equation of the line of best fit, and create a scatterplot using the provided data on a separate sheet of graph paper.
Grade Level Suitability:
This worksheet is suitable for grades 8-10, specifically Algebra 1. It requires students to understand scatterplots, correlation, lines of best fit, and linear equations, which are concepts typically covered in these grades.
Why Use It:
This worksheet reinforces skills in data analysis, graphing, and linear regression. It helps students understand the relationship between two variables (year and median income) and how to represent that relationship graphically and algebraically. It also provides a real-world context for applying mathematical concepts.
How to Use It:
Students should first analyze the data table. Then, on a separate sheet of graph paper, they should create a scatterplot of the data. After drawing the scatterplot, they need to visually estimate and draw the line of best fit. Finally, they need to determine the equation of that line and answer the correlation question.
Target Users:
This worksheet is designed for students learning about scatterplots, correlation, and linear regression in math classes, particularly Algebra 1. It can also be used as a review activity or as a quick assessment of student understanding.
