## ◂Math Worksheets and Study Guides Eighth Grade. Using graphs to analyze data

### The resources above correspond to the standards listed below:

OK.PA. Pre-Algebra (PA)
PA.D. Data & Probability (D)
PA.D.1. Display and interpret data in a variety of ways, including using scatterplots and approximate lines of best fit. Use line of best fit and average rate of change to make predictions and draw conclusions about data.
PA.D.1.1. Describe the impact that inserting or deleting a data point has on the mean and the median of a data set. Know how to create data displays using a spreadsheet and use a calculator to examine this impact.
PA.D.1.3. Collect, display and interpret data using scatterplots. Use the shape of the scatterplot to informally estimate a line of best fit, make statements about average rate of change, and make predictions about values not in the original data set. Use appropriate titles, labels and units.
OK.A1. Algebra 1 (A1)
A1.D. Data & Probability (D)
A1.D.1. Display, describe, and compare data. For linear relationships, make predictions and assess the reliability of those predictions.
A1.D.1.2. Collect data and use scatterplots to analyze patterns and describe linear relationships between two variables. Using graphing technology, determine regression lines and correlation coefficients; use regression lines to make predictions and correlation coefficients to assess the reliability of those predictions.
A1.D.2. Calculate probabilities and apply probability concepts.
A1.D.2.2. Describe the concepts of intersections, unions, and complements using Venn diagrams to evaluate probabilities. Understand the relationships between these concepts and the words AND, OR, and NOT.
OK.A2. Algebra 2 (A2)
A2.D. Data & Probability (D)
A2.D.1. Display, describe, and compare data. For linear and nonlinear relationships, make predictions and assess the reliability of those predictions.
A2.D.1.1. Use the mean and standard deviation of a data set to fit it to a normal distribution (bell-shaped curve).
