## ◂Math Worksheets and Study Guides Eighth Grade. Collecting and describing 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.
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.
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).
A2.D.1.2. Collect data and use scatterplots to analyze patterns and describe linear, exponential or quadratic relationships between two variables. Using graphing calculators or other appropriate technology, determine regression equation and correlation coefficients; use regression equations to make predictions and correlation coefficients to assess the reliability of those predictions.
