# Common Core

The Common Core State Standards Initiative is a state-led effort coordinated by the National Governors Association Center for Best Practices (NGA Center) and the Council of Chief State School Officers (CCSSO). The standards were developed in collaboration with teachers, school administrators, and experts, to provide a clear and consistent framework to prepare our children for college and the workforce.

## Inappropriate Data Usage

CC.9-12.S.ID.9 – Distinguish between correlation and causation.

## Scatter Plots

CC.9-12.S.ID.6a – Fit a function to the data; use functions fitted to data to solve problems in the context of the data.

## Using Measures of Central Tendency

CC.9-12.S.ID.2 & CC.9-12.S.ID.3 – Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

## Measures of Central Tendency and Spread for One Variable Data

CC.9-12.S.ID.2 – Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

## Measures of Central Tendencies

CC.9-12.S.ID.2 – Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

## Construct and Interpret a Cumulative Frequency Histogram

CC.9-12.S.ID.1 – Represent data with plots on the real number line (dot plots, histograms, and box plots).

## Perpendicular and Parallel Lines

CC.9-12.G.GPE.5 – Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

## Parallel and Perpendicular Lines

CC.9-12.G.GPE.5 – Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).

## Finding The Length of a Hypotenuse

CC.9-12.G.SRT.8 – Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

## Use Coordinate Geometry to Represent and/or Solve Problems

CC.9-12.G.SRT.8 – Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
