# Mathematics

The abstract science of number, quantity, and space.

## 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.
