# 2D & 3D Geometry

#### Unit 7 focuses on Statistics, focusing on differentiating Measures of Center and Measures of Variability. In this unit, identifying and forming Statistical Questions is a focus, while understanding how to Summarize Data and understand their Distribution Shapes. Measures of Center such as Mean, Median, & Mode, and Measures of Variability such as Range, I.Q.R., & M.A.D. are covered in detail. Furthermore, data sets are summarized using Quartiles with Box Plots, and Frequency Tables & Histograms.

 7.1 Statistical Questions & Data Shapes 7.2 Calculating Measures of Center & Variability 7.3 Using Box Plots to Summarize Data 7.4 Using Histograms & Frequency Tables to Summarize Data

## 7.1

#### Statistical Questions & Data Shapes

This lesson is designed to help learners identify and construct Statistical Questions and understand the main Distribution Shapes of collected Data as Centered, and Skewed Data sets.

## 7.2

#### Calculating Measures of Center & Variability

This lesson is designed to help learners differentiate Measures of Center (Mean, Median, & Mode) and Measures of Variability (M.A.D. & Range) and Calculate them to summarize a data set.

## 7.3

#### Using Box Plots to Summarize Data

This lesson is designed to help learners understand how to take a data set and summarize it using a Box Pot using a 5-Number Summary, while also calculating the threshold for outliers. The 5-Number Summary includes the Minumum, Lower Quartile, Median, Upper Quartile, and Maximum. In addition, the I.Q.R. is calculated as a Measure of Variability.

## 7.4

#### Using Histograms & Frequency Tables to Summarize Data

This lesson is designed to help learners understand how to take a dataset and summarize it using a Frequency Table and Histogram. Data is sorted into Intervals/Bins, and their Frequency is measured along the Vertical Axis. Data Distribution Shapes are discussed, as well determining which Interval the Median is located within.
