VIDEO: Algebra Applications: Data Analysis 
In this episode of Algebra Applications, students explore the dramatic events of 2008 related to the mortgage crisis. Brought about principally through mortgage defaults, the effect on the overall economy was severe. Yet, this situation offers an ideal case study for the exploration of key concepts in data analysis and probability. By exploring these questions students get a front row seat to the historical events of the world’s largest economy.

VIDEO: Algebra Applications: Data Analysis, Segment 1: Introduction 
In this introductory segment students learn about the mortage crisis of 2008. In the process they get a brief introduction to what a mortgage is. This video includes a video transcript: https://www.media4math.com/library/videotranscriptalgebraapplicationsdataanalysissegment1introduction 

VIDEO: Algebra Applications: Data Analysis, Segment 2: What Is a Mortgage? 
The time value of money is at the basis of all loans. Students learn about the key factors that determine monthly mortgage payments and use the TINspire to create an amortization table. This table is used throughout the rest of the program to explore different scenarios. This video includes a video transcript: https://www.media4math.com/library/videotranscriptalgebraapplicationsdataanalysissegment2whatmortgage A Promethean Flipchart is available for this video: https://www.media4math.com/library/prometheanflipchartalgebraapplicationswhatmortgage 

VIDEO: Algebra Applications: Data Analysis, Segment 3: What Is a What is a Subprime Mortgage? 
Having learned the general features of a mortgage, students learn the specifics of a subprime mortgage. With this comes the notion of a credit score, and with credit scores come the probabilities for a loan default. Students use the amortization table to run probability simulations to determine possible loan defaults on subprime mortgages.

VIDEO: Algebra Applications: Data Analysis, Segment 4: What is an Adjustable Rate Mortgage? 
Another factor in the mortgage crisis was the use of adjustable rate mortgages. Students run a number of scenarios to test adjustable rate mortgages, while also taking into account the state of the housing market during the time of the mortgage crisis.

VIDEO: Algebra Nspirations: Data Analysis and Probability 
What are the two meanings of statistics? What does it really mean that an event has a 50% probability of occurring? Why are data analysis and probability always taught together? Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video answers these questions and addresses fundamental concepts such as the law of large numbers and the notion of regression analysis. Both engaging investigations are based on true stories and real data, utilize different Nspire applications, and model the seamless connection among various problem representations. Concepts explored: statistics, data analysis, regression analysis.
