OBJECTIVE - S.CP.A.5

Recognize and explain the concepts of conditional probability and independence in everyday language and everyday situations. For example, compare the chance of having lung cancer if you are a smoker with the chance of being a smoker if you have lung cancer.

INTERPRETATION OF OBJECTIVE - S.CP.A.5

This objective basically has students look in the world around them and look for real world situations that involve conditional relationships and independence.

SKILLS

(1) The student will be able to recognize the concepts of conditional probability based on everyday language and everyday situations.

(2) The student will be able to recognize the concepts of independence based on everyday language and everyday situations.

THE BIG IDEA

The world around us is based on the interaction of many things and with a little data and analysis we can begin to see conditional and independent relationships.

TRAPS & PITFALLS

The only thing I could think of is that the data may imply a certain relationship and yet there may be other variables at play that are not directly obvious to the student.

PAST CONNECTIONS

The student needs to use the foundational concepts of conditional probability and independence to investigate real world situations.

FUTURE CONNECTIONS

Apply what we have learned so far to the real world.

MY REFLECTIONS (over line l)

This objective is still a little too unclear for me. I'm not exactly sure what this looks like. I think it is the process of students choosing some items that seen to related and not relate, gather data and then look at independence between them. They could store the data in a two-way frequency table and then apply the tests for independence.
