They learn that outcomes are not so random and can actually be predicted. They realize if they relate probability to the long run, they are more likely to get the same results as someone else. They start to analyze structure and when it is know, that is probability, when it is unknown that is statistics. ]]> 2020-06-19 15:38:51 UTC https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633710784 smlyons911 https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633721652 To find probability, you need a sample space which is all possible outcomes. These can either be theoretical or empirical. The first is based on structure and the latter is based on collected evidence. At this level when collecting evidence, students can conduct basic experiments to get the foundations. No formal rules need apply at this time.  In this grade students use diagrams like trees and tables. Once students have built a strong enough foundation, students can setup their own model by hand or technology.]]> 2020-06-19 15:48:09 UTC https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633721652 smlyons911 https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633738999 The earlier grades had students analyzing data but they never thought about how the data was collected. In this grade, students determine the importance of a random sample and how if the sample is not random, it could skew the data and make it inaccurate. If the sample is truly random, statistically speaking that means it could represent a much larger group of people. By knowing this, students can expect a certain margin or error in this estimate]]> 2020-06-19 16:02:57 UTC https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633738999 smlyons911 https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633750215 Comparing different measures of central tendencies form different studies can be difficult and inaccurate. Students must make conjectures about different populations and then be prepared to defend those conjectures. Even still, there is a lot of variability that needs to be examined very closely. Means and medians collected from random samples often vary so students need to learn to take account for that variability. Simulations are the best way to find more accurate data. ]]> 2020-06-19 16:12:47 UTC https://padlet.com/smlyons911/ueiqk7tu72yjv29p/wish/633750215
