Pre-Algebra: Chapter 10-9 Probability of Independent and Dependent Events There are 2 kinds of probability, independent and dependent events. With independent events, like taking marbles out of a bag (but putting them back in – that is the number of … Continue reading →

Pre-Algebra: Chapter 10-8 Problem Solving Strategy Use a Simulation A simulation is an application of the Acting It Out problem solving strategy. A simulation acts out the event so that you can see the outcomes. Examples 1 and 2 on … Continue reading →

Pre-Algebra: Chapter 10, Lesson 5 Counting (we skipped Lesson 4 deliberately) We learned the Fundamental Counting Principle: If event X can occur in “a” ways and is followed by event Y that can occur in “b” ways, then the event … Continue reading →

Pre-Algebra: Chapter 10-3 Box and Whisker Plots A box and whisker plot summarizes data using the median, the upper and lower quartiles and the highest and lowest extreme values. See this link to do a few examples. It’s easier to … Continue reading →

Pre-Algebra: Chapter 10, Lesson 2 Measures of Variation Definitions: RANGE: The range of a set of numbers is the difference between the least and the greatest number in the set. MEDIAN: The middle number in a given data set. IF … Continue reading →

Pre-Algebra: Chapter 10-1 Stem and Leaf Plots Stem and leaf plots are a handy and quick way to show data trends. In a stem and leaf plot, the greatest place value common to all the data values is usually used … Continue reading →
