Counting on True / False Quiz
The Fundamental Counting Principle comes up in questions where you are asked the number of ways to answer questions on quizzes. Basic problems can be answered with a tree diagram. However, more complicated questions may require you to use a slot diagram.
Finding Equations of Lines
In this post, I’ll demonstrate how we can use y = mx + b to find equations of lines. No need to memorize other equations of lines…it is easier to focus on the data given to us an use it to find m and b.
How Do You Find Statistics from Frequency Data?
Working with frequency distributions to find the mean, variance, and standard deviation can be a little tough. In the example below, we’ll incorporate Sheets (or Excel) to make it easier to calculate these statistics. An example is worked out in Example 3 of Question 2 in Section 6.2 for the mean and in the video below for standard deviation.
Let’s look at how we can implement this process in a spreadsheet.
