Patterns in Sequences 2
This video looks again at finding the algebraic pattern in sequences. In the example, we are looking at a figure where a number of toothpicks (or lines) are added each time, and you need to find how many toothpicks will be in the 50th...

What Does it Mean To Have No Correlation?
What does it mean when a scatter plot graph shows that there is no correlation? Does it have something to do with the slope of the line of fit? Yes, it certainly does have to do with the line of fit. If the slope of the line is zero,...
