“The key takeaway is that correlation is an understandable equation that relates the amount of change in x and y.  If the two variables have consistent change, there will be a high correlation; otherwise, there will have a lower correlation.    ”

“liter. The correlation value, r, will be the same for either set of units.  Note however that the slope of the regression line won’t be the same since And the standard deviation parts of the equation still have units baked into them.     Correlation Takeaways We did a lot of looking at equations in this section.  What are the key takeaways? The”

“An important thing to know is that there will always be at least as many permutations of a set as combinations, and typically many more permutations than combinations.”

“Permutations are what you use when the order matters. For instance, if 8 people are racing in a track meet, and you want to find the different ways they could get 1st, 2nd, and 3rd place, then the order matters. So you would use a permutation. Combinations are what you use when the order doesn’t matter. For instance, if you have 10 different pieces of clothing you want to take on a trip, but you can only fit 7 of them in your suitcase, it matters which 7 you pick, but it doesn’t matter what order you put them in the suitcase, so you would use a combination”
