To see a lot of examples, and frankly, you should too because it'll help you test your knowledge. I'm using Khan Academy exercises because it's a good way So I'd call thisĭistribution right-tailed. But here when we have a few people between 60 and 70, evenįewer between 70 and 80, even fewer between 80 and 90, and you know, if it just kind of keeps going like this, this is a tail and it's on the right side, it's a right-tailed distribution. So this distribution right over here, it looks like it has a tail to the right. We actually use those types of words to describe distributions. If you were to imagine this were an armadillo, this would be the body of the armadillo, and then what we see to the right kind of looks like the So just when you lookĪt something like this, a distribution like this, something might pop out at you. Have a reasonable number between 20 and 30, we have a lot of guests at 30, in that bucket between 30 and 40, reasonable number between 40 and 50, and then as we get older, we have fewer and fewer guests. So we don't have any guests that are under the age of 20, we In each bucket, it tells us the number of guests that are in that age bucket. So right over here, let's see, we're talking about Matt's Cafe, and we have different age buckets, so this is a histogram here. Want to talk about now are shapes of distributionsĪnd different words we might use to describe those shapes.
