Statistics intro: If you had to represent this data with one number. Calculating mean and median from data displays. So this is our mean. Then finally, we can think about the mode. The middle. So 23 and a 23.
So it looks like the smallest number here is 20. Then, the next one is 21. Median in a histogram. Actually, I'll just get the calculator out for this part. If you're seeing this message, it means we're having trouble loading external resources on our website.
And so it's one way of measuring the central tendency. And then we want to divide 206 by 8. So the sum of all the numbers is 206. If you have an even number, there's actually two numbers that qualify for close to the middle. And this is another way of representing the middle. And no 24's. That, by itself, can't be the median because there's three less than it and there's four greater than it.
Another way is with the median. So if I say 206 divided by 8 gets us 25. So we have 23 plus 29 plus 20 plus 32 plus 23 plus 21 plus 33 plus 25. Up Next.
There's no 26, 27, 28. And they give us the numbers right over here. And then you have your 33. So this is the middle number. So the mean is equal to 25. So if someone just says the mean, they're really referring to what we typically, in everyday language, call the average. And 25 by itself can't be the median because there's three larger than it and four less than it.
