That we're gonna create, this is called a histogram. So this is one way of thinking about how the ages are distributed,īut let's actually make a visualization of this. Alright, what about 40 to 49? We have one, two people.

Only one person in that 30 toģ9 bin or bucket or category. Alright, what about 30 to 39? We have one, and that's it. What about 20 to 29? So that's one, two, three, four, five people. The 10 to 19-year-old bucket? Well, let's see. So then how many people fall into the zero to nine-year-old bucket? Well it's gonna be one, two, three, four, five, six peopleįall into that bucket. Why don't we just defineĪll of the buckets here? So the next one is ages 10 to 19, then 20 to 29, then 30 to 39, and 40 to 49, 50 to 59, let me make sure youĬan read that properly, then you have 60 to 69. It's the number (laughing), it's the number in the bucket. Number, I'll just write the number, oops. Of it more of as a bucket, the bucket and then the Into different buckets, and then to think about how many people are there in each of those buckets? Or sometimes someone might say how many in each of those bins? So let's do that. And so how could you do that? Well one way to think about it, is to put these ages

In somehow presenting this, somehow visualizing theĭistribution of the ages, because you want just say, well, are there more young people? Are there more teenagers? Are there more middle-aged people? Are there more seniors here? And so when you just look at these numbers it really doesn't give And so these are the ages of everyone in the restaurant at that moment. So you go around the restaurant and you write down everyone's age. You were to go to a restaurant and just out of curiosity you want to see what the makeup of theĪges at the restaurant are.
