Lesson Transcript
Instructor: Yuanxin (Amy) Yang Alcocer

Amy has a master's degree in secondary education and has taught math at a public charter high school.

In math, when we have to deal with a lot of data, having a visual format to present all the data becomes very useful. Watch this video lesson to learn how you can take advantage of two of these visual formats.

## Ways of Organizing Data

When it comes to organizing data, there is no shortage of ways to present it. Just look at different shopping catalogs and you can see the different ways that data is presented. Your school schedule itself is an example of a way to organize data. All of these ways show you useful information in an organized and easy-to-understand manner.

Why do we have visual ways of organizing data? We have all these different ways of organizing our data so that we can better understand our data. If our data were written down randomly with no order, then we wouldn't be able to make much sense of all that information.

Take your school schedule, for example. If it was written out of order, would it help you to get from class to class throughout the day? It probably wouldn't. You'd probably get lost somewhere trying to make sense out of it. It is the same with all the other data that we have to deal with.

## Tables and Schedules

And that is why in this video lesson, we are going to discuss two ways we can present, or otherwise organize, our data. We are going to talk about tables, data organized into rows and columns, and schedules, a special table for listing times and events. We will see how to create tables and schedules from data we have already collected, as well as how to read them.

We actually see tables and schedules all around us. Your school schedule is a perfect example of a schedule. A shopping catalog is a perfect example of a table that we see and use often in real life. Creating and organizing tables and schedules is actually not all that difficult. Reading and understanding them is fairly straightforward and easy to do as well. So, let's get going and see how we can create and then read a table.

## Creating and Reading a Table

Say we had a list hidden in one of our sock drawers where we wrote all the items we ever wanted if we could afford it. It also has the prices of the items written down. We also made a note of where to buy the items from when the day came that we could afford them. The items include a convertible for \$80,000 available at the local car dealer, a Great Dane puppy for \$2,000 available from the local breeder and a dream vacation island home for \$500,000 available from the realtor.

To write all this information down in table form, what I need to do first is to decide what kinds of information I have. I see that I have an item type, item price and where to purchase the information. I begin creating my table by writing my kinds of information all on one row, leaving just a bit of space in between so I know that they are separate pieces of information. I draw a line underneath, as well as vertical lines to separate my kinds of information.

Item Type Item Price Where to Purchase

My next step is to fill in my table by writing the information for my items one line at a time. I use one line for each item. So, if I begin my second line by writing 'Convertible,' I will write down the other information for the convertible in the other two spaces that are left on that line.

Item Type Item Price Where to Purchase
Convertible \$80,000 Local Car Dealer

I continue with my other items until I have filled in my table completely with all my data.

Item Type Item Price Where to Purchase
Convertible \$80,000 Local Car Dealer
Great Dane Puppy \$2,000 Local Breeder
Dream Vacation Island Home \$500,000 Realtor

Once I have written down all my data, I am done creating my table. That wasn't so hard, was it?

To read our table, we can easily scan it to find the information we are looking for. Say we wanted to find the cost of our vacation home. We look at our table and look for the line where our vacation home is written down.
