00:00Hello, and thanks for joining me today, guys.
00:07We are going to learn about bar graphs.
00:09If you look right here, you can see that we have some fruit.
00:13I wanted to know what types of fruit my friends like, so I went out and asked my friends what
00:19fruit they liked the most.
00:22Here you can see that I have tally marks to show how many of my friends liked which fruit
00:26most.
00:28You might know already, but a tally mark is a useful way to represent data.
00:33Each time a friend told me they liked a certain fruit, I would put a tally mark under that
00:37fruit to keep track of how many people liked that fruit.
00:43Now we will put all this information that I have gathered into a bar graph.
00:48A bar graph is another way to represent data.
00:51It is a lot like a picture graph, but without the pictures or symbols.
00:56Here is our graph, but the first thing we need to do with any graph is what?
01:02We need a title.
01:03Since the information we collected was on favorite fruits, let's call it favorite fruit.
01:11With this graph, I want to put the names of the fruit on the bottom, and the numbers on
01:15the left side going up.
01:19We can see here on the bottom, we have the names of the fruits.
01:23We should label what these are.
01:25This is obviously going to be labeled fruit, since they're fruit.
01:30On the side, we need to measure how many people liked these different types of fruit.
01:35We only need to go up to 6, since our information or tally marks only go up to 6.
01:41So the numbers going from 1 to 6 represent the amount of people.
01:46We can now fill out the graph according to our data.
01:50First in our data are the apples.
01:52We can see from the tally marks that two of my friends liked apples.
01:57So here on the graph, we will have this bar at the bottom go up two spots to show that
02:02two people liked apples.
02:06Okay, next we have oranges.
02:10How many people liked oranges?
02:15Good job!
02:16Three people liked oranges.
02:18So we move the bar up to where the three is.
02:22Now how many people liked pears?
02:27We had just one that liked pears, so the bar goes up just one.
02:33The last one is bananas.
02:35There were six people that liked bananas, so the bar goes all the way up to six.
02:42We now have an amazing bar graph that shows all of our data that I collected about what
02:46is the favorite fruit to eat.
02:49With this graph, it is easier to read and interpret the information.
02:54For example, I can see that only one person liked pears.
02:57Now that's interesting.
03:00Can you tell me what fruit was the most popular?
03:05We can tell from the graph that bananas were the most popular.
03:10Can you guys tell me how many more people liked bananas than oranges?
03:19Looking at the graph, we see that six people liked bananas and three people liked oranges.
03:25Counting up the graph from three oranges, we count one, two, three spots.
03:31There are three more people that liked bananas instead of oranges.
03:37We can learn lots of cool information from this graph.
03:40Practice doing your own bar graphs and compare the information you collect.
03:44We'll see you next time.
