Graphing+and+Data

First, we looked at different types of graph. We looked at line graphs, bar graph, histograph, steam and leaf, scatter plot, pie graph,pictograph.We were also doing some graphing tasks. We had to figure out what types of graphs we need to use for each tasks. Most people used bar graph, line graph, and pie graph. We found more data, so we can work on more graphing. Like how many blocks in our class room, we can make that as a graph, how many markers, books in our class, Posters in 1F,2F,how many windows in 1F,2F, shoes in different classes, Lockers in 1F,2F.

 * First Week**

For!


 * Database Project**

Today, we looked at what a Database is. We brainstormed a list of questions we wanted to include in our Database about all the students in the school. Then, we made a survey and inserted all the names into the database.

Next, we went to the classrooms to try and gather the data. It took too long so we have to do it again. This is on-going project.


 * Feb 8 - Types of Graphs **

We brainstormed different types of graphs, and how we would use them. We did this on a googledoc. It was fun and hard, because everybody was editing at the same time! There lots of little bars with people's names on it. It was difficult to keep track of. Here is the link:

We linked our study of graphs to our study of science, motion and forces. We did a big project that involved Hot Wheels, gathering data, and graphing. Check out this link for more detail: **The Hot Wheels Project**

**Graphing Terms** We learned some important terms for graphing. Here is what they mean, and how to find them:

Mode: Mode is a number that appears most often. Like let's say the most often numbers are two 1,3. But if there is three5 the Mode is 5. Mean: Mean is an average that you added all the numbers from the data, then you divied by the number of number. Median: Median is an exact number in the middle. If youwant to find the Median, first add the number that is close to the middle number and divied it by 2. Range: Range means a number that you subtract with the first number and last number. ( First-Last )

**Box and Whiskers**

A box and whiskers diagram is a diagram that shows you the mean, and range of a set of data. It is a good way to show stats, and a good tool for analyzing. We made one with Mr Mejia from [|Yokohama International School] using [|Geogebra].
