WHAT happened on friday?On Friday, we used the TI cc2650 SensorTag a little bit just to get used to it. On Monday we will be getting more in depth with it. What is the sensortag?The TI cc2650 SensorTag is a sensor made by Texas Instruments to record Light, Temperatures, Motion, etc. The ones in the class have a problem with motion. What did i do with the sensortag?When me and Khalil (my partner) got hold of the SensorTag and got it working, we did some activities with it. We put our hand over it and looked the light amounts drop, we blew on it and watched the IR Temp raise (I somehow got it to 945 degrees Fahrenheit. I've got some hot breath, don't I?). We also put it against the computers to see how warm they were. I had a lot of fun using them on Friday. How will i use the sensortag?I will use the SensorTag on campus by testing the Temperature with different light levels. But, we can also use it to test things like plant growth with different temperatures and things like that.

What happened last time?I did not realize that we had a blog post last time we did. Mr. Bourgeois had a substitute, and wrote it on the board. Oblivious mode kicked in and I didn't notice. I also didn't check Schoology. What an ignoramus I am! The importance of Data VisualizationThe title came out weird for this one, but anyways, we use data visualization in many ways. From Math to Economics, we use a type of visualization called Graphing, or putting information on a plane in a specific way called Graphs. There are many different types of graphs, but the 3 main ones are Line Graphs, Bar/Column Graphs, and Pie Graphs. It is important to me, because if I want to become a Game Designer or a Computer Scientist, I will need to know how to use many more graphs than listed. I will need to graph things like incomes, outcomes, death rates, difficulty, etc. But before I tell you how I would use them, I'm going to tell you a little about them first. Line GraphsLine Graphs are used to record trends in data. For example, temperature is usually represented by line graphs, and so is money and economics. Growth and Grades are shown by them as well. Line Graphs consist of a title, Legend (in some cases), X & Y-Axes, Labels, and a line (or multiple depending on the data being represented). The X-Axis represents the Independent Variable (or changed part) of the data on each point of the line, while the Y-Axis represents the Dependent Variable (or result of the change) on each point of the line. We use these in modern day to keep track of money, growth, population, etc. Bar/Column GraphsBar Graphs are usually used to compare different sets of data within the same experiment. Column graphs do the same, except look different. Column Graphs go up and down, while Bar Graphs go left and right. We use these to record specific events, like "Average Temperature Per Month" or "Amount Plant A Grows in a Month Compared to Plant B" (that probably won't be an actual title, but you get the point). There are many different types of Bar Graphs. For example, there are Histograms, which show data in the form of intervals. There are Grouped Column, which show different components, like "Growth Based on Rainfall and Height" compared to each other, then compared to other sets of Grouped Columns. There are Stacked Columns, which shows a whole bunch of data joined into one column. Components of a Bar Graph include the Title, Axis Title, Intervals/Labels, Tick Marks (in some cases), X & Y-Axes, Grid, and Bars/Columns. On Column Graphs, the x-axis includes the intervals (in a Histogram), and the labels for units of the Independent Variable/Category. On Column Graphs, the y-axis includes labels for the dependent variables. An example of a Column Graph title would be "How high a Pea Plant and a Corn Plant can grow in One Month". On Bar Graphs, the x-axis includes units for the Independent Variable. On Bar Graphs, the y-axis includes labels for units for the Independent Variable/Category. In example of a title for a Bar Graph would be: "How Long Will it Take for a Sunflower to Reach 5 Feet Tall?" Pie GraphsPie Graphs are used to represent parts of a whole. They usually consist of a Legend, different colors, a "pie" (or a circle cut into different parts), labels and their corresponding percentages. We use them in our country to compare Culture Population, Diversity in Schools, Grades among different genders, etc. An example of a title for a pie graph would be "What percentage does each race make up in the United States?" Using Graphs to change societyWhen we use graphs, we usually have a purpose for it. Either it is to show a specific pattern on you math homework, or it's to show spawn rates for the new event in Pokemon Go, we always have a purpose. There are even bigger purposes to graphs, than just homework. Our Government uses them to show economics and make sure we stay out of even more debt than we're already in. They also use them in the Stock Market to show the change in the price of stock in each business. I'd use it to show our economy before, during, and after Trump's presidency (and I'm sure it isn't gonna look good). I'd also use them to see how many women would vote for Trump before and after I showed them a video of his sexist remarks and rape claims and see the change.
