Experimenting with Geogebra

Page 269, questions 1-4

This is what I did on Geogebra. First I made points on (0,0) and (3,0). After connecting them, I put the angle number that I wanted which was 34º. Then it automatically put the point R. After connecting them I saw that the RQ segment wasn't correct and it wasn't 90º, so I put a ray from QA, so that there would be an intersecting point from PB to QB. 
1a) QR = 4.0m
1b) PR = 7.2m

I started by making a scale, 1m = 10cm. I put a point at (0,0) and (7,9,0). Then I put the angle that measured 33º. Then I created a ray from point A to B, and made a new point right above point B which was called point C. I created a ray from BC, which later I found the point of intersection. 
The height of the flagpole was 5.13 cm, or 51.3m

First I created a scale, 1m = 1 cm. Since XY is the longest side I figured it is the hypothenuse. After plotting all the points, I connected all three together then I clicked on the 'angle' button and figured the angles. 

Scale: 1cm = 100m
Then I put the points (0,0) and (4,0). I then put point C anywhere because I would have to move it anyways. I then connected the points together so that there was a triangular shape-ish. The next step was to input the angles, and after I did that I moved point C around so that the angles would correspond. I believe my answer is wrong because I moved point C around and it wasn't precise. 

How would this work if we didn't have Geogebra? What would our answers be like if we used protractors and rulers?
I believe the answers would be similar, because the only thing that Geogebra does is make the drawings more precise. If we did it on paper with protractors and ruler we would only have human mistakes, because the idea is the same.

 My question was if characteristics such as age, gender, and others affect your score on Flappy Bird. I found out that age affects the high score, because older people tend to not have a lot of time, comparing to younger people. At the beginning of my project, I had decided that I would have teacher and student scores, but as I was looking for people it became harder and harder for me to find people who were willing to help me. Instead of having a huge gap between student's and teacher's ages, I focused my project on teenagers. I did my experiment with the high schoolers, that were 14-18 years-old. I found out that high schoolers have almost the same high score. I believe this is because everyone played on a Galaxy Note II, which is not common around Graded. Most people never played Flappy Bird on a Galaxy Note (which is 2x larger than any other smartphone), so their high scores would be pretty low. I had predicted that the results wouldn't vary a lot. Although the results didn't vary a lot, there were some outliers. Those outliers were people in between the ages 14-15. 
One of the things I discovered was that 18 year-olds discovered Flappy Bird in Vines. I believe they first heard of it in Vines, because they are short and easy to access, while the 14 year-olds discovered the game through friends. I believe that 14 year-olds have more time to socialize with friends, and 18 year-olds have less time because they are probably seniors. Vines are easily accessible and are very entertaining, so people can watch some vines during their breaks. 
I did this experiment as a curiosity, and I don't think this information was useful. Now that I look back at my project, I believe that another thing I could have done is used different types of smartphones. A "better" topic question could be, "Do different types of smartphones affect high scores?

Interpretation of Results

For this graph, I separated the people into two groups, the ones who preferred math or english. I did a pie graph, because it is easier to see the percentages of people. From this graph, I discovered that most people discovered it from vines and friends. I believe people discovered it from vines, because they are short videos that people can have easy access to. One possibility for why some people discovered it from friends, is that they might have seen their friends playing.
For this chart, the x-axis were the ages. To understand the chart a very important key would be the key at the top right corner. It tells what color is what. Although the colors are not that visible, you can tell a slight difference. The point of this chart was to see how many people from each age group discovered Flappy Bird through Facebook, Vines, Tumblr or through friends.  Most of the 14 year-olds discovered Flappy Bird through their friends. I think a reason why they found it through friends, is because they might hang out a lot with them, therefore socialize a lot. The people who found the game through friends have most likely watched their friends play Flappy Bird. 
While 14 year-olds have found Flappy Bird through friends, most of the 15 and 16 year-olds have found Flappy Bird through Facebook. I believe that people between ages 15 and 16 spend most of their time on Facebook looking at the newsfeed. 
Younger people (14 year-olds) tend to not see vines too much, although the 18 year-olds tend to watch more vines. I believe older people watch more vines because they are short and easily accessable. 
This graph shows that half of the people I questioned preferred math or english.

Data Collecting Process

For my project I chose to do an experiment on Flappy Bird with four trials. Three of the trials were with no distractions, while the last one was with the Flappy Bird sound. I chose five people from both genders that are 14,15,16,17,18 year-olds, and fifty teachers between the age 30 and 50. I got my data by going around the campus and asking people questions.
Some of the questions I had were, "How many siblings do you have?", "How many hours of sports do you do per week?", "How much time do you spend on the internet? Not counting school-related stuff", "How did you "discover" Flappy Bird?", and, "Do you prefer Math or English?". These questions were for the students.

Statistics Project

After our summer break, the first major assignment that Ms. Ange gave us was a statistics project. For this project, we will have to collect data and making a conclusion out of it. Our teacher gave us the option of choosing what we were going to do. We could collect data by doing an experiment or doing a survey. I chose to do an experiment to see if any characteristics (age, gender, teacher/student) make a difference on 'Flappy Bird' highscores.

Pascal's Triangle

In class we learned something new called Pascal's Triangle. To make the "triangle" you start with a 1 and end with a 1. In the triangle, we have horizontal sums, diagonals, odd and evens, and exponents of 11.

Unit 1 Test Reflection

In the Unit 1 test I did pretty well and got an average grade. I got five questions wrong, because I did silly mistakes. In one of the questions I distributed it wrong and put the wrong -/+ sign. The first part of the test we had to solve for x and I got three questions wrong on that section. I wish I had payed more attention to the questions so that I could have gotten a better grade.
Another question I got wrong was number 14, which was about speed/distance/time question. I had gotten it wrong because I used the wrong formula. If I had studied it better (and memorized the formulas for distance, speed) I would have gotten the question right.
