There are 44 test scores from students and I am ask to analyze the data using different methods of graph. Talk about advantages and disadvantages of each graphs lastly describing the “Middle” and the “Spread” of the compiled data and how is it significant overall. There are many different types of graphs mathematician can use to compiles data to help them get a better understanding of everything by seeing it visually before start doing all the calculation and draw conclusion. The 4 types of graphs that I am focusing on this test scores from students are Stem-and-leaf, Histogram, Pie graph, and Box-and-whisker. Stem-and-leaf
The advantages for this graph is that the data can easily be seen clearly. All the test scores are put in order from

This makes the graph neater because everything is in an equal interval instead of every single individual data which could make the histogram too long. One of the disadvantage for the histogram is that the x-axis is in interval so you do not get to see the details in each interval. For example in this data, it is nice to see that a good amount of students make a 80s and 90s as well, but you do not know how many are in each intervals. It could be that there are three kids make an 82 and seven kids make a 81 on their test. We do not get to see the details on how low or high 80s they got on their …show more content…
It also show 4 different quartiles to let the teacher know the lowest, middle, and highest grades the class is in. This graph also show how much spread out the data is on the number line. After drawing the box-and-whisker for this data, you can see that the lowest grade is a 35, middle grade is a 78, and highest grade is 86. The box from 67 to 86 represent that most students fall into that range on their test. The disadvantage this graph have is like the other two graph, you cannot see the individual test
After completing the matching portion, the students will then answer four questions. The first question will ask the students to write down any similarities they notice in the graphs. Next, they will answer what differences they notice in the graphs. Thirdly, they will describe how they labeled the independent and dependent quantities in each graph. Lastly, they will analyze each graph from left to right and describe any graphical characteristics they notice.
(Graph below would be posted using the PowerPoint for students to see before open discussion
Next the best method of comparing the data needed to be choses to best understand the information of the two years. What the students came up with was. “The Mode is the option in this scenario
Then, a scatterplot was formed with the data (Figure 3). It was a crucial graph as it helped determine the outliers in the information (see Appendix D for the outlier chart). Some of these outliers were located in towns with really low population numbers (the average population for an American city or town is around 20000)
The grade scale method is important because it’s away that the students are able to see how they are doing in the course. Its important that students are able to see their actual percentage grade because that gives the students the opportunity to see how they are doing in their course and also it gives them the opportunity to see what exactly did they pass or fail and what areas they need to improve. Grades are better at telling students how they are doing in the course because in the case of the pass-fail scale all the students have to rely on is a letter grade that can possibly mean ten different percentage grades. When you have a student who receive a grade of 85 he/she understands that they have a B but more so they are able to see what they need to improve on in that area of the course to bring it up to an A compared to the pass-fail scale where the student is just receiving the letter grade of a B they will assume that whatever they are doing is good enough to get them by in the class when it could possibly mean that they can be declining in there grades because a B can either mean you are one point away from a C or one point away from an A. The grade scale method is important for the simple fact that student is able to see how they are doing in the course.
The grade scale furnishes students with superior achievements the opportunities to receive Scholarships. The grade scale allows professors and colleges to average a point value for academic reviewing. The chart below shows the different level of achievement for a grade scale and a pass/fail scale. The grade scale f...
The two columns in the graph represent the mean values and the error lines represent the standard deviations of the tested grasshopper and human subject. The jumping distance of the grasshoppers was more than the jumping distance of humans and the TTEST value was less than 0.05.
There are two histograms, showing information on GPA, and showing information on final grade. Histograms are commonly used with interval or ratio level data (Corty, 2007). The data in the GPA is distributed and slightly skewed to the right, which means it has a positive skew and has a peaked distribution. The final histogram also has a leptokurtic frequency distribution, but is skewed to the left meaning this has a negative skew.
As what can be seen in the data part of the report, the given values for x and y can be interpreted as a graph. With this graph, it can be interpreted to describe the phenomenon that is taking place. This is how graphs and equations can help the study of science understand how and why things are taking place.
If you already know what a binary tree is, but not a general tree, then pay close attention, because binary trees are not just the special case of general trees with degree two. I use the definition of a tree from the textbook, but bear in mind that other definitions are possible.
Social media has become a major epidemic in today’s society. According to millions of people have signed up on social media websites, allowing their basic information to be shared with the world wide web. Two of the biggest social media websites today are Facebook and Twitter. The new generation tends to use Twitter over Facebook, the older generation prefer Facebook over Twitter. Though Facebook and Twitter serve the same purpose and have many similarities, they both differ in many ways.
Assessments should be aligned to learning objectives. The assessment we administered was designed to measure students’ thinking about data. Common Core standard 3.MD.B3 asks students to draw a scaled graph to represent a data set with several categories. Solve one-and two-step “how many more” and “how many less” problems using information from the table (Council of Chief State School Officers, CCSS, 2010). The main purpose of this assessment was to evaluate student knowledge about graphs. We also wanted to know if students were able to compare and contrast information in the graph. We think that this is an important skill that students should be able to master. Students will encounter graphs while learning about other subjects. They must know how to collect data and use the information from gra...
One of the most popular types of charts is the pie chart. The pie chart is used to visually represent the proportional value of individual parts to the whole. As the name describes, this is done by representing the numerical equivalence of each part as a piece of the whole pie, which in total equates to 100%. The Pennsylvania Department of Health (2001) says that pie charts are a good choice when a relatively small amount of parts, perhaps 3 to 7, need to be represented. With any more it becomes difficult to notice the differences in magnitude; thus, the pie chart loses its simplicity and impact. They can only be used when a total amount is known, one such example would be an election where the total of votes received by all candidates equals 100% of the votes. Or a budget where the total amount spending is divided in to categories such as labor, facilities costs, advertising, etc… which always are a part of the total. However, according to McBride (2003), the pie chart could not be used to show a change in spending through out a period. A pie chart shows data at one instance, like a snapshot and cannot be used to show change in data over time (para. 4). With the advent of computers, 3D graphs have become somewhat popular, unfortunately a negative aspect is that they add complexity to the image and can distort visual proportional value. It is recommended to stick with flat “2D” charts (para. 6).
Technology has changed modern society drastically, both positively and negatively. Technology has influenced every aspect of our life, making it simpler but not necessarily better. Albert Einstein was concerned about the advancement of technology. "I fear the day that technology will surpass our human interaction."1 Undoubtedly, what has changed the most are communication, the spread of information, and how business is practiced. Consequently, practically everyone knows how to use a computer, connect to the Internet, or use a smartphone. This is demonstrated by the way the Internet is used daily by millions of people to communicate, to sell, advertise, retrieve, and share information. Thanks to the Internet, information from anywhere in the world is at our fingertips. As a result, the advancement of technology has changed our life in many ways including; sharing of information, communication, business, education, social interaction, simplifying everyday tasks, replacing basic skills and jobs.
Evidence from both educational journals and personal interviews suggest several different possible approaches to successful science integration. Many of the lesson plans dealt with integrating science with technology or with mathematics. For example, a fifth-grade teacher had his class record weather observations for an entire year and then used their data to teach graphing concepts including bar graphs, line graphs, pie charts, as well as concepts such as mean and mode (Chia, 1998).
