I decided to choose to do my project on if the gender of the teacher reflects what the student gets in the class. I am interested in this because I feel that a male teacher, for me, does a better job teaching. They have a stronger personality and are louder which keeps you listening. I chose to do this project because I am interested in seeing how the average student feels compared to how I feel. In order to collect my data, I will test a total of 10 classes, 2 classes from the following subjects; Algebra 2 regular, Chemistry Honors, IB History, Media Arts, and English 10 Honors. One class will be from a male teacher and the other from a female teacher. I will the split the classes into two groups male and female. In the two groups I will categorize the 5 classes into what the student got in the class. There will be 5 categories A, B, C, D, and F. Since I only want 5 columns I will round the A-'s, B-'s, C-'s, and D-'s to a regular letter grade. As well as the A+’s, B+’s, C+’s and D+’s to a regular letter grade.

After obtaining all the data, I will begin to compare and analyze the data. First, I will do a simple process by finding the mean, median, and mode of the two groups. Since my data is in letter grades I will have to change the letters to a GPA. For example an A would be a 4, also since I am rounding the A-'s to A's an A- would also be a 4. Finding the mean, median and mode will show what the average grades are in the male and female classes. That data can be compared easily to show what grades are getting in which gender class. Another simple mathematical process is making a histogram. Each category (A, B, C, D, and F) will have two bars coming from it, one male and one female. This can show how many of the each letter grade is coming from each gender. It will visually show what gender is getting what grades in the classes. The last mathematical procedure I will be doing is a Chi-squared table which will be my...

Introduction/Purpose
Predictability is the degree to which a correct prediction or forecast of a system’s state can be made quantitatively. It is necessary to achieve maximum productivity or potential when completing a task. The ability to foresee an occurrence before others allows one to alter different aspects in time to garner the utmost productivity. The question that has been plaguing today’s generation is the use of social media sites, and their consequences on our lives. A restaurant only orders an amount of food adequate for its needs. If the restaurant orders more than it needs, then the extra food will spoil and the restaurant will lose some of its inventory. A trader that has inside information on a corporation may sell his stock minutes...

...likelihoods of making Type I and Type II errors.
An experiment where you may want a lower alpha level (e.g., 0.01) would be for example a drug study for coagulation times. You would want to be certain the drug is effective, therefore a lower alpha level would be prudent. Within this same drug study, you would accept a higher alpha level when looking for drug side-effects. (University of Texas-Houston Health Science Center , 2013)

How would you explain the analysis of variance, assuming that your audience has not had a statistics class before?
When examining the differences between two or more groups, you can use the analysis of variance which is known as ANOVA. This is a statistical technique that is used to compare the means or averages of more than two groups. There are three uses of ANOVA which are the one-way, the two-way and N-way Multivariate ANOVA. (Solutions, 2013) The determining factor when to use one of the “ways” is dependent upon how many “treatments” are used in the study. We use the term treatment because ANOVA originated in the 1920’s to test different...

...MathStudies: Units Project
Talha Mirza
1A Gilmartin
Dear noble tribe leaders of T-Island, I have created a brand-new system of units for us to use in our daily lives called the T-Dog system. You will find this system to be quite useful, as it includes six unique units which measure temperature, length, time, weight/mass, volume/displacement, and currency. By utilizing these units, life will be made easier for us. Moreover, if it is ever decided to switch to other well-known systems, it is possible as each unit has a simple conversion to the metric system. Lastly, there are 5 situations attached to this proposal which exemplify the simplicity and convenience of using the T-Dog system.
The first unit in the T-Dog system is “Sweats” ( ), a measurement of temperature.
This measurement was invented by the unique Talha Tribe, who were the first ones to employ the use of this ingenious system.
This measurement is used to calculate and measure heat, specifically the temperature of any given atmosphere, and depict the weather.
This measurement is based on the amount of sweat one produces under a given amount of heat; therefore this unit was given the name “Sweats”.
The symbol used to designate the “Sweats” unit is a small water/sweat droplet. This symbol was created to visually represent the unit of “Sweats”.
The “Sweats” unit, in relation to the metric system would convert by the following:
1 Sweat = 10 ° Celsius

What is the Relationship between Points per Game Scored and the Height of the Players in the NBA?
Introduction:
The NBA is one of the United States’ favorite sports leagues, with each team averaging 100 million dollars of income each year before expenses. Quite a bit of money is spent gambling, funding, and keep the public entertained with this sport. To keep this system working, and to get a fair share, all the coaches must attempt to keep their team on par with the others if not above their competitors. Knowing this, having any type of advantage could be quite profitable for a team. If there was a known way to give your team an advantage it would be utilized and be quite profitable. Height happens to be a physical characteristic that may play in role in having an advantage. If being taller does in fact give a player an advantage, then why not just hire the tallest players you can in order to get the biggest advantage?...

Math Processes
I used a scatter plot graph for students who were in a relationship so I can plot their GPA score and their involvement score from the Relationship Involvement Scale. I also used a line graph to plot students who were single to show their GPA scores. Since the students were single, there was no need to assess their relationship involvement; therefore they were not given the Relationship Involvement Scale.
For my first mathematical process, the product moment correlation coefficient test to find out if my data is positively correlated, negatively correlated, or if they are not correlated. I input my relationship involvement score into L1, or x, of my calculator. I then input my GPA scores into L2, or y. I got a scatter plot similar to the one I got in Microsoft Excel. The value I got for R (Coefficient of Determination) is 0.05516441. Since this number is between 0 and 0.1, it shows a very weak positive correlation.
For my second mathematical process, I will be doing the test of independence. The chi-square test of independence is used to determine whether two variables from the same sample are independent. In this experiment, the two variables are GPA Scores and Relationship Status. By using the chi-square, I will determine whether the relationship status and the student's GPA score...

ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which resists relative lateral motion of two solid surfaces in contact and is subdivided into static friction between non-moving surfaces, and kinetic friction between moving surfaces; lubricated friction which is a case of fluid friction where a fluid separates two solid surfaces; skin friction which is a component of drag, the force resisting the motion of a fluid across the surface of a body; internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation and sliding friction.
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to heat whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence of many types of friction can be wear,...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also be communicated to the offeree before it is being accepted. In addition, the acceptance has to be unqualified, unconditional and made by a positive act. In the case of Beauty and Stylish, a positive act refers to the signing of the contract. All terms of the offer must be accepted without any changes and cannot be subjected to any condition, taking effect only upon fulfillment of that condition. When Beauty and Stylish enter into the agreement, they must intend to bind and bound legally to each other by their agreement. This is the intention to create legal relations between two parties. In the meanwhile, this contract must possess consideration. A contract must therefore be a two-sided affair, with each side providing or promising to provide something of value in exchange for what the other is to provide.
Every contract, whether oral or written, contain terms. The terms of a contract set out the rights and duties of the parties. Terms are the promises and undertakings given by each...
