Most Important Things to Carry to a College

Often most college-going students face the issues of forgetting things that are very important. It is not that they forget it from the very beginning but, the chances of forgetting things is high during last minute preparations. There are certain things that are absolutely essential, especially when the student is going to share a room.

These personal things will come in handy in most of the day to day activities. Having couple of these things will make things easier. Often the things that we take for granted will help us in simple but time consuming situations.

• First-aid kit: A First-aid kit is one of the most important things that one needs to carry. We’re not saying that people are going to get hurt, but if something goes wrong, then a first aid kit will come in handy. Make sure that all the medicines, ointments, anti-septic liquids or creams and bandages are not empty.
• Power cables, Plugs and Adapters: Don’t forget to pack your power cables, plugs and adapters. Will help you charge mobile, ipod and other useful things. If you are a gadget-freak, then you would definitely want to carry them.
• Flash or Thumb drive: A flash or a thumb drive can be your life saver. Carry it always just like your wallet. It help you transfer important stuff from your friends computer to yours when you are in dire need of it.
• Laptop lock: As the dorm rooms are shared, there is a chance that your laptop might be stolen. Don’t let that happen. Instead put a lock on it so that nobody can steal it.
• Bathroom shoes: Carry a pair of bathroom shoes or shower shoes along. You don’t want to use dirty and unclean shoes of someone else.
• Sewing kit: The humble needle and thread can be your life saver in times when your torn clothes can be the cause for your embarrassment. Don’t let that happen to you.
• A small tool kit: A small tool kit will come in handy in fixing things in your dorm room as well as adding or removing hardware to your computer. Don’t carry heavy professional tool kits. Carry simple but optimum tools in terms of space and efficiency.
• Containers and Boxes: Containers/ boxes can help you store your things like your assignment papers, books, your personal stuff, etc. Dorm rooms lack space and don’t have many cupboards, so do carry two or three of them.
• Incense Sticks or Room Fresheners: Carry 2-3 Incense Sticks packs or Room Fresheners with you as they are needed in dorm rooms because most of the times dorm rooms are dirty and stinky places, especially boys’ rooms compared to girls rooms.
• Rain coat and an umbrella: A rain coat and an umbrella can be useful during the rains. Carry them along with you during rainy days. You can miss the college altogether and you can’t afford to get sick and miss some important classes.
• Spare plates, spoons, forks or chop sticks: Spare plates and spoons will be of good use if you want to eat something in the room. Especially useful for those mid-night snacks and snacks between meals.
• Stationery Items: Stationery things like papers, pencils, pens, erasers, paperclips, sticky notes, staplers, glue, whiteners and file folders will help you through your paper work and academic work in college smoothly.
• Baskets and detergents: Baskets and detergents will come in handy while cleaning your clothes. Wash your clothes at least once every 10-12 days. These will come in handy while washing.
• Soap, shampoo and razors: Carry your personal hygienic stuff like soaps, shampoos and razors along with you. It’s the question of personal hygiene and health.

These are generally the things that a student requires while staying in a dorm room. This might look like a big list of things to carry. But, carrying them before hand will help you avoid unnecessary issues.

Statistics at HelpWithAssignment.com (Correlation)

In Statistics Correlation denotes the relation between to variables. If change in one variable is initiating change in the other variable then it is said that there is a correlation between them. There are two kinds of correlation. One is Positive Correlation and the other is Negative Correlation.
Positive Correlation is said to exist when a change in one variable is causing a positive change in the other variable as well then it is called Positive Correlation. For example, there is said to be a Positive Correlation between Income and spending. As income increases so is the purchasing power and spending.
Negative Correlation on the other hand is a positive change in one variable causes a negative change in the other variable. The best example for this is the demand theory in Economics. We all know that when price of a product increases then the demand of that product decreases and when the price of the product decreases then the demand increases.
The result of Correlation can only range between -1.00 and +1.00. If the answer is -1.00 then it is called perfect Negative Correlation and +1.00 denotes a perfect Positive Correlation. 0.00 denotes that there is no correlation at all.
Let us understand the process of Correlation with a good example.
The Mean of X and Y are calculated to be 4.7 and 79.9 respectively. The Standard Deviation of X and Y are calculated to be 2.1628 and 11.5706 respectively.
Now, the formula for Correlation Coefficient or Karl Pearsson Correlation (r) is

Here, we can observe that the ∑XY = 3939; N¯X ¯Y is the means of X and Y, calculated to be 4.7 and 79.9 respectively. Standard Deviation is denoted by Sx and Sy which are calculated to be 2.1628 and 11.5706. When we apply the values we get

r = (1/(10-1 ) (3939-10(4.7)(79.9) ))/((2.1628)(11.5706))
r = (1/(9 ) (3939-3755.3))/25.0249 = (1/(9 ) (183.7))/25.0249 = 20.4111/25.0249 =
0.8156 = 0.82

The Coefficient Determination = r2 = 0.822 = 0.67 or 67%.
Therefore, we can conclude that the score in exams is directly related to the number of hours studied to a significant extent. And we can say that there is a positive correlation between the Number of hours Studied and the Scores obtained in Exams.

Are you looking for Mathematics Online Tutoring services, your search ends here

Mathematics! This subject gives nightmares to many students and some students are really bored by the student. Often many teachers and parents complain that children do not score well in mathematics apart from being good in other subjects. Some children are really afraid of the subject that they do not want to talk about it, even casually.

Many teachers complain lack of attention in mathematics class. This is due to the fact that one teacher has to teach a class of 20-30 students. It is a very low chance that all the children have identical or similar abilities of grasping subjects, especially mathematics. This makes the class even more challenging for the teacher. So, they are not able to concentrate on all the children in the same way and give equal importance to all students. Only some students can grab the attention of the teacher and some cannot. This is more or less the same situation in a regular tutoring institution. One tutor teaches a group of say 10 students. Even here, the weak students try desperately to grab the tutor’s attention and they fail ending up with many doubts in subjects, especially mathematics. This can only mean one thing; those students find it hard to move forward in their education and careers.

A best alternative to this situation is the online tutoring. Online tutoring unlike conventional tutoring sessions, hold their classes online and we all know that.

Tips on Writing a Good Speech

Speech writing is one of the important activities that students have to go through. Speech delivering has been used in the curriculum so that students will be more confident in addressing a group of people. Stage fear is one of the fears that students can overcome only by facing it. Otherwise, this fear will remain for a long time.

Now let us discuss some points on how to write a speech.

A speech should contain an introduction, a body and a conclusion. Please ensure that the introduction is not more than 3-4 sentences. Limit the body to 7-8 sentences and the conclusion can be about 2-3 sentences.

Begin the speech with the introduction of who you are the topic that you will be speaking about and the purpose of the speech. The purpose of the speech is very important.

The body can be broken down into points for the sake of ease of delivery. If you are going for a points instead of a paragraph please ensure that the most important point is discussed first and the rest of the points follow.

A good writer must write with the final takers kept in mind. In this case, it is the listeners, about whom one must think. Think from the viewpoint of the listeners and write. Do not write something that can offend the listeners.

Check for the length of the sentences and the tone of your language. Lengthy sentences can make the listeners lose interest and the tone of the language can sometimes offend them. Choice of words is an important aspect that one should be careful at.

Try keeping the speech simple and brief and also informative at the same time. This is a tough job, but one must balance it because of the time being allotted to each student.

Support you views and ideas by providing statistical evidence, facts, examples, quotations and a pinch of humor to ease the environment.

The conclusion should contain the advantages in brief, your views as the writer, recommendations if necessary. This is about the conclusion part. The conclusion part should also include the main purpose. This will leave the listeners with a good impression.

A good speech is not just about a well-written script in hand and reading it out loud but a good interaction with the listeners. The listeners will like the subject when the speaker is in an interactive mode, asking questions and giving answers to the listeners, thereby making the speech more interesting.
