Studying this world and its phenomena using mathematics has been an age old process for science and technology.It began with counting objects and now is used in every aspect of society. Role of mathematics in our civilization is impossible to deny.
For that reason, math is now a subject in elementary studies and also in several higher education streams, definitely including science. Home assignments on math are very common from much junior stage to test young studentsâ€™ competency. This often calls for college homework help.
A very important part of math is statistics or stat, which is our main concern here. It is so useful and powerful that now it is an independent subject taught in colleges and universities. Naturally, calls like, â€˜do my statistics homework for meâ€™ are often heard in these institutions.
Students who all study stat are always on a more beneficial ground than others, because they can change to a wide variety of subjects from there. But, in order to be a good student, you should not always cry for help, â€˜do my statistics homework for meâ€™. Rather try to do it yourself.
For readers who do not know much about this subject or who are very new, let us run an introductory course. What is this stat all about? It is a mathematical dealing of a large number of similar objects to predict future and possibilities from them.
Before you ask someone, â€˜do my statistics homework for meâ€™, you should find out how much you actually know or can tackle.Do you know all the important parts of this subject and its terms? If not or if you have forgotten, this is the right place to brush them up.
Terms and definitions
In logical subjects like, science, math or stat, terms, their usage and definitions are very significant. If you want to stop asking, â€˜do my statistics homework for meâ€™, you must at least have these ready in your mind. Let us now see some of the useful and popular terms.
As we know, stat deals with a collection of objects and some physical quantities associated with them. Finding central tendency of one of those quantities is a popular task to do. Central tendencies are of four main types
- Mean or average â€“ Concerned quantity for all objects in the collection are summed up and then divided by total number of objects.
- Root mean square or R.M.S. â€“Square of the quantity summed up together, divided by number of objects and then square rooted. It is useful when this quantity being calculated, involves sign.
The latter two are rarely used and mostly obsolete in scientific calculations. But, they may be part of questions or tasks in innovative projects. If you have a fair knowledge on them, you cn tackle it yourself instead of shouting, â€˜do my project for meâ€™.
There are other terms too that are used here and without knowing which you will have no choice but to utter, â€˜Somebody do my statistics homework for meâ€™. These terms include:
- Variance â€“ it is the difference or R.M.S.and mean value of a quantity.
- Standard deviation â€“ it is the square root of variance. It basically gives
- Sample space â€“ It is the collection of objects and possibilities that are concerned in a certain case
- Venn diagram â€“ a pictorial representation of possibilities and cases that are useful in statistical formulations and analysis.
Probability is perhaps the most significant part of this subject. Why then is nothing written about it above? It is because we feel that if you happen to be thinking, â€˜Who will do my statistics homework for me?â€™, then definitely you require a separate paragraph dedicated to knowledge of probability.
Probability â€“ the heart of stat
As anyone can guess from its name,it is a measure of possibility or chance of some event. If there are three colored balls, red green and blue in a box, then what will be the chance or possibility of getting a black ball? The answer is simply zero, as it is not possible.
Now, if you do not want to beg to others, â€˜Please do my statistics homework for meâ€™, then you should know at least how to calculate simple probability. For example, how will you calculate probability of getting 2 in a dice throw?
What are the possible outcomes of a dice throw and how many? It is 6, right? And getting a 2 is just one of them.
This means chance of getting 2 is 1/6, 0.166 or 16.6%. So the simple formula for probability is number of favorable events divided by total number of possibilities. Apart from that we also have other definitions and derivations of probability.
Probability distribution is another important part here, when the collection or possibilities are too large to count. The continuous probabilistic functions are introduced and they give probabilities in a range.

Usefulness of stat
Stat is a subject which is widely used in all sorts of science. There is hardly any science which does not deal with collection of objects, data and quantity.So there is no shortage of requirement of stat.
It is often termed that statistics serves all other subjects when it is called. In brief, stat takes up things from where other subjects fail. For example, statistical analysis helps to predict economic, political and other collective situations in a region or nation.
They are used to average out weathers for long period of time and assists in whether forecasting and others. Other science subjects too require statistics. E.g.
- Physics â€“in statistical and quantum mechanics
- Chemistry â€“ to understand collective behavior and quantities related to reactions
- Biology and medical â€“to analyze outcome of medicines and collective health issues.
If you are planning to make a career out of stat, then fear not. You will have plenty of job and career opportunities. But you must make sure that you ask, â€˜do my statistics homework for meâ€™ to the right persons.
