Statistics is the branch of applied mathematics, which deals with the collection, organization, and interpretation of numerical data, especially the analysis of population characteristics by inference from sampling. Statistics has been described as the science of making conclusions in the presence of uncertainty. Statistics has strong mathematical foundation and due to its practical nature it has wide areas of application in fields like bio-statistics, bioinformatics, climatology, computer science, psychology, finance, econometrics etc. Statisticians improve the quality of data with the design of experiments and survey sampling. Statistics also provides tools for prediction and forecasting using data and statistical models. Statistics is applicable to a wide variety of academic disciplines, including natural and social sciences, government, and business. All research work generally rely upon statistical calculations and analysis.It serves as a base for all research work all around the world.Today we have software’s on statistics on which we can work upon all the calculations very fast and easily.The major software’s are minitab, SAS, SPSS, STATA, MATLAB. There are many statistical tools and techniques, one being Descriptive statistics. Descriptive Statistics deals with the methods of organization, reduction, and presentation of data in order to make them amenable to rational analysis and interpretations.
The level of complexity of statistical problems varies. It may range from computation of simple measures like mean, median and mode to computation of standard regression results and complicated forecasts using time series data. Across all colleges students are often tested on these topics. Tutorhelpdesk provides specialized services in all these software’s.Experts are well trained and experienced in all topics starting from basic level Statistics to advanced college level Statistics. We provide homework assignment help in all areas of Statistics listed below. Probability theory is very important topic of statistics. students often get stuck in probability problems and statistics homework problems .
The probability of a given event is an expression of likelihood of occurrence of an event. A probability is a number which ranges from 0 (zero) to 1 (one) – zero for an event which cannot occur and 1 for an event which is certain to occur. The word ‘probability’ or ‘chance’ is very commonly used in day to day conversation and generally people have a rough idea about its meaning. Probability today has become one of the basic tools of statistics. In fact probability and statistics are so fundamentally inter-related that it is difficult to discuss statistics without an understanding the meaning of probability.
A knowledge of probability theory makes it possible to interpret statistical results, since many statistical procedures involve conclusions based on samples which are always affected by random variation, and it is by means of probability theory that we can express numerically the inevitable uncertainties in the resulting conclusions. Tutorhelpdesk.com offers online probability homework help and probability assignment help in all areas of probability theory.
