<h1>How to tackle Statistics problems</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p>This article mainly reveals the basic concepts of statistics and statistics help in different areas of studies and researches. Firstly we need to know about statistics. It is the practice or science of collecting and analyzing numerical data in large quantities. It is basically a study of the collection, organization, analysis and interpretation of the data.</p> <p>Statistics is the core of research. Completing the data collection and analyzing it forms the base of research paper. Statistics is the science which deals with variations, randomness and chance. It is different from other science as others work or study on exact deterministic mathematics laws. In a lot of statistical analysis and experiments, the result depends on probability distributions as probability plays an important part in statistical analysis, Statistical analysis uses probabilities and probability calculations uses statistical analysis. For example in an experiment in social science, we assume a normal or common distributions for sample and population. The normal distribution is one of the probability distribution.</p> <p>Probability and statistics together play an important role in finding out measures of central value, measures of spread, and helps in comparison of data . Probability and statistics are closely related with each other.</p> <p>Example for calculating central value for 4 and 6, it is calculated as (4+ 6)/2 = 10/2 = 5. example for calculating a range for 9, 11, 4, 8, 5, 6, 2000, the lowest value is : 4 and the highest value is : 2000 then the range is : 2000 – 4 = 1996.</p> <p>Online Math Tutors provide prompt, reliable, and understandable information about data analysis to students. Online tutors for free help people in making effective decisions in uncertain situations. Probability is used to illustrate events that do not take place with certainty. Statistics reveals the concepts of association between two variables, probability, random sampling, and estimation.</p> <p>statistics help is available in different areas like weather forecasters use statistics to more precisely predict the weather. engineers use statistics to scale standards for product safety, security and quality. scientists employ statistical methods to conduct efficient experiments. economists apply statistical techniques in foreseeing future economic tendencies.</p> <p>Online Math tutors can help you overcome all the challenges of statistics problems and providing you with the highest quality statistics homework solutions and probability homework solutions. It provides on-demand tutoring service which no other online tutoring companies offer. Statistical help requires collecting and cleaning the data at the first stage. After understanding the basic story behind it, variables and data size are analyzed, it is important to select the most appropriate statistical test. Online math tutors are available for students of all grades, whether tutoring is needed for class 12 grade students struggling in Math class or college students with Algebra, Online math tutors provides full solutions to their problems.</p> <p>Statistical analysis can be done by using mean of a number list or data: The mean of a list of numbers is also called the average. It is found by adding all the numbers in the list and dividing by the number of numbers in the list. Let's take an example : Find the mean of 11, 11, 4, 10, 11, 7, and 8 to the nearest hundredth. (11 + 11 + 4 + 10 + 11 + 7 + 8)/7 = 8.857… which to the nearest hundredth rounds to 8.86.</p> </p><strong>About the Author:</strong><br /><p>TutorVista is the #1 portal for learning <a rel="nofollow" href="http://math.tutorvista.com/" title="online math tutors">online math tutors</a>.
