Specific statistical methods have helped the civilization to identify, study, and solve a variety of problems. Statistics help people make 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. People in various occupations tend to apply statistics.
Health specialists use statistical methods to resolve whether a particular drug or procedure is useful in the treatment of medical issues. 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. Questions in statistics and probability can sometimes be pretty tricky and acquire a lot of time, knowledge and effort. It also sometimes occurs that the assignments do not always correspond with the knowledge and information given to the students within the course. By convention, statisticians have agreed on the following rules. Thus, if event A were very unlikely to occur, then P A would be close to 0.
And if event A were very likely to occur, then P A would be close to 1. Example 1 Suppose we draw a card from a deck of playing cards. What is the probability that we draw a spade? Since there are 13 spades in the deck, the probability of drawing a spade is. Example 2 Suppose a coin is flipped 3 times. What is the probability of getting two tails and one head?
The event "getting two tails and one head" consists of the following subset of the sample space. The biggest reason is that there are so many statistics concepts for you to learn and master. During the study of statistics, you will learn everything about how to collect, analyze, present, and interpret data. Your homework assignment may become even tricky when it requires you to collect, summarize and represent data as graphs.
It is not easy for every student to handle such an assignment, and that's the reason why college students look for statistics homework help online. Normal Distribution Computing Binomial Probability.
