Questions On Non Probability Sampling
1039 Words  5 Pagesjournal entry will define what nonprobability sampling is and the different types such as snowball sampling, quota sampling, convenience sampling and purposive sampling. In addition, the pros and cons of nonprobability will be discussed such as the correct sample size, determining the desired precision, and managing the variation in the population to name a few examples. Furthermore, this journal will discuss why a researcher might want to use nonprobability sampling over other methods such as…

Analysis Of Variance And Probability Of Error
875 Words  4 PagesAnalysis of Variance is utilized when we want to “Compare multiple groups without increasing the probability of error. The Analysis of Variance (ANOVA) is such a test” (Mirabella, 2011, p. 56). When computing this test it is always nondirectional. As we are only testing to see if there is a difference or if there is not a difference (Mirabella, 2011). Furthermore, ANOVA allows you to compare an infinite amount of groups. In our case, we are conducting a hypothesis test using Analysis of Variance…

Mathematics: Probability
3333 Words  14 PagesIntroduction The word Probability derives from probity, a measure of the authority of a witness in a legal case in Europe, and often correlated with the witness 's nobility. In a sense, this differs much from the modern meaning of probability, which, in contrast, is used as a measure of the weight of empirical evidence, and is arrived at from inductive reasoning and statistical inference. A short history of Probability Theory............ The branch of mathematics known as probability theory was inspired…

The 'But for' Test and 'Balance of Probabilities' Essay
1712 Words  7 PagesThe ‘but for’ test and ‘balance of probabilities’ are used to determine whether the negligent act was the cause of injury. The ‘but for’ test is ideal for cases like Barnett where ‘but for’ the negligence of the doctor the claimant would have died because of the irreversible implications of ingesting arsenic. More complex cases require the ‘balance of probabilities’ to illustrate the chance of recovery and the diminished prospects as demonstrated in Wilsher where the injury could have been sustained…

260 Words  1 Pages1. A card is drawn at random from a standard 52card deck. Find the probability that the card is not a queen. 52 card 4 queens = 48 cards that are not queens. 48/52 = 12/13 or 0.923 = 92.3% probability of not drawing a queen from a standard 52card deck. 2. Two fair dice are rolled. Find the probability that the sum of the two numbers is not greater than 5. 1+1, 1+2, 1+3, 1+4, 2+1, 2+2, 2+3, 3+1, 3+2, 4+1 are the 10 possible occurrences of two fair dice rolling numbers not greater than 5. With…

Conditional Probability Of Probability For Statisticians
1471 Words  6 PagesConditional Probability Huafeng Zhang I. Introduction Everyone in a way use conditional probability even if they don’t realize the science behind it. Nonstatisticians use conditional probability without recognizing it mostly when they make decisions or judgments, for example they will be less likely to lend money to people who borrowed his money but haven 't returned the money back. Statisticians think of conditional probability in both logical and quantitative way. II. Conditional Probability for Statisticians…

Probability Concepts
893 Words  4 PagesProbability Concepts Introduction Probability concepts describe how uncertainty can be quantified, and it measures the possibility or impossibility of occurrence of a given event. Probability is the chance of a particular outcome, out of a number of times possible outcomes occurring for a certain event. These concepts help in making inferences about situations and to quantify the uncertainty of future events. It is, therefore, useful to review basic concepts and laws of probability to understand…

Black Males And Male Males
1552 Words  7 Pagesonly 8% of white males and 6% of Chinese males. On average, black males experienced 3.4 police stops in the past two years, compared to 0.7 stops for white males and 0.5 stops for Chinese males. Although black females are less likely to be stopped and questioned by the police than black males, they are significantly more likely to report police stops than white or Chinese females. In fact, black females (9%) are more likely to report three or more police stops than white…
