Statistics contains the development of procedures and tests that are used to describe the variability characteristic in data, the odds of certain outcomes, and the fault and doubt related with those outcomes. Some statistics are influenced, some are based on beliefs, and some are false. A frequent misunderstanding is that statistics gives a degree of proof that something is accurate. As an alternative, statistics provide a measure of the probability of observing a certain outcome. It is easy to
BIOSTATISTICS 1.Explain what is meant by descriptive statistics. (5m) Descriptive statistic is refer to data analysis that aid in describing, showing or making summary of data features in order to get meaningful data from the raw data itself, but do not to allow us to make a conclusion beyond data that we have analysed, it is just to simply interpret the data in a simpler way. These can be done by using chart, table, graph, narrative or pictures. There are two ways in which we can describe data:
Statistics are necessary for scientific research because they allow the researchers to analyze empirical data needed to interpret the findings and draw conclusions based on the results of the research. According to Portney and Watkins (2009), all studies require a description of subjects and responses that are obtained through measuring central tendency, so all studies use descriptive statistics to present an appropriate use of statistical tests and the validity of data interpretation. Although descriptive
Discussion: To analyze the data set, the analytic method I used was the regression analysis. Here I will discuss the results and what they mean. Descriptive statistics: Valid N is the number of valid observations for the variable. The total number of observations is the sum of N and the number of missing values. In this data the number of valid observations is 20. The minimum (8) is the smallest number in the data set whereas, maximum (26) is the largest number in the data set.(Hon, pp 3-5) Standard
As a population, we are bombarded with percentages and statistics, but how does one know if what we are being told is correct? The book How to Lie With Statistics by Darrel Huff was written to help readers better understand statistics especially when they are presented to us in ways that can be misleading or misunderstood. The book is not meant as a guide on how to change or manipulate statistical numbers. However, if statistics are not presented properly or perhaps purposely misleading people,
Write a short summary that addresses the following criteria: • Define “statistics”. • Identify and describe different types of statistic and levels of measurement. • Describe the role of statistics in business decision making. • Provide at least three examples or problem situations in which statistics was used or could be used. • Format your paper according to APA standards • The University generally requires formal papers to use section headings to establish structure. For this short paper, section
it to report their work, it is important for them to understand some of the basic tenants behind research and data and arguments we usually hear about defender data collection. Defenders have posed a variety of arguments against using the case statistics in an evaluation of office and attorney performance. First, defenders rightly argue that no two cases are alike, suggesting that techniques that combine cases for statistical purposes neglect essential differences. Second, defenders have pointed
Statistics We define statistics as a branch of mathematics as a means to analyze, understand what we observe and explain synopses, so as to create sense and meaning of our explanations and observations. Each day in life we come across information that originates in various forms. This is to means in order to put sense in this information; there is the necessity to use statistics. Though, due to its empirical applications and focus, statistics is typically regarded as a distinctive math’s sciences
In this article, the authors attempt to answer the research question of whether or not the link between an individual’s organizational citizenship behavior (OCB) and the score they receive on their performance evaluation is affected in any way by gender. OCB is described by the authors as actions that are performed by individuals that go above and beyond what is expected of them as per the requirements that are listed on their job description. For the purpose of this study, the authors looked at
Descriptive statistics What is descriptive statistics? Usually under descriptive statistics summative methods of description the data in succinct ways is considered. Data analysis usually begin with descriptive statistics, because it helps to understand what data we have – what is the sample, what is the accuracy of the data and how it is possible manage it. The analysis of data usually begins with such descriptive statistics as the mean, median, mode, variance and standard deviation. Mean, median
